Hakim Ziyech and Mateo Kovacic could be doubts for the EFL Cup final this weekend after hobbling out of Chelsea's Champions League meeting with Lille. 

Kovacic sustained an injury shortly after the restart in the last 16 first leg at Stamford Bridge on Tuesday and was replaced by Ruben Loftus-Cheek in the 51st minute.

Ziyech, who has scored in each of his past three Premier League appearances and set up Kai Havertz for the opener against Lille, appeared to sustain an ankle injury. Saul Niguez was sent on in his place in the 60th minute. 

Thomas Tuchel will no doubt hope the pair are able to recover in time to feature against Liverpool at Wembley on Sunday, with Chelsea chasing more silverware after their Club World Cup triumph earlier this month.

Romelu Lukaku was dropped to the bench by Thomas Tuchel for Chelsea's Champions League last-16 meeting with Lille on Tuesday. 

Belgium international Lukaku was a peripheral figure during Saturday's 1-0 victory over Crystal Palace at Selhurst Park and was named among the substitutes for the first leg against Lille at Stamford Bridge. 

He was replaced in the line-up by Cesar Azpilicueta, with Kai Havertz handed the central striking role and flanked by Hakim Ziyech and Christian Pulisic. 

Lukaku paid the price for a historically quiet game display against Palace, which saw him manage just seven touches – one of which was from kick-off. It was the fewest touches by a player who featured for 90+ minutes in a single Premier League game since 2003-04, when Opta has the data available from.  

Tuchel made two other changes to his team, with Marcos Alonso replacing Malang Sarr and Mateo Kovacic chosen ahead of Jorginho. 

Chelsea and Senegal goalkeeper Edouard Mendy is relishing a huge week for the Stamford Bridge outfit, saying he will have time to celebrate his recent trophy wins at the end of the season.

Mendy has enjoyed another strong campaign, lifting the Club World Cup with Thomas Tuchel's team after starring in his nation's first major trophy success at the Africa Cup of Nations.

He kept four clean sheets and was named the tournament's best goalkeeper as Senegal lifted the trophy.

But with the London outfit facing a crucial week on two fronts, hosting Lille in the Champions League last 16 on Tuesday before facing Liverpool in Sunday's EFL Cup final, the 29-year-old says he is simply taking each game as it comes without any time to celebrate just yet.

"A lot of good things have happened in the last weeks," Mendy said ahead of Chelsea's first-leg clash with Lille. "I am very happy and proud of my success with the national team and Chelsea.

"I don't have time to celebrate, because we have a lot of big games in the coming weeks, so I am just focused on the next game. I will have time to celebrate at the end of the season.

"It's an important week but like I said, when you play for Chelsea you play for this kind of week, with finals and big games.

"We just [have to] focus on ourselves and what we have done well this season. We don't need to do something new, just rely on our work and our game."

Mendy, who has kept nine clean sheets in 21 league appearances for Chelsea in the Premier League this season, was also keen to praise teammate Kepa Arrizabalaga, who deputised ably when he travelled to Africa.

"My relationship with Kepa is good since I came here, we have a good relationship on and off the pitch," he said.

"When you play for Chelsea, you have competition in every position, so you have to give your best and play at your highest level to be in the team at the weekend."

Mendy also warned of the challenge posed by Lille ahead of the Ligue 1 holders' trip to London, as Chelsea try to retain their Champions League title.

He added: "When it's the Champions League and this stage of the competition, there are no easy draws.

"Lille are a very good team. They've struggled a bit more this season in the league [sitting 11th in Ligue 1 after 25 games] but it's always difficult to be reigning champions.

"They will give everything to make it hard for us and get a result. It's up to us to be wary of that and play our best football."

Chelsea are the first Champions League holders to progress to the knockout stages without winning their group since Real Madrid in 2017-18, but the Spanish side did go on to retain their title that season.

Champions League holders Chelsea get their knockout campaign started on Tuesday as the defence of their crown enters an altogether more challenging stage.

Thomas Tuchel's men may feel they have dodged a bullet or two by getting this draw, with their next opponents Lille struggling to match the highs of their Ligue 1 title victory from last season in 2021-22.

Tuesday's other encounter sees Juventus travel to Villarreal, with Massimiliano Allegri looking to improve on the knockout exploits of Maurizio Sarri and Andrea Pirlo before him.

