Mikel Arteta is unsure if Kieran Tierney will play for Arsenal again this season after the left-back was ruled out for four to six weeks with ligament damage to his left knee.

The full-back limped off during the Gunners' disappointing 3-0 reverse at home to Liverpool on Saturday and required further checks on the severity of the issue.

An Arsenal statement said Tierney will not require surgery on the injury but with the Premier League campaign coming to an end on May 23, he may not feature again for Arsenal this term.

It is also unfortunate timing for Scotland, who play their first match of the rescheduled Euro 2020 finals against the Czech Republic on June 14, with the first of two warm-up fixtures taking place against the Netherlands on June 2.

"It could have been worse, he's feeling better, the damage is not that bad," Arteta said when previewing the first leg of Arsenal's Europa League quarter-final tie against Slavia Prague.

"We have to go day by day to see how Kieran is feeling. Depending where we are and how he's feeling, we'll make this decision.

"It will depend on how things evolve. He is keen to play for us again this season and obviously his country in the Euros."

Tierney's injury is particularly problematic as Arsenal do not have another out and out left-back in their squad, with Sead Kolasinac having left for Schalke in January and Arteta unable to find a suitable replacement.

"We're going to have to make some adjustments. His qualities are unique. We don't have anyone to replace these qualities," Arteta added. 

"We're going to have to find different ways to fulfil that gap and use all the things that can be as effective as well.

"We could not do anything in that window. We let Kolasinac out on loan and it's a decision that we made."

Bukayo Saka could be one solution to fill the void a little deeper down the left, with Arteta saying: "That's the reality: you have to change something, find a different way of attacking, find a different structure.

"It has to be stable and done by players who are doing that. We knew that position was a weakness around the squad. We have to find different solutions."

Saka himself has been contending with a hamstring issue but he, Emile Smith Rowe (thigh/quad) and Granit Xhaka (illness) are all in training in the hope of featuring, while Martin Odegaard will be assessed having struggled with an ankle problem since returning from international duty with Norway. David Luiz is still recovering from a knee injury.

The match against Slavia is particularly important for Arsenal, who put in an abject showing against Liverpool and know their most realistic chance of returning to European football next term is winning the Europa League having slipped to 10th in the Premier League.

Arteta feels the "big punch" inflicted by Liverpool may ultimately be a good thing for his side.

"I cannot criticise [the] hard work or ethic of my players, it's not about they don't want to run or try. There are areas where we are inconsistent, my demands are to be hitting those goals, achieving our best level every day, whether it's training or game day," he said.

"I didn't see anything different, that's why it was a big shock what happened against Liverpool, it's part of the journey, sometimes a big punch or slap in the face is good to return to reality.

"This competition is all or nothing because when you play a tie you are in or out. We know how important the game is for us."

With the Premier League back following the international break, all eyes were set to be on the Emirates Stadium for a heavyweight clash between Arsenal and Liverpool.

Or, that's what the nostalgia of the Premier League wanted us to expect – the reality was rather different, as Arsenal's current status as Europa League-hopefuls at best was made brutally clear.

In fact, as it turned out, the day's most-compelling viewing came from elsewhere in London, as Chelsea suffered an abysmal home defeat by West Brom.

In the East Midlands, Manchester City took their customary step closer to the title, while Leeds United came out on top in an all-Yorkshire affair.

We have taken a look at all the best Opta facts from the four games.

Chelsea 2-5 West Brom: Blues bruised by Big Sam's Baggies in momentous defeat

It was a day to forget for Thomas Tuchel and Chelsea as their honeymoon period came to a bruising and humiliating end in a 5-2 home defeat by relegation-threated West Brom.

Chelsea did take the lead through Christian Pulisic, his first goal in 21 games across all competitions, but Thiago Silva's red card for two bookings in the 29th minute offered encouragement to West Brom.

Matheus Pereira's first-half stoppage-time brace – the goals separated by just two minutes and 46 seconds – put the Baggies in front, and Callum Robinson got a double of his own in the second period, becoming the first player in Premier League history to score at least twice home and away against Chelsea in a single campaign.

Mason Mount and Mbaye Diagne got the other goals, with Chelsea conceding five times in a home Premier League game for only the second time, the last being against Arsenal in October 2011.

Victory ensured Sam Allardyce became the first manager in Premier League history to win at Stamford Bridge with three clubs, while it was Tuchel's first defeat since replacing Frank Lampard in January.

The hard work starts here.

Leeds United 2-1 Sheffield United: Blades approaching new low

Sheffield United have looked doomed virtually all season – no win over Leeds United at this stage of the season was going to change that.

But in losing at Elland Road, it took them to 24 defeats in the league this term from 30 games – only twice in their entire history have they suffered more losses in a single campaign, 26 in 1975-76 and 2010-11, though on both occasions were from many more matches (42 and 46, respectively).

For Leeds, however, the win saw them complete a league double over their Yorkshire rivals for the first time since 1991-92 when they actually won the top-flight title.

