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James Milner was withdrawn in the first half due to a hamstring injury, but Klopp revealed he is hopeful he has not done any significant damage.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

Manchester United will host third-tier Charlton Athletic in the quarter-finals of the EFL Cup, while Manchester City face Southampton after eliminating last season's winners Liverpool.

Goals from Christian Eriksen and Marcus Rashford saw United beat Championship leaders Burnley at Old Trafford on Wednesday, and another home tie will await the Red Devils in the last eight.

League One Charlton are the only non-Premier League side remaining in the competition after the Addicks won a penalty shoot-out to upset Brighton and Hove Albion on Wednesday.

United boss Erik ten Hag is looking to end a five-year trophy drought for the club, who have not claimed any major silverware since Jose Mourinho led them to Europa League and EFL Cup glory in 2017.

Meanwhile, United's rivals City will visit Southampton after overcoming Liverpool in a thrilling fourth-round tie on Thursday, with Erling Haaland, Riyad Mahrez and Nathan Ake scoring in a 3-2 victory.

City have won the trophy in five of the past seven seasons and will equal Liverpool as the most successful club in EFL Cup history if they win their ninth title this term.

Newcastle United will host Leicester City in another all-Premier League tie after overcoming Eddie Howe's former club Bournemouth on Tuesday, while Wolves visit fellow strugglers Nottingham Forest. 

The ties will be played in the week commencing January 9, following the third round of the FA 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.

Erik ten Hag provided a blunt reply when asked when Jadon Sancho will return for Manchester United but insisted Aaron Wan-Bissaka has a future at the club.

Sancho last featured for United on October 22 in a 1-1 draw against Chelsea and was omitted from England's World Cup squad.

The winger did not travel with the squad for a warm-weather training camp in Spain during the domestic break for Qatar 2022 either, having instead been placed on an individual programme to work on his fitness.

United were back in action on Wednesday in a 2-0 triumph over Burnley in the EFL Cup and manager Ten Hag was asked if he knew when Sancho would be available for selection by Sky Sports, to which he merely replied: "No."

Pressed on if there was a timeline for the former Borussia Dortmund star's return to action, Ten Hag gave the same reply.

However, he did provide a lengthier response to questions about Wan-Bissaka, who has struggled with injuries this season.

The full-back set up Christian Eriksen for United's first goal, before Marcus Rashford's fine individual effort sealed United's progression to the last eight.

Wan-Bissaka has struggled for consistency since arriving from Crystal Palace in 2019 and has been linked with a return to the Eagles.

Ten Hag, though, says the defender can cement a place at Old Trafford.

"Aaron Wan-Bissaka, it is clear he has a future," Ten Hag told reporters on Wednesday. "He's had some good years with United, but from the start of this season he had a lot of illnesses and injuries, and so was running behind.

"His fitness levels are getting better, his performance levels are getting better.

"When you get an assist, especially the way he got that assist with his movement and the right moment, the timing and then great pass of course from Bruno [Fernandes]. But this is great and so I'm happy with his performance. He did good."

Marcus Rashford declared "there is no time to feel sorry for yourself" after scoring on his Manchester United return after World Cup heartbreak with England.

Christian Eriksen and Rashford were on target as United breezed to a 2-0 win over Vincent Kompany's Burnley to reach the EFL Cup quarter-finals at Old Trafford on Wednesday.

Rashford scored three goals in Qatar before England were eliminated by France in the last eight after Harry Kane missed a late penalty in a 2-1 defeat.

The forward has been involved in 13 goals in 12 EFL Cup appearances, scoring nine and assisting four, and assured his focus remains on United and not on the disappointment in the Middle East.

"It is good to play again but it was a tough game and it was good to get a win to take into the next game," he told Sky Sports.

"[The World Cup loss affects you] more emotions-wise because it was such a disappointing feeling to be knocked out and you have to pick yourselves up.

"There is no time to feel sorry for yourself. You need to pick up results and thankfully we did that. It was fun to be out there."

The 25-year-old believes the EFL Cup can propel sides to success in the Premier League, with United sitting three points behind fourth-placed Tottenham – who have played a game more.

He added: "We are in every tournament to go on and try and win it. This one is a good one to win. 

"Winning this early in the season, in February, can push you on to go and achieve things for the rest of the campaign – we are going to try and do that."