Here, Stats Perform delves into the Opta data to pick out the key statistical narratives and subplots ahead of Tuesday's games.

Chelsea v Lille

Much of the attention at Stamford Bridge will be on Romelu Lukaku, whether the Belgian plays or not.

The big-money signing's struggles this season have been well-publicised, but he hit a new low on Saturday as he touched the ball just seven times in the win over Crystal Palace – that is the fewest by any player to feature for 90 minutes in a single Premier League game since at least 2003-04.

On the other side of the contest is a striker aiming to emulate Lionel Messi. Jonathan David may not have scored a Ligue 1 goal since December but the talented Canadian impressed in the second half of the group stage.

He scored one goal in each of his last three appearances in the competitions, meaning if he scores on Tuesday he will be the second-youngest (22 years, 39 days) non-European to score in four successive Champions League games after Messi (21y, 155d in November 2008).

That is not to say Lille are a high-scoring side. Many will be wondering who let Les Dogues out of Group G, given their haul of seven makes them the lowest-scoring group winners since Leicester City and Atletico Madrid (seven each) in 2016-17. In fact, no team from that section scored more than eight.

The omens are, perhaps unsurprisingly, overwhelmingly in Chelsea's favour here. Only Manchester City (15) and Bayern Munich (14) have won more Champions League games than the holders since the start of last season, while Lille are appearing at this stage for just the second time ever.

Further to that, Tuchel boasts a fine record in Champions League knockout ties, having progressed from/won (including finals) eight of his previous 11 (73 per cent), a success rate bettered by only three managers (minimum 10 knockout ties): Vicente del Bosque (80 per cent - 8/10), Jupp Heynckes (86 per cent - 12/14) and Zinedine Zidane (88 per cent - 14/16).

Villarreal v Juventus

Sarri and then Pirlo were both tasked with establishing a new era at Juventus, but when Allegri returned after a two-year break in pre-season, he picked up the pieces of a side that had regressed significantly.

There remain plenty who feel Allegri never should have been re-hired, but this tie at least gives him an opportunity to point to a degree of progress – at least in the context of the Champions League.

After all, neither Sarri nor Pirlo got beyond the last 16. Allegri, on the other hand, was only eliminated at this stage once in five seasons, and that was to Pep Guardiola's excellent Bayern side.

His counterpart on Tuesday, Unai Emery, has something of a point to prove as well, but his has more to do with his own personal record.

While something of a specialist at Europa League level, having won the competition four times including last season, he has won only one of six knockout games in the Champions League.

Much of Emery's hope will be pinned on Arnaut Danjuma.

The Dutchman – who recently returned from two months out and scored a hat-trick at the weekend – had a hand in five goals in the group stage, which is already a joint-club record for the club in the competition.

By no means are the Yellow Submarine a one-man team, however. Young winger Yeremi Pino caught the eye in the group and is plotting to become only the fourth Spanish teenager to score in the knockout stages of the Champions League after Bojan, Cesc Fabregas and Raul.

Mauricio Pochettino's future at Paris Saint-Germain is unclear amid rumblings that he wants out.

Manchester United have been linked with the ex-Tottenham manager, who took over at PSG in January last year.

The Red Devils dismissed Ole Gunnar Solskjaer in November, with Ralf Rangnick taking over on an interim basis.

TOP STORY – LOS BLANCOS KEEN ON POCHETTINO

Real Madrid are set to rival Manchester United to land Pochettino this off-season, claims the Daily Mail.

The Red Devils are understood to be circling for the Argentine, who is reportedly unhappy at Paris Saint-Germain.

But the report claims Madrid have doubts over current boss Carlo Ancelotti's future and believe that Pochettino is obtainable in the off-season.

ROUND-UP

- Manchester City's Portugal midfielder Bernardo Silva is dreaming of a switch to join Real Madrid, claims Calciomercato.

- Calciomercato also reports that Inter are monitoring Gabriel Jesus' status at City, with a view to bolstering their attack.

- Nicolo Schira reports that Atalanta are keen to move for Torino's Italy international striker Andrea Belotti in the off-season when he is a free agent.