While no one is expecting them to go close to repeating that title feat anytime soon, Saturday's visit of Blades did provide another reminder of the positivity Leeds have brought to the Premier League – it was the fifth time this term they have attempted at least 20 shots (23 this time) in a single game, with only Manchester City doing so more often (six).

Jack Harrison's opener was one of them, with the winger netting his seventh goal of the season to make this his best ever campaign in English football, while Raphinha teed him up to move on to a Leeds-high six assists in the Premier League in 2020-21.

They needed a helping hand, though. The seventh own goal of Phil Jagielka's career – only Richard Dunne (10) has more – proved decisive, making him the oldest outfield player (38 years, 229 days) to score in his own net in the top tier since Stuart Pearce in 2001 (38y, 252d).

Leicester City 0-2 Manchester City: Guardiola has the key to cleansheets

When you think about what Pep Guardiola the coach is associated with, 'tiki-taka', free-scoring teams and ball-playing centre-backs spring to mind immediately.

But now, perhaps we should add defensive solidity to that list?

Granted, Guardiola has coached great teams for the majority of his career, and they wouldn't usually have poor defensive records, but his runaway City side seems arguably one of his shrewdest ever.

After Saturday's 2-0 win at Leicester, who although third in the table were utterly subjugated, City have kept more clean sheets (28) and conceded fewer goals (26) in all competitions than any other side in Europe's top five leagues.

They prevented Leicester from mustering a single first-half shot for the first time in the league since December 2019 (against Liverpool), and the Foxes suffered just their third defeat in their last 17 top-flight outings.

Among the scorers for City was Gabriel Jesus, who continued his remarkable unbeaten run in games he's scored (41 – W39, D2), a record only James Milner (54) and Darius Vassell (46) can better.

It was the fifth league goal Jesus has managed against Leicester, making them his second-favourite opponent after Everton (seven goals against).

However, Sergio Aguero was unable to cross another stadium off his list. He's played four times at the King Power Stadium without scoring – only two other grounds has he a worse goalless record (eight games at Anfield, six at Selhurst Park). Following the announcement of his end-of-season departure, it seems Leicester have largely avoided his wrath.

Arsenal 0-3 Liverpool: Arteta questions mount with his record not standing up to Emery's

Mikel Arteta's 50th Premier League match as Arsenal coach was one to forget – though it feels like we could say the same thing about rather a lot of his previous 49 games.

Brought in as Arsenal attempted a hard restart, ushering in a new 'era' with fresh ideas, Arteta it was hoped would turn the Gunners back into title challengers, but it seems as though they're even further away from that than under much-maligned predecessor Unai Emery.

This was Arteta's 17th Premier League defeat, four more than Emery suffered in his first 50 games, and the game itself suggested there remains a significant gulf between Arsenal and a Liverpool side that is nowhere near what it was last season.

Nevertheless, it is true that Liverpool's issues have mostly been consigned to Anfield recently, with each of their last six league wins – including this one – coming away from home. This is only the second time they've ever achieved such a run, the first recording since 1955.

Perhaps results against Liverpool aren't the best barometer to measure Arsenal against given they've beaten the Reds once in their past 12 Premier League meetings.

But Arsenal appear to be treading water under Arteta, with their points-per-game dropping to 1.3 from 1.7 in his second 25 league matches in charge.

Mikel Arteta said Arsenal's dire display against Liverpool had left him "in shock" after the Gunners surrendered 3-0 at home.

The seething manager attempted to take the blame for the performance, but disdain for the effort of his players was all too clear in the Spaniard's verdict.

Substitute Diogo Jota scored twice and Mohamed Salah also netted as Liverpool ran riot in the final half hour at Emirates Stadium.

Until then, Arsenal had been holding on, while never looking capable of going on to win the game. The home side had three attempts at goal, while Liverpool had 16 efforts on the way to winning by their biggest ever margin in an away league game at Arsenal.

Arteta told Sky Sports: "We completely deserved to lose the game. They were better in every department.

"They deserved to win the game with the margin that they have, or more. It was unacceptable from our side, the way we played.

"They won every duel, every second ball, every challenge. They were brave when they had the ball, they made the right decisions; we didn't.

"It was my fault. I had to set the team to play in a different way and perform in a different way. Congratulations to Liverpool because I think they were exceptional.

"We saw the difference today between the two teams, that when we perform at that level the margin is incredibly high.

"The standard has to be much higher from this football club and my job is to get them to perform at that level. We could not put three passes together. There were too many things that were not done right.

"At the moment I'm in shock. I didn't expect that, with the way the team trained, the way the team tries, but it happened. That is the reality."

Arsenal tackle Slavia Prague in the quarter-finals of the Europa League on Thursday. Arteta knows there must be a major response from his players.

He said: "If you have courage and you have big balls and you represent a club like this, you have to stand up in the next game and take it."

Mikel Arteta wants to help Pierre-Emerick Aubameyang rediscover his best form as Arsenal plan to treat every game as a final for the remainder of the season.

With the international break over, the Gunners resume their campaign on Saturday when Liverpool visit Emirates Stadium.

Both teams are desperately in need of points with just nine games remaining in the Premier League, or else run the risk of missing out on qualifying for Europe via the domestic route.

