There have been only 15 Premier League matchweeks since the start of the season, but plenty has changed.

Arsenal, rather than Liverpool, look the biggest threat to Manchester City's title defence, while Newcastle United are third ahead of the campaign resuming on Monday.

With the January transfer window also just around the corner, it is time to revisit Stats Perform's ranking of the top 20 most valuable Premier League players, first published back in July.

Inspired by Bill Simmons' NBA trade value list for The Ringer, this is not a ranking of the 20 best Premier League players but perhaps the 20 most difficult to sign.

The following factors have all been considered: how important these players are to their clubs, how replaceable they are, how proven they are, how likely they are to be sold now or in the near future, and how much they would cost if they were to move, influenced by ages and contract situations.

There have been some significant moves since the previous edition...

1. Phil Foden – Manchester City (July rank: 2)

Foden has gone from strength to strength at City this season, excelled for England at the World Cup and, in October, signed a new contract. There is no amount of money in the world that could convince City to sell the 22-year-old.

2. Reece James – Chelsea (12)

James is perhaps Chelsea's equivalent of Foden, their most talented academy graduate and still only 23. He was in excellent form to start the season before sustaining an injury that ruled him out of the World Cup. His big leap is more due to Chelsea's continued commitment to success under new owner Todd Boehly.

3. Erling Haaland – Manchester City (3)

There will always be speculation around Haaland's future, the existence or otherwise of any clauses in his contract and the suggestion he might hope to play for a Real Madrid. But he is not going anywhere just yet and is surely the form player in European football this season.

4. Kevin De Bruyne – Manchester City (4)

De Bruyne is now 31, making him by some distance the oldest player in the top five, and endured a miserable World Cup. However, the signing of Haaland has allowed De Bruyne to again showcase just how good he can be, thriving playing alongside a dead-eyed finisher.

5. Bukayo Saka – Arsenal (14)

The biggest star of Arsenal's resurgence has been Saka, who then also starred at the World Cup and was highly unfortunate to exit the tournament alongside his England team-mates. There will always be suspicions Arsenal will move on their best players eventually, but they are proving right now he does not need to leave to succeed.

6. Bruno Guimaraes – Newcastle United (15)

Another big jump takes Guimaraes up the rankings, having impressively built on his superb start to his Premier League career. Now an all-action number six, rather than a goal-getting box-to-box star, he has been linked to Real Madrid but appears committed to Newcastle, whose rapid progress should keep him happy.

7. Bruno Fernandes – Manchester United (7)

The Premier League's other big-name Bruno only narrowly trails Guimaraes, with Fernandes set to be United's undisputed main man following Cristiano Ronaldo's departure. It would likely only be United's failure to secure Champions League football that would see Fernandes consider his future.

8. Virgil van Dijk – Liverpool (5)

Four of the five Liverpool players on this list have fallen, although Van Dijk remains the Premier League's most valuable centre-back. Whether he is still the division's best at his position could be up for debate, however, with the Reds far less steady in defence this season.

9. Mohamed Salah – Liverpool (6)

Van Dijk's Liverpool team-mate Salah is 30 now and has slipped below his lofty standards at least in league play, scoring only six times so far this season. Liverpool will not rush to move on the winger, but they will be in trouble if this proves to be a sustained decline.

10. Harry Kane – Tottenham (10)

Spurs have seemingly guarded off interest in Kane from elsewhere, with potential suitors City happy with Haaland, but the arrival of Richarlison might also make them less reliant on the England captain than in previous years. He has still scored 12 league goals this season.

11. Trent Alexander-Arnold – Liverpool (1)

Alexander-Arnold has long had detractors outside of Anfield – including Gareth Southgate, who seemingly considers him England's fourth-best right-back. But this is the first time the 24-year-old's Liverpool performances have really been scrutinised. Regardless of Liverpool's stance, rival clubs would likely look elsewhere for a more complete full-back option.

12. Ederson – Manchester City (10)

Ederson slips only due to the number of top players on the rise. He is the most valuable goalkeeper in the Premier League, and City's playing style would have to alter considerably if the Brazil man was ever to depart.

13. Alisson – Liverpool (11)

Alisson is perhaps a better all-round goalkeeper than his Brazil team-mate, but he does not have the City star's same passing range, making him ever so slightly less valuable. In his 2022-23 form, Liverpool will not be looking for a change.