- TuttoMercatoWeb claims Arsenal, Newcastle United, Borussia Dortmund and Inter are all in the race to sign Lille's Canadian forward Jonathan David.

- GiveMeSport claims Liverpool are "seriously interested" in West Ham United's Jarrod Bowen.

- Roma are keen on signing Barcelona's USA international defender Sergino Dest according to Fichajes.

Thomas Tuchel has moved to manage expectations of Chelsea ahead of a crucial week that will see them return to Champions League action and contest the EFL Cup final.

Chelsea played their first Premier League game in nearly a month on Saturday, beating Crystal Palace at Selhurst Park thanks to a late Hakim Ziyech goal.

In the intervening month, Chelsea progressed in the FA Cup and won the Club World Cup for the first time, defeating Palmeiras in extra-time.

Tuchel complained about Chelsea's packed schedule after beating Palace, acknowledging his team looked "a bit drained and exhausted".

But they have little time for rest with Lille visiting Stamford Bridge in the first leg of their Champions League last-16 tie on Tuesday and then a showdown with Liverpool at Wembley on Sunday, as Chelsea look to claim a second trophy of the season.

Looking forward to an important week, Tuchel tried to ease the pressure.

"I think it is very important for us in this moment to be realistic and not over-expect from us," he told reporters.

"Also accept games against teams in mid-table or the lower end of the table can become difficult games. Once we accept that, it is the first step to feel a certain freedom and to become better, that we don't over-expect.

"We should not expect too much about how big others see us and if we are the favourites against Lille, just accept it is a phase where things feel a bit tight and a bit more difficult than in other times.

"We will accept it and this is the situation for the match on Tuesday. First of all we play at Stamford Bridge and we are confident to have a good performance because we deliver on a high level in knockout matches, cup matches, Champions League matches."

Despite his previous comments about fixture congestion, Tuchel is not especially worried about the tight turnaround being an issue before facing French champions Lille.

"I think that Saturday to Tuesday evening for us as a home game and playing in London should not be a problem," he added.

"Sometimes it can cause a big advantage if there is a tight schedule, but we will be ready to fight with Lille on an okay level so that should not be decisive."

Lille forward Timothy Weah hopes to play for Milan in the future because it is part of his "family history". 

Weah's father George spent five seasons at Milan in the 1990s, winning two Serie A titles and becoming the first – and still only – African player to win the Ballon d'Or. 

The 21-year-old would love to emulate his dad and represent the Rossoneri, though he insists his primary concern is to impress for Ligue 1 champions Lille. 

"Of course I am focused on Lille, but it has always been my ambition to one day play in a great league like Serie A and, in particular, for a big club like Milan, which is part of my family history after all," he told La Gazzetta dello Sport's Sportweek. 

"[My dad] never talks about it openly, but when I was a child, there was the idea of playing for the Rossoneri's youth teams. Things went differently, but maybe I'll arrive at Milan anyway. 

"Things go so fast in football, and you never know." 

United States international Weah has scored just five goals in 64 appearances in all competitions for Lille since arriving from Paris Saint-Germain – another of his father's former clubs – in June 2019. 

Weah has failed to score in Ligue 1 this season, despite making 19 appearances and starting 10 games. He has supplied three assists, but has only had three efforts on target.

His Lille team-mate Jonathan Bamba is the only forward to have made more Ligue 1 starts (18) without finding the net in 2021-22.

Chelsea have been crowned European and world champions since Thomas Tuchel's appointment just over 12 months ago.

The Blues, however, finished fourth in the Premier League last season.

Chelsea are third this term but 16 points behind leaders Manchester City with a game in hand, and it seems recruitment is in the offing.

TOP STORY – BLUES SET TO SPLASH THE CASH

Chelsea are set for an off-season transfer splash as they prepare to back Tuchel fresh from their Club World Cup triumph, according to The Telegraph, 

The Blues have their sights firmly set on signing long-term target Jules Kounde from Sevilla as a priority in the upcoming off-season.

Chelsea are also interested in West Ham United's England international Declan Rice and Monaco's 22-year-old French midfielder Aurelien Tchouameni.

ROUND-UP

- Football London reports Arsenal are plotting a move for Chelsea forward Armando Broja, who is currently on loan at Southampton. The Gunners are short on attacking options after Pierre-Emerick Aubameyang's exit and with Alexandre Lacazette and Eddie Nketiah running down contracts.