While Liverpool still have their sights set on a top-four finish, Arsenal go into the fixture well off the pace having won just three of their previous nine in the competition.

Like the team itself, Aubameyang has struggled for consistency in the competition. The Gabon international scored 22 league goals in each of the previous two seasons but has yet to reach double figures in 2020-21.

"We talked for months about the ratio of goals we need him to score to give us the best possible chance of being at the top," Arteta told the media ahead of the Liverpool game.

"He's not been what he has been in recent years, a factor that is contributed by a lot of other things that the team has to do on the pitch – it's not just his thing.

"Obviously, we need Auba in different form in the next games to give us the best chance to finish where we want to finish this season, that is clear."

Aubameyang could point to playing regularly in a wider attacking role as a reason behind the decrease in his productivity, with a nine-goal haul still one behind the total he managed in his first 13 league appearances after signing from Borussia Dortmund in January 2018.

His position in the team may also explain why his average of 2.28 shots per 90 minutes is comfortably lower than in previous seasons at the club, along with a shot conversion rate of 18.37 per cent (which is still better than Harry Kane's number of 16.67 per cent).

Yet when it comes to converting big chances – those Opta define as a situation where a player is expected to score – the 31-year-old sits at a healthy 45.4 per cent, well above his 2018-19 total of 36.1 per cent when he finished tied with Sadio Mane and Mohamed Salah for the Golden Boot. He is slightly outperforming his expected goals tally of 6.8 this term too, managing seven non-penalty goals from 47 shots.

Arteta recognises it is not necessarily all down to the player himself, with the Gunners manager asking for different requirements from his captain while instilling a more controlled approach to proceedings, laying the foundations for what he hopes will be long-term success under his guidance.

"He can play off the left, off the right, in the middle. He has done it, it's nothing new," Arteta replied when asked about Aubameyang's best position.

"When you look at his stats from the past, there is no difference. But it does depend [on] how we play, how much we provide for him and how efficient he is when he has these chances.

"When he has got this form of confidence, well, he is unstoppable. It is dependent on many factors."

The north London club rewarded Aubameyang for his previous exploits – including two goals to beat Chelsea in the FA Cup final last August – with a bumper new contract.

With the goals drying up since signing to stay for a further three years, questions have been raised over his commitment to the cause. He was also dropped from the starting XI prior to the derby with Tottenham in March for disciplinary reasons, though Arteta quickly drew a line under the issue in the aftermath of a much-needed 2-1 victory.

Arteta has no doubt Aubameyang remains ambitious, stating: "It's easy to connect things when they relate to it like that, but I'm not suspicious about that.

"We have had many conversations about what he wanted to do from last year's point of view with his future in the next three years. He was very ambitious with that, but to maintain that level is really complicated. He is trying hard and that's what he is aiming to do."

Arsenal could do with their captain leading from the front during the run-in, starting against Liverpool in what is the highest-scoring fixture in Premier League history.

"It's like a final every game," Arteta said ahead of the final stretch. "Three points mean a lot in the table and we need to go for them, we need to win as many games as possible. We know that."

Arsenal rising stars Bukayo Saka and Emile Smith Rowe face late fitness tests and David Luiz has been ruled out of the clash with Liverpool on Saturday evening.

Brazilian centre-back David Luiz must miss the Premier League game at Emirates Stadium, with Arsenal stating the 33-year-old has encountered "discomfort" in his right knee.

How serious that discomfort proves to be remains to be seen, with Arsenal saying the problem would continue to be examined.

Arsenal have a 36.8 per cent win rate in the 19 Premier League games that have featured David Luiz this season, compared with 50 per cent in the 10 games for which he has been absent.

They have collected an average of 1.4 points when he has played and 1.6 when he has not, with Arsenal heading into the weekend in ninth place, four points adrift of Liverpool who sit seventh.

In an injury update issued on the club website, Arsenal indicated winger Saka's right hamstring problem remained under observation.

The injury forced Saka out of England's three World Cup qualifiers in the past fortnight and although Arsenal posted a picture on Twitter of the 19-year-old in training, they said he "will be assessed ahead of Saturday's match regarding his availability".

The same applies for Smith Rowe, who suffered tightness in his right quad on England Under-21 duty, with Arsenal prepared to leave final decisions until closer to the game.

Manager Mikel Arteta faces a further wait to learn whether former captain Granit Xhaka is ready for the game, with the Swiss midfielder having missed training on Friday due to feeling unwell on his return from international duty.

Willian is available to Arteta, however, with the former Chelsea midfielder fully recovered from a left calf injury.

The 32-year-old has had the most assists (7) of all Arsenal players this season, across all competitions, with Smith Rowe and Saka (both 6) just behind the Brazilian.

Arsenal have lost just two of their last 20 Premier League home games against Liverpool (D9 W9).

Sergio Aguero has been one of the "three main faces" at Manchester City, according to Arsenal boss Mikel Arteta, who did not rule out a move for the striker.

Aguero's City career will come to an end at the culmination of the 2020-21 campaign, halting a 10-year stay at the club.