14. Darwin Nunez – Liverpool (17)

Nunez is one of the more difficult Premier League stars to gauge, missing some huge chances and sitting out matches through suspension but still netting at an impressive rate and showing signs of his enormous potential. He looks likely to be Liverpool's main man in years to come.

15. Son Heung-min – Tottenham (8)

Son has scored in only a single Premier League match this season, albeit he netted a hat-trick against Leicester City, and this first real dip in form could eventually see the forward lose his place at Tottenham given the competition for places.

16. William Saliba – Arsenal (new entry)

The first new entry is perhaps the Premier League's outstanding defender this season. Saliba has clearly benefited from three years away from Arsenal on loan, returning as a commanding centre-back, brilliant both on the ball and off it. His limited role for France at Qatar 2022 will take some explaining.

17. Martin Odegaard – Arsenal (new entry)

Another new entry and another key Arsenal man, Odegaard is Mikel Arteta's captain at Emirates Stadium and has started to show he might just fulfil the huge potential that was evident in his play as a teenager. Legendary status would be secured if he led the Gunners to the title.

18. Declan Rice – West Ham (16)

Rice has not quite been at his best for West Ham this season, but more importantly, his contract is winding down. It has been reported the Hammers have accepted their most prized asset will likely leave at the end of the season. Still, the fee should be huge.

19. Sven Botman – Newcastle United (new entry)

Botman, signed from Lille at the start of July, was not even in the Newcastle team when the season began. He is now a guaranteed starter in a side chasing Champions League football and perhaps more. Newcastle have no need to sell a centre-back who is yet to lose a match in black and white.

20. Mason Mount – Chelsea (13)

Committed to repeating the success of the Roman Abramovich era, Chelsea have no need to sell academy product Mount. But he still has not quite yet shown himself to be one of the Premier League's elite talents, netting only twice for a team down in eighth.

Fabinho believes Liverpool are well-placed to benefit from the World Cup break as Jurgen Klopp's team look to chase down their Premier League rivals.

Having fallen narrowly short of winning a second title of the Premier League era when amassing 92 points last season, Liverpool now sit sixth in the top flight, seven points adrift of a top-four place.

Jurgen Klopp's side did improve before the Premier League paused in November, and they could win three consecutive games for the first time this season when they visit Aston Villa on Boxing Day.

With France's Ibrahima Konate the only Liverpool player to remain involved beyond the quarter-finals at the World Cup, Fabinho believes the break has benefited the Reds.

"It can be good," he told the club's website. "I hope this will be good for the team because, as I said before, our position in the Premier League is not the position that we wanted it to be. 

"But this is the reality. We have to face it, we have to try to close the gap to the other teams and yes, game by game, try to play better and win."

Fabinho played 45 minutes as the Reds returned to competitive action with a 3-2 EFL Cup defeat to Manchester City on Thursday, and he was pleased to resume with a game of that magnitude. 

"In the game against City it was [important] to show that we are there, that we will fight with the best teams because we are one of the best teams as well," Fabinho said.

"I hope that we will keep this level because we will need it. To have this as the first game back from the World Cup, I think, was good for us. The intensity of the game was really good."

Jose Mourinho is a man in demand at international level, with Brazil reportedly rivalling Portugal in pursuit of his signature.

The 59-year-old is currently employed by Serie A club Roma, having joined in 2021 on a three-year contract.

There are reports that Mourinho is not entirely happy in the Italian capital, specifically regarding player attitudes and the club's financial limitations.

TOP STORY – BRAZIL TO MAKE SHOCK MOVE FOR MOURINHO

Brazil will make a sensational swoop to make Jose Mourinho their new national team boss to replace the departed Tite, according to la Repubblica.

An intermediary of Brazil's national setup will fly into Italy to meet up with the Roma head coach – who has also been linked to the Portugal job – and begin negotiations face to face.

Brazil had been linked with Manchester City boss Pep Guardiola, having reportedly turned to super agent Jorge Mendes to aid their pursuit of a new head coach.

ROUND-UP

– Journalist Bruno Andrade claims Manchester United have "overtaken" Liverpool in the race to sign World Cup winner Enzo Fernandez from Benfica. United boss Erik ten Hag is willing the trigger his €120m release clause.

– Manchester United have commenced talks with PSV winger Cody Gakpo, reports The Daily Mirror. Gakpo netted three goals in three World Cup group games.

– Fabrizio Romano claims that Barcelona have no intention of selling midfielder Franck Kessie or full-back Hector Bellerin in January.