United manager Erik ten Hag hailed the versatility of Rashford, who will be expected to play a vital role in the second half of the season after Cristiano Ronaldo's exit.

The Dutchman told Sky Sports: "He was a constant threat. Playing on the backline of them, he is so dangerous, with his movement with and without the ball, he creates so much and then you see the benefits."

Raphael Varane and Lisandro Martinez were both unavailable after Argentina defeated France to lift the World Cup on Sunday.

Ten Hag does not expect to have Martinez back for the time being as the celebrations in Argentina continue, while he refused to offer an update on the return of Jadon Sancho, who was not named among United's substitutes.

"In Argentina, I think they are still celebrating," he added. "We will see, the Premier League is going to restart and we have to be ready for that."

Ten Hag's side return to Premier League action at home to Nottingham Forest on Tuesday.

Christian Eriksen and Marcus Rashford were on target as Manchester United eased into the EFL Cup quarter-finals with a 2-0 win over Burnley on Vincent Kompany's return to Old Trafford.

Manchester City great Kompany enjoyed numerous derby victories over United but his Red Devils reunion as Burnley manager ended in a fourth-round defeat on Wednesday.

Eriksen opened the scoring with a 27th-minute strike before Rashford doubled the advantage in the second half of United's first game since the World Cup.

Championship leaders Burnley impressed in parts but were punished for wasteful finishing as Erik Ten Hag's side booked their place in Thursday's last-eight draw.

Alejandro Garnacho squandered a glorious eighth-minute chance as Bailey Peacock-Farrell raced out to keep out a tame finish after Bruno Fernandes' incisive pass.

Fernandes provided another defence-splitting diagonal ball for Aaron Wan-Bissaka, who acrobatically hooked across for Eriksen to tap home a deserved opener.

A curled Manuel Benson strike forced a smart save from Martin Dubravka, who almost turned into his own goal from the resulting corner, before Peacock-Farrell pushed away to deny Antony Martial at the other end.

Scott McTominay whipped a presentable opening over after the interval, but Rashford extended United's lead when his powerful run ended with a drilled finish into the bottom-left corner.

Darko Churlinov wastefully prodded wide on the counter-attack and Ashley Barnes blazed over as a profligate Burnley showing ensured there was no way back for the Clarets.

What does it mean? United back firing after World Cup

United ended the first half of the Premier League season positively to sit three points behind fourth-placed Tottenham, who have played a game more, before the World Cup break.

Ten Hag's side picked up where they left off, albeit they were unconvincing at times in the first half, as United progressed from a sixth straight EFL Cup clash against Burnley.

United had lost three of four home ties in the competition before this victory, though Ten Hag will still demand improvements with tougher tests to follow when the Premier League returns.

Fernandes shines after Ronaldo departure

Questions were often posed as to Fernandes' influence alongside Portugal team-mate Cristiano Ronaldo at United before the latter had his contract terminated in November.

Playmaker Fernandes shone in his first game without Ronaldo as he created a game-leading three chances, including a pinpoint pass for Wan Bissaka's assist in the first half.

Deputy Dubravka unconvincing

David de Gea remains Ten Hag's first-choice goalkeeper and the Spain goalkeeper may have little concern over his position after an unconvincing performance from Dubravka.

The Slovakia international almost punched into his own net before a poor touch nearly gifted Burnley an equaliser and was caught out again in stoppage time, though those errors proved to be irrelevant.

What's next?

United return to Premier League action at home to Nottingham Forest on Tuesday, when Burnley host Birmingham City in the Championship.

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."

Erik ten Hag has told his Manchester United stars to "live the high standards" it will take to carry the club back to the top of English football.

The United manager has the bulk of his squad back together after the World Cup interval and will embark on the next stage of rigging up a group capable of challenging for titles.

Former Ajax coach Ten Hag says his players must not "get too satisfied" with their progress, which he nonetheless feels has been significant since a difficult start to his reign.

United will be back in action on Wednesday when they host Burnley, leaders of the Championship, at the EFL Cup last-16 stage.

Their first Premier League game after the resumption comes on December 27 when they tackle Nottingham Forest.

Ten Hag said: "Satisfaction makes you lazy. So don't get too satisfied with yourself as a team. Give every day the best.