In that time, Aguero has helped City to four Premier League titles – scoring the goal which secured their first in the most dramatic of circumstances in 2011-12 – along with one FA Cup, five EFL Cups and two Community Shield triumphs.

The 32-year-old has struggled with injuries and COVID-19 this term, however, making just 14 appearances across all competitions, scoring three goals.

Arteta, Pep Guardiola's former assistant, worked with Aguero for over three years between 2016 and 2019, and has hailed the Argentinian's impact at City.

"Anybody that's been close to him would say the same thing, he's been the main face or one of three main faces to lift that project [at City]," Arteta told a news conference ahead of Arsenal's clash with Liverpool on Saturday.

"You need quality to create moments to build a project and his is the biggest face.

"Not only the way he plays, but his charisma and character. It's sad for him to leave but I think what he's done he will be their history."

Though denying he had called Aguero to discuss a potential switch to the Gunners, Arteta did not dismiss the suggestions of a move to bring the forward to north London.

"No, we will see what happens to him in the future," Arteta said.

"Sergio has a unique quality to see spaces that nobody sees and score goals in an easy way so I'm sure he will find the right next chapter."

One striker who has been linked with a move away from Emirates Stadium is Alexandre Lacazette, with the Frenchman's contract up in 2022.

LaLiga leaders Atletico Madrid are among the teams previously mooted to hold an interest in the 29-year-old, who has netted 13 goals in all competitions this season, scoring on each of his last three Premier League starts.

It seems likely Lacazette will lead the line again on Saturday, given he has scored in each of Arsenal's two most recent league games against Liverpool – the last Gunners player to score in three consecutive top-fllight games against the Reds was Robert Pires between 2003 and 2004 – and Arteta says the club will hold talks over a new deal at the end of the season.

|I'm always happy when people talk about our players and speculate – that means they're doing well and getting attention from other clubs," Arteta said.

"The situation with Laca we will address in the summer and speak to him and just propose the future that we want, and that's it.

"Up to now I just want players focused and only focused on performing and getting the best out of them for the team."

 

AGUERO OR LACAZETTE?

Should Arsenal decide to make a move for Aguero, then it may well be Lacazette who makes way, but would that be a wise move?

Lacazette is almost three years younger than Aguero, who has been besieged by injuries in recent seasons.

Since joining Arsenal at the start of 2017-18, Lacazette has made 122 Premier League appearances – 32 more than Aguero in the same timeframe.

The former Lyon forward has played a total of 8,219 minutes, compared to a figure of 6,214 for Aguero, who has started 75 games, 19 fewer than Lacazette (94).

However, Aguero has still scored more league goals, tallying 59 in contrast to Lacazette's 48, though it must be noted City's team of 2017 through to 2019 is widely considered as one of the finest attacking units of the Premier League era.

Lacazette has proved to be more creative, crafting 111 chances – 15 more than Aguero – though the duo are practically neck-and-neck for assists, registering 18 and 17 respectively.

Aguero's big chance conversion rate is better than Lacazette. The Argentina international has scored 42 goals from 78 opportunities from which Opta would have expected him to find the net (53.85 per cent); Lacazette, in comparison, has scored 30 from 70 (42.86 per cent).

Mikel Arteta believes Liverpool remain one of the top two teams in England as he prepares Arsenal for a crunch clash on Saturday.

The drastic dip in results from Jurgen Klopp's team since the turn of the year has seen last season's champions fall out of the top four in the Premier League.

They and Arsenal still have time to jump up the table, with Liverpool sitting seventh and Arsenal ninth heading into the weekend.

Liverpool's five most recent Premier League wins have all come away from Anfield, and another at Emirates Stadium this weekend would be a huge lift for Klopp and his players.

Arteta senses Liverpool are performing better in many respects than their results indicate, and suggested they are only outranked by one team - who would inevitably be Manchester City - in a range of key data performance metrics.

"I'm not the one to analyse what's gone wrong for them. I can talk about what they've done and what they are still producing," Arteta said in a news conference.

"I've seen a lot of games and the stats will support that. They are, if not the best, the second team in almost every department that we as coaches have to analyse.

"But then this is football and the ball has to be in the net - the final action has to provide a moment to win a football match.

"Then you have some individuals that dictate as well the quality of your team. Sometimes you cannot predict those things, so I think it's a lot of things."

Discounting penalties and own goals, Liverpool have netted 39 times in the league this season, yet their expected goals (xG) total is 44.3.

City's xG is slightly higher at 49.2, but Arteta's former club have far outperformed that mark with 58 non-penalty goals.

The trip to face Arsenal in north London has rarely been a successful mission for Liverpool in recent times. The Merseyside giants have won just two of their past 20 Premier League away games against Arsenal (D9 L9), a 2-0 success in August 2011 and a 4-3 victory in August 2016.

Arteta would relish another win to add to Arsenal's haul, knowing it would nudge them to just a point behind Liverpool, but he said his team would be "punished for every error".

Although the first leg of a Europa League quarter-final against Slavia Prague is coming up next week, manager Arteta says all the focus from his players should be on this weekend.