– Paris Saint-Germain are interested in Real Madrid winger Marco Asensio, reports SPORT. Arsenal have also been linked with the 26-year-old, while Ara claims Barcelona are monitoring the situation and may swoop.

– PSG are also interested in signing Manchester United's Brazilian midfielder Fred, claims The Sun. That is despite United recently triggering a 12-month extension on Fred's contract.

– Bayern Munich have added Leeds United's French goalkeeper Ilhan Meslier to their transfer targets, reports MediaFootMercato. Bayern are looking for cover the injured keeper Manuel Neuer.

Kalvin Phillips returned from World Cup duty with England "overweight" and not ready to feature against Liverpool, according to Manchester City manager Pep Guardiola.

The midfielder has endured a frustrating season hampered by injury issues after moving to the Etihad Stadium from boyhood club Leeds United in the last transfer window.

Phillips was still selected by Gareth Southgate for Qatar 2022 but played just 40 minutes across the tournament before England suffered quarter-final heartbreak against France.

The 27-year-old, who has been restricted to just one substitute appearance in the Premier League for City, missed the EFL Cup fourth-round win over Liverpool on Thursday.

While England team-mates Jack Grealish, John Stones and Phil Foden all featured in the first game after the World Cup, Guardiola suggested Phillips' fitness was far below the standards expected.

"He's not injured. He arrived overweight. I don't know [why]," Guardiola said when asked about Phillips' omission.

"He didn't arrive in the condition to do training sessions and to play."

Guardiola is not giving up on Phillips yet, though, adding: "When he will be ready, he will play, because we need him, we need him a lot."

As for Guardiola's disappointment with him, he said: "It's a private conversation with Kalvin."

Guardiola confirmed Ruben Dias joined Phillips on the sidelines after sustaining a hamstring injury in Portugal's World Cup quarter-final defeat to Morocco.

City visit Phillips' former side Leeds on Wednesday as Guardiola's men aim to cut Arsenal's five-point lead at the top of the table.

Jurgen Klopp is adamant he can offer no insight into how much money Liverpool need to spend following claims the Reds boss will have told the club £250million of investment is required.

Former Liverpool defender Carragher made those comments while working as part of Sky Sports' punditry team for their EFL Cup last-16 defeat to Manchester City.

His words came after Liverpool's owners Fenway Sports Group (FSG) put the club up for sale last month, with FSG saying it is also open to bringing in a strategic partner.

Liverpool resume the Premier League season against Aston Villa on December 26 following the World Cup break sitting 15 points behind leaders Arsenal and seven behind fourth-placed Tottenham.

The Gunners' renaissance and Newcastle United's emergence as Champions League contenders have complicated Liverpool's pursuit of a place in the top four and leave the Reds likely facing more competition for those positions in the coming years.

"I think there's no doubt that Jurgen Klopp has said to Liverpool's owners, 'I need £250m to spend in the summer'," Carragher said, "and that sounds like an outrageous figure, but that's what Man United and Chelsea spent last summer. 

"These are the figures that the teams Liverpool are competing with are spending, and I think only once in Jurgen Klopp's tenure Liverpool have really gone for it in the transfer market, just after the Champions League final [in 2018]. They bought a lot of players, and I think it needs that now. 

"You're talking about that kind of investment, and I don't think FSG have those funds right now, that's why they're looking for investment to come in and help them."

Liverpool have been linked with Borussia Dortmund's Jude Bellingham and Benfica's Enzo Fernandez, both of whom impressed at the World Cup for England and Argentina respectively.

"Ooooh, it's Christmas time, huh?" Klopp replied when asked about Carragher's remarks.

"I don't know about what amount of money you need exactly, but I am not against investment, to be honest. 

"We will see what the future brings. Nobody knows in the moment, but I'm convinced it will be good and the future is bright for us. At the moment, we have to sort the present, and that is what we are working on."

On Liverpool's prospects in the January transfer window, Klopp replied: "I am the wrong person to ask; I don't know. January in our situation is a window where we are always prepared, that's how it is. 

"It's clear what ideas we have and how the necessity is from our point of view. All the rest doesn't lie 100 per cent in our hands. We always work with what we have got, and that will not change."

James Milner and Roberto Firmino are set to be absent as an excited Liverpool launch their Premier League "chase", manager Jurgen Klopp announced.