"Only when you set those high standards and keep the high standards – it's up to me to control that and give that example, clear. But the players and staff at Manchester United have to live the high standards, and then it's possible to compete with the best clubs in the Premier League and achieve our goals.

"Where we were at the start of the season, we were just not good enough. I knew it when I stepped in that we would have days like that, that we would have defeats."

United lost their opening two Premier League games of the campaign to Brighton and Hove Albion and Brentford, but they have recovered strongly to win eight of their next 12 in the competition to rise to fifth place, three points off the top four with a game in hand.

They were last champions of England in 2012-13 and have not won a major trophy since landing the EFL Cup and Europa League in the 2016-17 season.

Ten Hag, who spoke to the Manchester Evening News and national newspapers during a training break in Spain, said it was obvious he was taking on "a difficult project".

"Manchester United was not in the circumstances that you would expect of them, and I think now we're in the right direction, but we're far away from where we need to be," he said.

United have lost three of their last four home games in the EFL Cup, as many as they had in their previous 36 at Old Trafford, and Ten Hag will be wary of the threat Burnley pose.

The Dutchman is confident United can keep building in the coming weeks and months, but bringing everyone back into tune with how he wants to play is another challenge. Many have been away with their national teams, playing and being coached in contrasting ways to his methods.

"Players come back and they have been playing six weeks in a different environment and different style of play," said Ten Hag, "and then they have to get back to our style and system and our rules and principles, and it's a team sport. So, all 11 have to be on the same page."

The mentality of Argentina's World Cup-winning defender Lisandro Martinez can help Manchester United end their five-year trophy drought this season, according to Scott McTominay.

Martinez initially struggled after swapping Ajax for United in July, but the defender has since emerged as a key part of Erik ten Hag's new-look team, who sit fifth in the Premier League.

Martinez appeared in five of Argentina's seven games in Qatar – starting twice – as Lionel Messi led the Albiceleste to their third title, which was clinched with a penalty shoot-out win against France.

Addressing United's fans ahead of Wednesday's EFL Cup last-16 tie against Burnley, McTominay detailed his first conversation with Martinez after Argentina's triumph, saying the Red Devils must adopt a winning mentality to challenge for silverware.

"Success will always be winning trophies and that's the most important thing at this football club," McTominay said.

"With the manager that we've got now, we've got a really good opportunity to start that journey, especially this year. 

"We've got a really good chance to implement ourselves and really start pushing. I feel like this is the year where we can go for it and that’s firmly reiterated by all the coaches and in the squad.

"I messaged Lisandro the other day and said congratulations and he said, 'we go for the next one'. He's just won a World Cup, so that shows the mentality that is in the group."

Martinez is not the only Argentine to impress for United this season, with teenage winger Alejandro Garnacho scoring twice since breaking into the first-team squad.

Garnacho scored a stoppage-time winner in United's most recent Premier League game at Fulham, and McTominay believes there is no limit to the 18-year-old's potential if he remains grounded. 

"He's a hell of a footballer and if he keeps his feet on the ground and keeps learning and keeps wanting to work hard, then he can do what he wants in football," he said.

"He's such a talented player and we've got to keep him humble and keep him working hard as well."

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.

"If we all stand together to report the behaviours and actions that cause harm – including inappropriate gestures, chanting, throwing of objects, as well as any and all forms of discrimination – then we can all concentrate on supporting our teams.

"Thank you for taking the time to read this email, and for your commitment to help eliminate unacceptable behaviours in football."

Pep Guardiola made it clear he is not happy with Manchester City's schedule after the World Cup.

City defeated Girona 2-0 in a friendly on Saturday, with Kevin De Bruyne and Erling Haaland getting the goals.

The pair were two of four outfield players among City's first-team regulars, along with Riyad Mahrez and Ilkay Gundogan, to have started the match.

Reserve goalkeeper Stefan Ortega and back-up left-back Sergio Gomez also featured from the off, but the rest of the squad was made up of academy players.

City face Liverpool in the EFL Cup last 16 on Thursday, before taking on Leeds United and Everton on December 28 and 31 respectively in the Premier League, and Guardiola claimed he did not yet have enough players to prepare for the festive fixture list.

"We have four players – five players," Guardiola told City's official media channel.

"We have to see how they are coming back [from the World Cup]. We don't have players. The big brains of football made this schedule so we are going to play this game."