"For me, the priority is Liverpool," Arteta said. "We know if we want to climb up the table and have the chance to be in Europe next season through the Premier League, we need some consistency now in the last nine games.

"We need to get a run of winning matches, and the only way to do it is to start against Liverpool. We don't have any margin and we have to win the game."

Arteta said young midfielder Emile Smith Rowe had been troubled by "some discomfort in his hip" while away with the England Under-21 squad.

"We will speak with the doctors and the physios and see if he's available for training tomorrow," Arteta said.

Similar applies to Bukayo Saka, who pulled out of the senior England squad due to a hamstring problem but could come into contention for the weekend.

Liverpool versus Arsenal has thrown up some scintillating games in the past, and no fixture in Premier League history has seen more goals scored than the 166 they have shared in those battles.

Liverpool have scored 94 times in the Premier League rivalry, the most goals the Gunners have shipped against a single opponent in the competition.

Mikel Arteta declared himself "really disappointed" despite Arsenal fighting back from three goals down to claim 3-3 draw with West Ham United on Sunday.

The Gunners paid for a poor start at the London Stadium as they fell behind to early goals from Jesse Lingard, Jarrod Bowen and Tomas Soucek.

However, they reduced the deficit when Soucek was forced to put through his own net before the break, and it was game on when Craig Dawson did the same following the restart.

Alexandre Lacazette subsequently completed the turnaround with a header 10 minutes from time to earn the visitors a share of the spoils.

But, speaking after the game, manager Arteta could not hide his disappointment over a sloppy start that had given his side a mountain to climb.

He told Sky Sports: "I'm really disappointed because I cannot accept my team to play the way we did for certain periods in the first half because what I expect is the team to play the level we showed afterwards. 

"We played incredibly well, we should have scored six or seven goals, but we had two faces and the first face is about giving goals to the opponent and not doing what we have to do and that is not good enough.

"The first goal, it can happen. It's a really good combination, they do that, they play that channel well and have players in the box and scored a brilliant goal, it's fine. 

"The way we concede the second one is unacceptable, the third goal is unacceptable, and we still gave them one more – a throw-in and they hit the post.

"For the rest, [I liked] the attitude, the desire that we showed and the togetherness that we showed, because at 3-0 it's really difficult to do what we've done. 

"I have no doubts because we talked about it and I can see every day the energy and the cohesion the players have. We came really close to winning, I thought we deserved to win in the end, but the first part really worries me."

Arteta's opposite number David Moyes struck a more positive note, despite the fact his team threw away a sizeable lead.

"It was a really good game, a tough game, lots of goals. We played very well, especially in the opening 30 minutes, we were excellent," Moyes said.

"Unfortunately, we gave them a goal just before half-time from a deflection which I think the shot was going wide and it gave Arsenal a bit of a foot up. That made it more difficult. 

"We played very well for long periods; Arsenal played very well, but Arsenal are in good form at the minute and showing good things. 

"It wasn't a great result for us after going 3-0 up but it was still a good result. We've still kept ourselves moving along, it was a tough game for us and we showed that we're up there competing with the best teams."

The Hammers find themselves in the midst of a perhaps unexpected push for Champions League football this season, but missed a chance to go level on points with fourth-placed Chelsea.

Still, Moyes remained sanguine about his team's position given the manner in which they have exceeded all expectations thus far.

He added: "It's been a long time since we've finished above Arsenal in the league at West Ham, so we've done our best to make sure they can't catch us. 

"We're trying to stay in the top half of the league, I think at the start of the season if we'd said that we'd have said it's [going] good. But now we want more, now I'm greedy. 

"You should see the dressing room, they're devastated because they haven't taken all three points. It's a good sign for a manager, though."

Mikel Arteta has warned West Ham will know "how to hurt" his Arsenal team when the London rivals clash in the Premier League on Sunday. 

The fifth-placed Hammers sit seven points ahead of Arteta's toiling mid-table Arsenal with 10 games of the season remaining for both teams, as David Moyes continues to work wonders. 

Arsenal's best hope of qualifying for next season appears to be through the Europa League, which offers a place in the elite competition to the winners, and Slavia Prague await them in the quarter-finals. 

West Ham, however, can get there on merit through the domestic league, and three points at the London Stadium this weekend would bolster their top-four chances. 

Arteta and Moyes were appointed by their respective clubs in December 2019, and few would have foreseen West Ham being a step ahead of the Gunners 15 months down the line. 

Looking ahead to their tussle, Arteta said: "We know we will have a really tough game, they've been in great form. They've been really consistent, they know really well what to do and how to hurt opponents. I know David really well and I am sure he will prepare the match so it is a really difficult game for us." 

Arteta was asked whether West Ham's form has come as a surprise, to which he replied: "Not really. I think they have a really strong squad and they have a great manager and coaching staff. 

"They started the season with some doubts, but I know what David is capable of doing. 

"He gets the group together, they're working really hard for each other, they've recruited really well and you can start to see the things that David has done. Obviously they have a little bit more time during the week to prepare football matches and training, and I think they've been in great form and they're a really dangerous team." 