Milner was forced off in the 38th minute of Liverpool's 3-2 EFL Cup defeat to Manchester City at the Etihad Stadium on Thursday after sustaining a hamstring injury against his old club.

He will now be unavailable for the Premier League trip to another of his former teams, Aston Villa, on December 26, and the December 30 clash at Anfield with Leicester City.

Firmino missed the loss to City with a calf injury sustained in training, while Alex Oxlade-Chamberlain has been dealing with a virus that kept Trent Alexander-Arnold out of the last-16 defeat. Oxlade-Chamberlain came on as a substitute against City.

"Milly [Milner] will be out for a couple of games," Klopp said ahead of Liverpool's trip to Villa Park. "Same for Bobby [Firmino], even though Bobby is already on the better side of it, it's not a major thing and we will go day by day with him.

"Ox is fine. No other stuff. We have to be careful [with the viruses going around] like everyone else. Trent hopefully will be better. He hasn't taken part in a full session, let's see how that develops until tomorrow."

Liverpool resume the Premier League season following the World Cup break sitting 15 points behind leaders Arsenal and seven behind fourth-placed Tottenham.

The Gunners' renaissance and Newcastle United's emergence as Champions League contenders are complicating Liverpool's pursuit of a place in the top four, but Klopp remains positive.

"We are really excited [about the Premier League season restarting]. All the players who are back from the World Cup look really on it," Klopp said.

"Hendo [Jordan Henderson], for example, had a good World Cup and that was helpful.

"We have left a gap between us and much more exciting positions in the table. We have to chase.

"There is a lot to come, we don't think about the break any more. It's a start for something new and building on the things we've done so far and knowing and expecting that we can do better – starting on Boxing Day."

Benfica will reportedly hold out for Enzo Fernandez's full €120million release clause just six months after signing him for €10million from River Plate.

Fernandez, 21, has become one of the hottest names in football since arriving at Benfica, helping his side to an undefeated group stage in the Champions League before earning his place in Argentina's World Cup squad.

After starting the group stage on the bench, Fernandez worked his way into the starting XI for the final group match against Poland, before playing every minute of Argentina's run through the knockout stages.

His rapid rise saw Fernandez become a target of both Real Madrid and Liverpool, and despite earlier reports that he would be available for €100m, the Portuguese club will now seemingly not settle for anything less than his release clause.

TOP STORY – LIVERPOOL, MADRID TOLD TO MEET €120M RELEASE CLAUSE FOR FERNANDEZ

Portuguese publication Record is reporting the €100million bid Benfica rejected came from Liverpool, with an earlier Daily Mirror story claiming the Reds had reached a pre-agreement with Fernandez on personal terms.

Liverpool have made no secret of their desire for a new midfielder, but it remains to be seen if the extra €20million to meet the release clause will be a deal-breaker.

Meanwhile, Madrid appear to be looking elsewhere, with a fresh report from AS stating they are in the driver's seat in the chase for Borussia Dortmund's Jude Bellingham, and that they view 24-year-old Juventus midfielder Manuel Locatelli as a reliable back-up plan if they land neither Fernandez or Bellingham.

ROUND-UP

– Chelsea have agreed to a £10.5million signing of 20-year-old forward David Datro Fofana from Norwegian club Molde, per Fabrizio Romano.

– According to Repubblica, Arsenal are interested in signing 27-year-old Juventus midfielder Adrien Rabiot on a free transfer at the end of the season.

– The Evening Standard is reporting Fulham, Villarreal and Bayer Leverkusen are considering January moves for Arsenal full-back Cedric Soares.

– The Evening Standard is also reporting Crystal Palace would like to bring right-back Aaron Wan-Bissaka back to the club, three years after selling him to Manchester United.

– According to Sport, Barcelona will look to move on from Raphinha at the end of the season if he does not make himself a key part of Xavi's plans.

Kevin De Bruyne showed he is "unstoppable" when playing with "this fire inside" in Manchester City's 3-2 EFL Cup win over Liverpool, Pep Guardiola said.

De Bruyne was well below his brilliant best as Belgium were eliminated from the World Cup in the group stage earlier this month.

But his first match back in City colours on Thursday provided a reminder of the midfielder's remarkable talents.

De Bruyne supplied assists for Erling Haaland and Nathan Ake in a gripping cup tie, creating a game-high five chances in all as he ran the show at the Etihad Stadium.

As well as excelling with the ball, De Bruyne led the City press out of possession, winning four turnovers in the final third. Rico Lewis (two) was the only other player on the pitch to manage more than one.