City had plenty of representation in Qatar, though De Bruyne and Gundogan had returned after early exits for Belgium and Germany respectively.

Aymeric Laporte and Rodri were knocked out in the last 16 with Spain and will return next week, while England internationals Kyle Walker, Phil Foden, John Stones and Kalvin Phillips, along with Portugal trio Ruben Dias, Joao Cancelo and Bernardo Silva, as well as Netherlands defender Nathan Ake, are also set to join back up with the squad soon.

"Some players coming back now, in the next few days, step by step we have the people here," Guardiola added.

"People are coming back soon. After that the English players and Portuguese – they're coming back."

Indeed, despite being one of the best teams in world football, City have only one player who will be competing in the final between Argentina and France on Sunday.

Julian Alvarez has been one of Argentina's best performers in Qatar, scoring four goals, including twice in their semi-final win over Croatia.

"All of us are really happy for him," said Guardiola.

Jurgen Klopp has suggested he will not consider selecting Virgil van Dijk for Liverpool's return to action against Manchester City next week.

Van Dijk returned to training with Liverpool in Dubai this week on the back of the Netherlands' elimination from the World Cup against Argentina last Friday.

The 31-year-old played a full part in all five of his country's matches in Qatar – including extra time in the quarter-final loss to Argentina – totalling 480 minutes of action.

However, while Klopp does not want to rush Van Dijk's comeback, he has yet to make a call on England duo Jordan Henderson and Trent Alexander-Arnold.

Henderson did not finish any of the three England matches he started, while Alexander-Arnold managed just 33 minutes on the field across the Three Lions' five matches.

"Yes, there's a chance, of course – they're training already," Klopp told Liverpool's official website when asked if any returning World Cup players would be in action against City.

"Hendo is already training here. Virgil is training here, but I don't think we will try that. Hendo we will see, Trent we will see. 

"But this group worked now together for nearly two weeks and we made a real step and that's cool. I don't know in this moment.

"I hope we all get through it and we all know in England, and in Europe in general, there's kind of a virus going around, so we hope we can stay out of that. 

"Then we'll make the decision obviously on Wednesday who can play on Thursday. But it's good and will be a very interesting game after that period, but I'm looking forward to it."

Liverpool defeated Milan 4-1 in their second mid-season friendly on Friday, with Darwin Nunez – who suffered early World Cup heartbreak with Uruguay – scoring twice.

Mohamed Salah and Thiago Alcantara were also on target for Liverpool in the United Arab Emirates, where Klopp used 22 different players, including a number of youngsters.

"In general, tonight was the result of the last 10 days what we saw in training and tonight we could bring it on the pitch, which is obviously nice," Klopp said.

"I'm not sure the academy [players] could watch the game tonight but when you see these boys and performing in a game like this, it's cool. 

"It's a real physical game, adult football is a physical game and the boys need to make these steps so they can get ready for it step by step. 

"The physical part will come but until you are that strong, you can create a lot of ideas, you can do things a bit smarter. 

"There was a lot of really good things tonight and that's why we play football. We want to see good football games."

Liverpool's trip to the Etihad Stadium is followed four days later by a visit to Aston Villa on their return to Premier League action, before hosting Leicester City on December 30.

Manchester United's EFL Cup tie with Burnley will be played in front of a reduced capacity, following advice from safety authorities.

The Red Devils welcome the Championship leaders to Old Trafford for the last-16 clash on Wednesday, with Clarets boss and ex-Manchester City captain Vincent Kompany returning to the home of his former rivals.

The match coincides with a day of industrial action affecting North West Ambulance Service, culminating in the unavailability of ambulance service personnel.

At the request of the authorities, tiers in the West Stand and North Stand are required to be closed as part of a "robust" medical plan, which will allow around 62,000 fans to be in attendance, with Old Trafford usually able to house around 74,000.

"Everyone at Manchester United shares the inevitable disappointment caused by this news, particularly to those ticket holders who will be impacted," a statement on the club's official website read.

"However, the safety of our fans is always our priority. As the match is currently sold out, we have written to fans in the affected areas offering the option of a full refund. 

"No action is required from fans with tickets in other areas of the ground at this time. We will do our utmost to relocate anyone who is impacted and has not chosen to accept a refund, prioritising full and cup season ticket holders."