Arsenal muddled their way past Olympiacos in the Europa League last-16 on Thursday, with a 1-0 home defeat meaning the Gunners scraped through 3-2 on aggregate. As Arteta pointed out, West Ham have no European commitments this season, but it could be a different story next term.

Why are Arsenal still trailing in West Ham's wake?

West Ham were already ahead of Arsenal at the turn of the year and it will worry Arteta that the gap has grown since, yet in many aspects the teams have performed on a similar level in the Premier League.

Since January 1, the Hammers have a goals for-and-against of 19-11 in the competition, while Arsenal's shows as 21-10, and the 13.38 per cent shot conversion rate for West Ham is more or less identical to Arsenal's own (13.04).

West Ham have created 20 'big chances', to 16 by Arsenal, and both sides have 50 per cent conversion rates when it comes to those opportunities, which are defined by Opta as being "where a player should reasonably be expected to score".

Arsenal are on a par with their xG (expected goals rate) of 18.2 from 158 shots in 2021, scoring 18 non-penalty goals, while West Ham have taken 18 fewer shots and are similarly closely tracking their xG of 17.5, also scoring 18 times excluding spot-kicks.

Perhaps telling when it comes to judging the difference between the teams is the toll that errors are taking on Arsenal.

In 12 Premier League games this year, West Ham players have collectively made three errors leading to shots, none of which resulted in a goal, but Arsenal have made seven such errors and have conceded three goals as a direct consequence.

The Gunners' 2021 haul of 21 points from 12 games (W6 D3 L3) is bettered by West Ham, who have 25 points (W8 D1 L3) over the same period.

Indeed, only Manchester City (45 points from 16 games), Manchester United (27 points/14 games) and Leicester City (27 points/13 games) have taken more points than West Ham since the turn of the year.

Mikel Arteta saw Arsenal scrape through to the Europa League quarter-finals and warned the demise of Tottenham shows there are no formalities in knockout football.

Arsenal took charge of their last-16 tie with Olympiacos in Greece last week by opening up a 3-1 advantage, but a 1-0 defeat at Emirates Stadium on Thursday made for a rockier than expected route through to the final eight.

Gunners manager Arteta said Arsenal were "nowhere near" the required level and did not hide behind the fact his team avoided the same fate as their north London rivals, with Tottenham given a shock 3-0 hiding by Dinamo Zagreb to perish 3-2 on aggregate.

Speaking about Tottenham's miserable fate in the competition, Arteta – whose side lost three consecutive home matches in European competition for the first time in their history – said: "It shows as well the level of opposition, that people take for granted that you play against an opponent and you will go through, because of the name of the club that they represent.

"It is not like that, every team in Europe is difficult to beat."

Arteta only found solace in the fact Arsenal – who reached the quarter-finals of the competition for the fourth time in their last five campaigns – avoided Europa League elimination.

"If I have to evaluate the performance with what we've done today, with the ball in particular, then it's nowhere near the standards we have set for ourselves," Arteta said.

"We made it really difficult because we didn't have any stability when you give the amount of balls away that we have in the game.

"When that happens, you don't have the control to manage the tie in the way that we should have done and that's related to the amount of chances we missed again."

Tricky opposition will await Arsenal in the quarter-finals, with this competition particularly important given that winning it represents their only realistic path into next season's Champions League.

Premier League rivals Manchester United, Roma, Villarreal and Ajax are among the sides to have made the last eight.

Arsenal's dressing room was a quiet place after the game, goalkeeper Bernd Leno said.

Leno told Arsenal Media: "Everybody knows that it was not a good performance from us. We cannot change it anymore but the positive thing is that it was a warning. We need to be 100 per cent every game. If we play like today then we won't reach anything this season.

"This is probably the closest way to go to the Champions League and also to win a big European trophy so we need to step up."

Arteta, meanwhile, said Arsenal would not rush to pull Bukayo Saka out of the England squad for the World Cup qualifying games at the end of the month.

The young winger missed Thursday's fixture with a muscle injury but may have a chance of facing West Ham on Sunday, and if he misses out then Arsenal will consult with the England camp.

Martin Odegaard has everything to become the "complete player" according to Arsenal boss Mikel Arteta, who thinks the Norway international can add more goals to his game. 

Odegaard has impressed since joining the Gunners on loan from Real Madrid in January and followed his first goal for the club against Olympiacos last week with the equaliser in Sunday's 2-1 north London derby win over Tottenham. 

Ahead of the return clash with Olympiacos, where Arsenal hold a 3-1 advantage, Arteta warmly praised the 22-year-old playmaker. 

"He's getting better and better. I think his understanding of what we want is excellent," he told the media. 

"His work rate has been phenomenal. And then he's doing something which, in my opinion, he could improve a lot, which is getting in the opponents' box and being more decisive in the score line. 

"He's doing that. He's scored two goals, he's got some really important entrances in the zone and he looks really dangerous all the time. 

"It's something that if he adds that to his game, he becomes a real complete player." 

Odegaard's two goals in all competitions are more than any other Arsenal midfielder has managed since his debut, with only Bukayo Saka (19) having more than his 11 shots. 