"Kevin, when he plays with this fire inside of him, he finds himself this fire... what a player," manager Guardiola told Sky Sports.

"How many years is Kevin here? Seven, eight years? I think so. There's so many things. He's an absolute legend.

"Always I push him to find this fire. In important games, when he has this, he's unstoppable."

Guardiola reserved additional praise for Lewis, the 18-year-old right-back who took 89 touches and won five duels against the Reds – trailing only Rodri among City players in both metrics.

"In a long, long time, I didn't see a performance like Rico Lewis," Guardiola said of a teenager who debuted in August. 

"He's 18 years old, playing against Liverpool with big stars up front, and the way he played with the ball and without the ball...

"We are lucky, incredibly lucky to have this player for the next decade. Hopefully the club can keep him, because he was exceptional. The game he played was exceptional."

Jurgen Klopp was left to rue an opening 15 minutes that "killed our confidence" and conceding "completely unnecessary goals" after Manchester City knocked Liverpool out of the EFL Cup.

City beat the holders 3-2 in a thrilling tie at the Etihad Stadium on Thursday to secure their place in the quarter-finals.

Erling Haaland put the Premier League champions in front by volleying in Kevin De Bruyne's pinpoint cross, but Fabio Carvalho equalised against the run of play 20 minutes into both sides' first game after the World Cup break.

A sublime touch and finish from Riyad Mahrez restored City's lead right at the start of the second half, only for Mohamed Salah brought the Reds level again just 80 seconds later.

City were the better side, though, and Nathan Ake headed in a terrific cross from the outstanding De Bruyne to win it just before the hour-mark.

Liverpool manager Klopp told Sky Sports: "We played a formation that we haven't played for a long time, and we had to change in pretty much our last [training] session. You could see that, we needed time to adapt.

"In the first 15 minutes we had real problems and that killed our confidence and conviction a little bit."

Klopp was frustrated that De Bruyne was allowed too much time to whip in the cross for Haaland to open the scoring and switched off again to give the Belgium playmaker the chance to set up Ake following a short corner.

He added: "The goals we conceded were completely unnecessary. We had to be more switched on, especially for the third goal. Also the first goal, we should deny the cross.

"There are a lot of things we can build on and that's what we will do. It's a result we have to live with now."

James Milner was withdrawn in the first half due to a hamstring injury, but Klopp revealed he is hopeful he has not done any significant damage.

Trent Alexander-Arnold played no part due to a virus, while Virgil van Dijk is set to return to the squad for the Boxing Day fixture at Aston Villa after featuring for the Netherlands in the World Cup.

Erling Haaland scored his 24th goal of the season and Kevin De Bruyne delivered a masterclass as Manchester City beat holders Liverpool 3-2 to reach the EFL Cup quarter-finals.

The two heavyweights served up a thriller at the Etihad Stadium in their first game after the World Cup break, and it was the Premier League champions who deservedly came out on top.

Haaland opened the scoring, only for Fabio Carvalho to equalise in the first half of a pulsating tie on Thursday.

Riyad Mahrez restored City's lead right at the start of the season half, but Mohamed Salah soon levelled with his 15th goal of the campaign.

The outstanding De Bruyne then provided a second assist of the game for Nathan Ake, and Jurgen Klopp's men were unable to respond for a third time, suffering a first defeat to City in six matches.

Liverpool had been unable to cope with City's early intensity, and Haaland netted the opener 10 minutes in, getting in front of Joe Gomez to volley De Bruyne's pinpoint cross into the bottom-left corner.

The Reds were level from out of the blue 10 minutes later, Carvalho calmly stroking into the far corner after James Milner picked him out in the penalty area.

Caoimhin Kelleher denied Ilkay Gundogan and Ake after they were brilliantly set up by De Bruyne, before Darwin Nunez twice drilled wide.

Mahrez caught Liverpool out with a great touch from Rodri's pass before firing home just over a minute into the second half, yet City's lead only lasted 79 seconds as Nunez showed great pace to get away down the left and unselfishly laid an equaliser on a plate for Salah.

Liverpool were punished for another defensive lapse just before the hour-mark, though, switching off from a short corner and allowing De Bruyne to whip in an exquisite delivery for Ake to nod in.

Nunez spurned another great chance when he shot wide of the far post after bursting clear, with City this time holding on to advance.