- Fichajes also claims that Arsenal are interested in Milan forward Rafael Leao, along with Newcastle United.

- Barcelona are trying to agree new deals with star young pair Gavi and Ronald Araujo amid interest from Liverpool and Manchester United, reports ESPN.

- Juventus are willing to listen to offers for Adrien Rabiot and Alex Sandro according to La Gazzetta dello Sport.

- Fichajes claims that West Ham want to sign Lille defender Sven Botman, Villarreal left-back Pervis Estupinan and Real Sociedad centre-back Robin Le Normand.

Manchester United remain on the lookout for a full-time manager, three months on from sacking Ole Gunnar Solskjaer.

Ralf Rangnick has taken interim charge until at least the end of the campaign, but some mixed results have hampered his hopes of landing the job permanently.

A number of names have been linked with one of football's most prestigious positions, though one candidate is seemingly favoured by the players.

TOP STORY – UNITED STARS FAVOUR POCH APPOINTMENT

Mauricio Pochettino remains the favourite to succeed Solskjaer as United's next permanent boss and, according to The Express, that is an appointment that will go down well.

The Red Devils' first-team stars are said to have made clear that Pochettino, who is under pressure a year into his time with Paris Saint-Germain, is their preferred option.

Ajax boss Erik Ten Hag is another candidate to lead United forward from next season, but there are concerns over his lack of experience in English football.

ROUND-UP

- While there is uncertainty over who will be in charge at United next season, the Premier League heavyweights are pushing ahead with transfer plans. Sport1 reports that Borussia Dortmund defender Manuel Akanji is one of those being targeted.

- Memphis Depay could be on his way out of Barcelona less than a year after arriving at Camp Nou. Sport claims that Barca have other attacking options in mind, with Dortmund superstar Erling Haaland still on their radar.

- Inter remain in talks with Ivan Perisic over a new contract at San Siro. According to Nicolo Schira, the Croatia international is close to putting pen to paper on an extension that will run through until July 2024.

- Calciomercato reports that Milan are planning talks with the representatives of Lille centre-back Sven Botman. The highly rated defender has been touted as a target for numerous clubs across Europe, most notably Newcastle United.

- Chelsea have not given up hope of tying Antonio Rudiger down to a new deal, according to Goal. It is claimed that the Germany international has been offered close to £200,000 a week to turn down interest from Real Madrid and PSG.

Kylian Mbappe has denied he has already decided to join Real Madrid at the end of the season.

The Paris Saint-Germain striker spoke about what the future might hold after his fine strike put the seal on a 5-1 win over Lille in Ligue 1 on Sunday.

German newspaper Bild recently reported Mbappe and Madrid had reached an agreement that would see the France international move to the Santiago Bernabeu.

Mbappe's contract at PSG is due to expire at the end of the season, and although the French club are keen for him to sign an extension, it is unclear whether that is under consideration. Madrid's interest is no secret, after they tried to sign Mbappe in August.

The 23-year-old Mbappe would be able to leave on a free transfer, but the fact PSG have drawn Madrid in the Champions League last-16 stage appears to have held up any direct talks.

The European giants will go head to head in Paris on February 15 and in Madrid on March 9, with Mbappe steadfast that he wants to help PSG win that tie.

Asked whether he has already decided his next step, or whether the Madrid game could influence his choice of club, Mbappe told Amazon Prime Sport Video: "No, my decision hasn't been taken.

"The fact we play against Real Madrid, that changes a lot of things. Even if I'm free to do what I want at the moment, I'm not going to go and talk with the opposition or do this sort of thing.

"I'm concentrated on winning against Real Madrid, to try to make the difference. And after that, we'll see what will happen."

Mbappe and Lionel Messi are striking up a strong on-pitch relationship, with Messi looking to find Mbappe 12 times during the win at Lille and Mbappe playing eight passes to the seven-time Ballon d'Or winner, only seeking out Marco Verratti more often (10 passes).

Messi scored his second Ligue 1 goal and his first since November, ending a six-game drought in the competition, delivering a performance that might cause concern in Madrid.

He also played a more central role than has often been the case, and Mbappe, who took his league haul to a team-high 11 goals for the campaign, liked what he saw from the former Barcelona star.