He is also the best among his midfield colleagues over the same period in terms of chances created (13), while behind only Mohamed Elneny in terms of passing accuracy (92.9 versus 90.8 per cent), having played 468 more minutes than the Egypt international. 

"I think everybody has been really impressed with how quickly he adapted. How professional he is," Arteta said. 

"How quickly he adapted to try to engage with everybody at Colney [Arsenal's training ground] and then the performances he is putting in as well." 

Pierre Emerick-Aubameyang is back in contention to start after a disciplinary breach led to him being benched for the win against Spurs. 

Asked whether Aubameyang had been stripped of the Arsenal captaincy, Arteta replied: "That was dealt with on the day. It's been resolved in a really positive way and we move on." 

Fellow forward Gabriel Martinelli could get a chance for valuable first-time minutes against Olympiacos, having struggled for fitness and form this season. 

"If anything, it's my fault," Arteta said over the Brazilian youngster's lack of game time. "He's done everything perfect. He trains incredibly well every day. His attitude cannot be any better. 

"He's really disappointed that he's not playing more, obviously I have spoken to him. But he needs to be a little bit patient. 

"He had some minutes, he had some games as well and it’s true that the competition now for the front positions is very tough. He needs to be patient and he will get his chance." 

Saka, meanwhile, faces a late fitness test having made way at half-time in the game with Spurs due to a hamstring complaint.

Matteo Guendouzi insists his Arsenal career is not over and he wants to fight his way back into Mikel Arteta's plans next season.

Guendouzi, 21, has been on loan with Hertha Berlin since last October where he has made 19 appearances for the Bundesliga club.

The French midfielder was a regular starter with the Gunners under previous boss Unai Emery but failed to make an appearance for Arteta's side in the opening weeks of the season prior to securing a temporary move away.

When asked if his Arsenal career was over due to an apparently strained relationship with Arteta, Guendouzi was emphatic in his response.

"No, not at all," he told France Football.

"I am focused on my season at Hertha Berlin. Then, we will make a point with my agent and the people of the club to sit down and discuss the future. I am still an Arsenal player."

Guendouzi joined Arsenal from Lorient in 2018 and has made 57 Premier League appearances for the Gunners, registering just one assist and no goals in the competition.

In those games he attempted a total of 75 tackles, the third-most among Arsenal players across 2018-19 and 2019-20, while his 263 duel wins over the same period was only bettered by four of his team-mates.

His contract with Arsenal expires at the end of next season and he acknowledged his long-term future will be at stake when he returns to the Gunners.

"This summer will be a decisive moment," he added.

"Could I come back to the club with Mikel Arteta on the bench as coach? Yes, of course. I will be with Arsenal for another year.

"I am here to move forward. When I played for Arsenal, I have always given everything for this club, for these fans, for the team, for the staff. I will work hard for the jersey as usual."

Arsenal manager Mikel Arteta said the Gunners are still eyeing a top-four finish in pursuit of Champions League football following their Premier League win over rivals Tottenham in the north London derby.

Alexandre Lacazette's second-half penalty helped Arsenal beat Tottenham 2-1 on Sunday as Arteta celebrated his first Premier League win over Spurs since taking charge.

Erik Lamela's stunning rabona goal put Tottenham ahead just past the half-hour mark before Martin Odegaard equalised on the stroke of half-time.

Tottenham midfielder Lamela went from hero to villain – sent off in the 76th minute after Lacazette completed the turnaround 12 minutes earlier.

Arsenal are 10th in the Premier League standings – 10 points adrift of the top four with 10 rounds remaining – but Arteta is not giving up on Champions League qualification.

"Up until mathematically it's impossible we're going to believe and we're going to give it a go that is for sure," Arteta, who replaced Unai Emery in December 2019, said in his post-match news conference.

"We know that we're going to have to be extremely consistent, to have any chance in the last two or three matches to be close to that.

"But we're going to give it a go and we're going to keep trying, going game-by-game."

Arsenal have not featured in the Champions League since 2016-17 – the Gunners consigned to the Europa League for the past four seasons.

The Gunners are unbeaten in their last 10 Premier League home games against Spurs (W6 D4), while Arteta is the third consecutive Arsenal boss to win his first home league meeting with Tottenham following Arsene Wenger and Emery.

Since losing his first London derby at Emirates Stadium in the Premier League (2-1 against Chelsea in December 2019), Arteta is unbeaten in his last five such games, picking up four victories (D1).

All eyes were on the Emirates Stadium on Sunday for the north London derby and there was a lot of comforting familiarity on display.

A red card, Erik Lamela attempting a rabona (and scoring it!) instead of using his right foot, and, of course, Spurs throwing away a lead.

Elsewhere, Manchester United remained on course to finish second as they ensured David Moyes' continues to dread returning to his former employers, while Sheffield United's first game since Chris Wilder's exit arguably proved just how good the Yorkshireman was as manager.

There was also a potentially vital win near the bottom of the table for Brighton and Hove Albion, and we have taken a look at all the best Opta facts from those games.

Arsenal 2-1 Tottenham: Spurs surrender once again in a north London derby

Lamela's opening goal will be shown in north London derby highlight reels for years – his rabona finish was so good, so audacious.