Liverpool are ready for a "new start" ahead of their return to action in the EFL Cup against Manchester City, assistant manager Pep Lijnders has said.

Jurgen Klopp's side endured a poor showing in the early months of the season, heading into the World Cup break sixth in the Premier League standings – seven points behind fourth place and 15 adrift of leaders Arsenal.

That left Liverpool among those needing a significant improvement heading into the remainder of the season, though Lijnders believes positive signs were shown ahead of the tournament in Qatar, with results including back-to-back wins against Tottenham and Southampton.

"We see it as a new start. The boys are hungry, they are passionate, they want to show this on the pitch," Lijnders said.

"We know we have to be committed. Against City there will be moments where it will not be easy, but all our boys have this experience. It will be a top show for sure.

"I think we were on our way back, to be honest, I felt that we got momentum, and then it was the World Cup. You have to take life as it is, a lot of things you cannot change, you have to make the best out of it.

"That's what we always tried to do, we used this time to not only train the lungs, the legs, the heart, but to train the eyes and the mind with video meetings.

"We know we can be successful, there are many things left to play for."

Liverpool and other sides competing in Europe have previously shuffled their deck for EFL Cup encounters, using them as an opportunity to hand experience to younger players within the squad, and Lijnders says the World Cup showed why rotation is key.

"If there's one thing this World Cup proves, it is that you need your whole squad. The teams that became successful needed their whole squad," he said.

"When we play League Cup it's always in a busy schedule, and we know we have to be top to win these games. We cannot rest players. The boys have to be on top in games, and it's a perfect time to use the squad.

"Age is just a number, we still believe we need to give our talents chances, not just younger players against lower-league oppositions but against Premier League sides too.

"We want them to have challenges and make them struggle because that's how they improve. It's my job and Klopp's job to improve our players and to improve the team, and that's what we try to do."

Pep Guardiola insisted a desire to win the Champions League was not his only motivation for signing a new Manchester City contract, but he accepts the job would feel incomplete without a European triumph.

Guardiola secured an extension at City last month, keeping him at the club until the end of the 2024-25 season.

City have enjoyed vast domestic success under the former Bayern Munich and Barcelona coach, winning the Premier League four times out of the past five seasons.

However, a Champions League win has eluded them. They lost to Chelsea in the 2021 final and succumbed to Real Madrid in last season's semi-finals.

Guardiola knows it will be a blemish on his record if City cannot end their bad luck in the competition before he leaves.

"I admit it's the trophy that we want and of course it would not be complete – my period here – if we don't win it," Guardiola told reporters ahead of City's EFL Cup clash with Liverpool.

"But it's not the only reason I extended the contract, absolutely not. What does it mean if for the last 11 months we didn't play in the Champions League?

"Of course, I will do everything in this time we are together, we are going to try, as we tried before. Of course it's the trophy we don't have and we will try to do it."

City's trophy count under Guardiola stands at 11, but the 51-year-old is immensely grateful for the faith shown in him by the club's leadership.

"I said many times what I had here. Thank you so much for the confidence they have in me," he said. "It would be difficult to repay what in these many years, the board, all the people have shown me.

"It's difficult for me to reject them because of how they still want me and my staff, to try and do our best.

"I don't have enough words to express the incredible gratitude for this club."

After taking on Liverpool on Thursday, City restart their Premier League campaign against Leeds United on December 28. 

Pep Guardiola believes Lionel Messi is undoubtedly the greatest player of all time, describing arguments in favour of Pele or Diego Maradona as "sentimental".

Messi has long been considered among the best ever, but both he and Cristiano Ronaldo trailed Pele and Maradona in the eyes of some while neither had won the World Cup.

That changed on Sunday, when Messi led Argentina to glory at Qatar 2022, matching Maradona's achievement from 1986.

However, in the eyes of Manchester City manager Guardiola, who coached Messi at Barcelona, there was never any doubt.

"Everyone has their opinion, but nobody can doubt he's there with the greatest of all time," Guardiola said. "For me, I've said many times: he's the best.

"It's difficult to understand how a player can complete what he's done in the past 50 or 70 years.

"The people who saw Pele or [Alfredo] Di Stefano or Maradona, the people can say 'my favourite', but these opinions are sentimental.

"On the other side, if he wouldn't have won the World Cup, the opinion about what he has done for the whole of football and my opinion of how he is as a player wouldn't change absolutely anything.