"I'm not a coach. But Leo, he's a player who needs to touch the ball, to feel the game and the match, to be involved too," Mbappe said.

"So I think it's a good position for him. He's free, he can move, pick up the ball, he is close to the goal. I think that for him, it's a good position."

Mbappe is starting on the left of a front three, with the only worry from Sunday's match being that Angel Di Maria, who began on the right, was substituted shortly before half-time, having seemed uncomfortable.

Neymar will soon be back from injury, and Mbappe said: "We will also have to configure with Ney, because he is also an important player. He changes our team, so we'll see when he comes back. We hope he comes back as soon as possible."

Lionel Messi scored his first Ligue 1 goal since November as Paris Saint-Germain routed last season's champions Lille 5-1 at Stade Pierre Mauroy.

Ending a six-game drought in the competition, Messi produced a cunning finish for PSG's third goal, with Danilo Pereira netting twice and Presnel Kimpembe also on target before Kylian Mbappe's sumptuous 20-yard strike rounded off the scoring.

The Parisians' 1-0 defeat to Lille in April last season was a pivotal result in the title race, with Lille finishing a point clear of Mauricio Pochettino's team to be crowned champions.

Sunday night's result keeps Lille mired in mid-table this time around, while PSG hold a 13-point lead over second-placed Marseille.

The visitors took a 10th-minute lead when goalkeeper Ivo Grbic fumbled a cross from the left whipped in by Nuno Mendes, spilling the ball and allowing Pereira to poke home.

Messi curled wide from 20 yards for PSG, but it was Lille who snatched the game's second goal, Sven Botman beating Gianluigi Donnarumma with a bouncing shot from 10 yards after Hatem Ben Arfa made a nuisance of himself, wriggling into the box from the left flank.

PSG restored their lead in the 32nd minute when Messi's corner from the right was prodded in at the far post by Kimpembe, for the defender's first league goal this season.

Messi had his goal six minutes later when he collected the leftovers from an Mbappe charge, spotting a gap between Lille defenders and darting through before cheekily chipping Gbric.

PSG's fourth after 51 minutes saw Pereira's 25-yard strike deflect off Amadou Onana and deceive Grbic. 

There was then little the goalkeeper could do about Mbappe's classy finish, as the France star, stepping in from the left, curled the ball into the far-right corner for the visitors' crowning glory.

Paris Saint-Germain head coach Mauricio Pochettino says finding the right balance will be key when his side face Lille on Sunday.

The Ligue 1 leaders travel to Stade Pierre-Mauroy aiming to regain their 13-point cushion at the summit of the French top-flight.

PSG are also seeking a response from their Coupe de France exit at the hands of Nice time out, when on-loan goalkeeper Marcin Bulka's penalty shoot-out heroics denied his parent club.

Reigning champions Lille, who find themselves in 11th place following a disappointing attempt at a title defence, have only lost once in their last four home games against Pochettino's side.

And though PSG are nevertheless favourites to take three points, Pochettino knows that his team cannot go full-throttle in attack in every match, even with such supreme talent at their disposal.

"We are moving forward step by step, match by match," he said.

"Of course, we are disappointed with the last result and with the elimination from the Coupe de France on penalties against Nice. We lost and we have to accept it. 

"We want to get back into the swing of things, so playing a good team like Lille is a positive thing. 

"All the teams that play against Paris Saint-Germain are very motivated, so it will be complicated. 

"We will have to find the right balance between defending well, playing and being effective; that will be the key. 

"It will be important because there are three points at stake, and we want to keep our lead over our rivals. We have to move forward, we have several objectives ahead of us that require a lot of energy."

Neymar celebrated his 30th birthday on Saturday, yet the Brazil star is still recovering from injury, while Sergio Ramos, Mauro Icardi and Georginio Wijnaldum will all miss the trip, with Keylor Navas a doubt.

Declan Rice has long since been linked with a move to Manchester United and the Red Devils' pursuit is reportedly set to step up a notch.

England midfielder Rice is a man seemingly in demand, even though suitors will likely have to stump up a minimum of £100million to land him.

With Manchester City and Chelsea also said to be interested, United are aiming to be at the front of the queue for his signature.