But even with that being the opening goal, it never really looked like being decisive, so underwhelming were Spurs otherwise from an attacking perspective – the fact they went on to lose meant they have now dropped 45 points from winning positions against Arsenal in the Premier League, the most of any team against a specific opponent in the competition.

After Martin Odegaard levelled, becoming just the fourth Gunners player to score in his first top-flight north London derby, Alexandre Lacazette's second-half penalty secured Arsenal the points.

It was Spurs' ninth league defeat of the season, the joint-most Jose Mourinho has ever suffered in a single season, and Lamela's sending off certainly did not help their situation.

In collecting two bookings, he became only the fifth substitute in Premier League history to score and be sent off in the same game.

His goal will be the enduring moment from the match, but in the grand scheme it was meaningless for a Spurs side in increasing danger of missing out on the top four.

Manchester United 1-0 West Ham: Moyes' Old Trafford misery continues

It was not an occasion for the neutral at Old Trafford as Man United scraped an unconvincing win thanks to an own goal by Craig Dawson.

The defeat means only Harry Redknapp (15) has managed more Premier League games away to United without winning than former Red Devils boss Moyes (14 – four draws, 10 losses).

The Hammers' difficulties in front of goal were partly to blame as none of their seven attempts were on target, the highest number of shots they have had in a league game without a single accurate once since August 2013 (nine shots).

On the flipside, Man United kept a fourth straight Premier League clean sheet for the first time under Ole Gunnar Solskjaer, with the club last achieving that feat in January 2018 under Mourinho.

They have also lost just one of their previous 23 league outings having suffered three losses in their opening six games this term.

Leicester City 5-0 Sheffield United: Blades suffer bruising defeat as they venture into the Wilder-less wilderness

Less than 24 hours on from confirmation of Wilder's "mutual" departure as Blades manager, many were likely left wondering why the club did not fight harder to keep him.

While seemingly doomed for relegation anyway, Wilder retained significant respect for the job he presided over at Bramall Lane, and Sunday's result showed why.

With interim boss Paul Heckingbottom taking over for the first time, he has already shipped five goals in a single game as many times as Wilder did in 227 matches (a 5-4 defeat to Fulham in 2017). Their former manager was never beaten by more than a three-goal margin.

Heckingbottom also became only the third manager in Premier League history to lose by five or more goals in his first game, but this should not take credit away from Brendan Rodgers' ferocious Foxes.

Kelechi Iheanacho scored his first hat-trick and also netted in three successive top-flight games for the first time. Jamie Vardy set up two of those goals and in doing so became only the sixth player to register 100 or more goal involvements in the Premier League after turning 30.

Those to achieve this before him were Teddy Sheringham, Frank Lampard, Ian Wright, Alan Shearer and Gianfranco Zola – esteemed company indeed.

Southampton 1-2 Brighton and Hove Albion: Seagulls remember their shooting boots as Saints sink

Much has been said and written about Brighton's woes in front of goal this term, but they got the job done here.

Their 2-1 win at St Mary's is only the second time in 2021 that they have scored twice or more in a single Premier League game – the other instance was their 3-3 draw with Wolves in their first match of the year.

This was their 11th outing since.

The win took Graham Potter's men three points clear of the relegation zone and just four behind Saints, who are in a difficult spot.

It is 10 defeats in the past 12 Premier League games now for Southampton, with Ralph Hasenhuttl coming under increasing pressure – their previous 10 losses came across a 38-match spell.

Arsenal manager Mikel Arteta insisted there were no hard feelings on his part towards Pierre-Emerick Aubameyang after the Gunners battled to north London derby glory without their captain.

Martin Odegaard's first Premier League goal for Arsenal and a second-half penalty from Alexandre Lacazette gave Arteta's men a 2-1 win over Tottenham, who turned in a meek display either side of a phenomenal rabona opener from Erik Lamela, who was later sent off.

Lacazette only started because Aubameyang fell foul of Arsenal's pre-match protocols, with the Gabon forward an unused substitute at Emirates Stadium.

Nevertheless, Arteta said the problem – reported to be a time-keeping issue – is already something to be forgotten about.

"He is an incredible guy and one of the most important players in the team," he told Sky Sports.

"He is our captain and these things happen. We have lots going on in our lives and people finding it hard with the restrictions.

"I will never tell anything that happens in the dressing room."

Arsenal failed to convince during the closing stages as Harry Kane had a header disallowed for offside and fired a free-kick against the post.

"Going 1-0 down the way we were playing was disappointing and worst-case scenario against a team like Spurs. But we kept playing and deserve the win," Arteta said,

"The last 10 minutes we did not manage the game and we need to improve as a team. We relied on luck. With the way we played we should have seen it out comfortably."

Arteta, who is the third consecutive Arsenal boss to win his first home league meeting with Spurs, following Arsene Wenger and Unai Emery, added: "We had some really strong performances today.

"You could see the energy they were playing with."It is about how you react. This team have the reaction in them to not give up. We kept playing and generating chances and got rewarded."