"But it's normal that it depends if you win [how] you are evaluated. Of course, for him, it's the final cherries on his incredible career."

Messi was joined in the Argentina side by City striker Julian Alvarez and Nicolas Otamendi, who spent five years at the Etihad Stadium between 2015 and 2020.

"We are incredibly happy for him [Alvarez] – congratulations," Guardiola added. "For him, for Nico Otamendi, personally for Messi, for Argentina the country, for a well-deserved champion.

"For Julian, he is with us, and we are delighted. He played a lot, and his contribution was amazing to the team for the way we played. We have a world champion in our team."

Guardiola confirmed Alvarez would now enjoy "a break", but City's other World Cup stars have started to return ahead of Thursday's EFL Cup fourth-round tie against holders Liverpool.

"The players that were at the World Cup are in a better condition than the players who were here, that's for sure," Guardiola explained.

"Sergio [Gomez], Erling [Haaland], Riyad [Mahrez], Cole [Palmer]... the rhythm they miss a little bit compared, for example, to Manu Akanji and Rodri and Aymeric [Laporte] and Nathan [Ake].

"They came back and we saw them so good, perfectly. That's normal. They compete, they train every day, while we had holidays."

Liverpool and Manchester City have sent a joint statement to fans of both clubs in an attempt to ease tensions.

The chief executives of the Premier League pair wrote a collaborative email to fans ahead of their EFL Cup fourth round tie at the Etihad Stadium on Thursday.

Liverpool and City's rivalry has developed in recent seasons as both teams have competed for league titles and various cups.

The Premier League clash at Anfield in October saw coins thrown at City boss Pep Guardiola by home fans, while City supporters could be heard singing songs related to the Hillsborough disaster in which 97 Liverpool fans were unlawfully killed in 1989.

A meeting was held last month between officials and fan representatives of the clubs in an attempt to mend fences.

As a follow-up, a statement issued to fans on Tuesday by City CEO Ferran Soriano and his Liverpool counterpart Billy Hogan said: "We write to you today on behalf of both Manchester City FC and Liverpool FC, ahead of our Carabao Cup match at the Etihad Stadium later this week.

"As with any meeting between our clubs, it promises to be a fantastic spectacle of football and we are sure that you are all counting down to kick-off with much anticipation following the break in domestic football for the World Cup.

"The passion and enthusiasm that we see from our fans when we play each other – at the Etihad Stadium or Anfield – is part of what makes matches between our clubs so special, and we know you are committed to creating a stadium environment where everyone is welcomed, accepted and has a fantastic matchday experience.

"Regrettably, based on recent meetings between our clubs, we also know that a minority of fans are responsible for behaviours and actions that have no place in our game.

"We are therefore writing to ask for your full support in tackling these behaviours and to ensure that both of our clubs' good names are preserved. You can help us by reporting any incidents via the options at the bottom of this email so they can be investigated.

"We appreciate that some fans may not be aware of the impact of their behaviours on other fans, both inside and outside the stadium, and we will continue to work with our fans on this education.

"It is however important for everyone to be aware that we are fully committed to dealing with unacceptable behaviours and will take action by issuing bans to those found to be responsible.

"We have engaged the chairs from both our respective fan groups in our discussions and have their full backing to help create the right environment for our matches.

Chelsea, Real Madrid and Manchester City are reportedly the three leading candidates to land prized RB Leipzig centre-back Josko Gvardiol after his excellent World Cup for Croatia.

Gvardiol, 20, has emerged as one of the top young centre-backs in the world after breaking into Leipzig's starting XI last season, and with 19 senior caps for Croatia under his belt already, he is well established on the international stage.

Having been signed from Dinamo Zagreb for €16million in 2020, that deal has proven to be a bargain, but it remains to be seen if Leipzig feel it is good business to part ways with their young star with four more years remaining on his contract.

Gvardiol may feel his future does not lie in Leipzig, but with his contract tying him to the club until 2027, he has no leverage in negotiations.

According to The Mirror, Chelsea have been planning a raid on Leipzig for months and would like to bring Gvardiol across with Christopher Nkunku, who they are said to have already secured in a future deal.

That report states Madrid are hoping to place a bid at the end of the season, but Chelsea have a January move in mind, although with Leipzig only six points off the Bundesliga summit they will likely need a stunning offer to force their hand mid-season.

That offer could come from City, who The Sun believes are preparing a €110m bid that would make Gvardiol the most expensive defender in history.