TOP STORY – RICE A MAN IN DEMAND

Manchester United are likely to wait until a permanent manager is in place to make their moves in the market, with Ralf Rangnick remaining in charge on a temporary basis until the end of the campaign.

But the Mirror reports that Rice remains high on their list of priorities with United aiming to overhaul their midfield ahead of next season.

Leeds United's Kalvin Phillips and RB Leipzig's Amadou Haidara are apparently also high on United's shortlist of targets.

ROUND-UP

- The Red Devils are set to be busy in the close-season with Barcelona's highly rated centre-back Ronald Araujo on their radar, according to the Mirror. The defender, who is entering the final 18 months of his contract, is thought to be attracting interest from Manchester City too.

- Aston Villa right-back Matty Cash has emerged as a transfer target for LaLiga giants Atletico Madrid, according to Fabrizio Romano. Atleti allowed Kieran Trippier to join Newcastle United in January.

- The Sun reported that Arsenal are set to complete a triple swoop for Everton's Dominic Calvert-Lewin, Alexander Isak of Real Sociedad and Wolves' Ruben Neves in the next transfer window.

- Lille centre-back Sven Botman is still high on Newcastle United's radar despite a deal not being able to be struck during the last window, says the Athletic.

- Victor Osimhen remains a top target for Tottenham, writes Football Insider. Spurs will need to stump up around £60m to land the Napoli striker.

When the next transfer window opens, Erling Haaland's future will be a hot topic.

The 21-year-old striker has two years remaining on his Borussia Dortmund contract.

But there is a £65million (€75m) release clause that enables him to talk to clubs who can meet that valuation from this off-season.

TOP STORY - CITY READY TO RAMP UP HAALAND ADVANCES

El Chiringuito claim that Real Madrid's interest in signing Haaland has waned as they focus on landing Kylian Mbappe from Paris Saint-Germain.

Madrid have been heavily linked with Haaland once his release clause becomes active, along with Barcelona, PSG, Chelsea, Manchester United and Manchester City.

City "will do what they can" to persuade Borussia Dortmund's Erling Haaland to join them in the off-season despite believing they are not front-runners, reports The Athletic.

ROUND-UP

- ESPN claims that Manchester United have asked Paul Pogba to delay a decision on his future until they have appointed a permanent manager. Pogba's contract is up in June and he has been linked with PSG and Juventus.

- Chelsea have shortlisted West Ham United's Declan Rice, Sevilla's Jules Kounde and Monaco's Aurelien Tchouameni as off-season targets, claims The Athletic.

- Newcastle United plan to re-ignite their interest in Lille's 22-year-old defender Sven Botman, who is worth £35m (€42m) according to The Mirror.

- Arsenal turned down approaches from Newcastle and Crystal Palace for Eddie Nketiah in the closing days of the January transfer window reports Fabrizio Romano. Nketiah has six months remaining on his Gunners deal and could sign a pre-contract elsewhere.

Ousmane Dembele's future at Barcelona has been uncertain for months.

The 24-year-old has stalled on a new deal with the Catalans.

Dembele has attracted interest from several top clubs, meaning his signature looms for deadline day.

TOP STORY – MAN UTD TO HIJACK PSG'S DEMBELE MOVE

Manchester United are set to make a deadline-day move for Barcelona's Dembele, according to Footmercato.

The Red Devils could hijack Paris Saint-Germain's plans, with the Ligue 1 club having already verbally agreed to a deal with the French winger.

United are ready to move, with Anthony Martial loaned out and Donny van de Beek and Jesse Lingard also set to exit.

ROUND-UP

- Arsenal outcast Pierre-Emerick Aubameyang has agreed to a deal to join Barcelona, according to Sport, but Dembele must exit the Catalans to enable the move to be completed.

- Real Madrid have opted against a January move for Monaco's Aurelien Tchouameni, claims Diario Sport, due to their €80m asking price.

- Talksport claims that Tottenham's Giovani Lo Celso will join Spanish club Villarreal on loan for the rest of the season. Lyon were also interested in the Argentina international.

- Portuguese midfielder Renato Sanches has opted against a €25 million move from Lille to Milan, according to Calciomercato.

- Newcastle United's January spending is not over as the club eyes deadline-day deals for Aston Villa's Matt Targett and Arsenal's Eddie Nketiah, reports The Telegraph.
