Jose Mourinho revealed Tottenham have managed to carefully "hide" their COVID-19 problems as he insisted Premier League chiefs must not let the season descend into chaos.

The Spurs manager is relishing the distraction of an FA Cup tie at Marine on Sunday, describing the competition as "absolutely beautiful" and promising to take a star-studded squad to face the minnows.

But Tottenham would be left in an "impossible situation", according to Mourinho, if next Wednesday's Premier League clash with Aston Villa is called off.

Villa have experienced a major outbreak of coronavirus cases and their first-team training facilities were closed ahead of Friday's cup clash with Liverpool.

Tottenham have already had a London derby with Fulham called off under similar circumstances, and fixtures are piling up.

Mourinho wants a solution to be found and appealed for "leadership" from league top brass, suggesting there should be ways found to allow games to go ahead.

"The only thing I can say is that since pre-season, we knew that eventually it would happen to us, to have difficult situations to manage and to play again with 14 players," Mourinho said.

"I think every club was mentally ready for it."

Mourinho pointed to his former club Chelsea fielding Petr Cech at under-23 level recently, with the veteran goalkeeper coming out of retirement in case he is needed in a crisis.

"Every club was mentally ready for an extreme situation of having a lot of players not available to play," said Mourinho.

"In our case, we didn't have that extreme situation yet but we had problems. We had problems that of course with the legal right that we had, we managed to hide it, to hide it in a way by not telling who was positive and who was not able to play.

"But we are also having our problems. But we always thought we would always play. I cannot say much more than that."

Tottenham, like all clubs, have not been obliged to identify players who have tested positive for COVID-19, which has allowed Mourinho to avoid cases being publicised.

Those affected must go into self-isolation, but it appears Tottenham are in a good way ahead of their trip to Marine.

Mourinho remembered facing lower-league sides during his coaching career, pointing out the day his Chelsea side lost 4-2 to Bradford City in the FA Cup fourth round, back in the 2014-15 season.

"The FA Cup is absolutely beautiful," he said. "That's why, even knowing that I would love to rest all my guys. I cannot do it. It's not about being afraid, it's about giving the guys what they deserve.

"I'm not taking everybody. But out of 20, I take 19 first-team players. so you can imagine how strong we go."

Mourinho promised he would even enter the Marine club raffle, which offers a top prize of managing the eighth-tier team in a pre-season friendly. With no gate receipts, Marine are understandably looking for other ways of monetising the glamour tie.

"I will buy a ticket. Even if I win, I cannot do it," Mourinho said. "I don’t think I will have conditions to do that, but the meaning of it yes, I will be buying it."

The Northern Premier League North West part-timers and Spurs will go down in the record books as having the biggest gap between each other in the pyramid in the history of the FA Cup when they meet at Marine Travel Arena.

Marine sit sixth in their section of the eighth tier of English football, while Tottenham are fourth in the Premier League, reached the final of the EFL Cup this week and remain in the hunt for Europa League glory.

Mourinho will demand victory, of course, and will be quietly testing his players' appetite for the romance of the game.

"This is just a match that can show me how much they love football," he added. "Nothing else."

Emile Smith Rowe has the "huge potential" to match the exploits of young England stars Phil Foden and Jadon Sancho, according to Arsenal boss Mikel Arteta.

The Gunners begin their FA Cup defence at home to Newcastle United on Saturday, buoyed by a sharp upturn in their Premier League form.

A dominant 3-1 London derby win over Chelsea on Boxing Day sparked an ongoing three-match winning run.

Smith Rowe was handed a starting berth in that game and has kept his place after impressing in the number 10 role, with the 20-year-old giving Arteta's team an overdue shot of creative intent.

In 2017, Smith Rowe was part of the England squad that won the U17 World Cup, with Foden named player of the tournament.

Sancho featured during the group stages before being called back to club action by Borussia Dortmund, and Arteta acknowledged the duo are ahead of Smith Rowe in their development.

"He has huge potential. He really wants it and he has the personality when he goes on the field to express and play the way he can play," said Arteta, who coached Foden and - more briefly - Sancho at Manchester City as part of Pep Guardiola's backroom staff.

"To do it in a consistent way is a different thing. The boys that you mentioned, they've done it. It's true that they're ahead in their development phase because they've played many more minutes and games in the last two seasons.

"But he is capable of doing that. Whether he's going to do it will depend on how he continues to develop, how he takes the chance that he has in front of him and how much we can help him to achieve that."

Underwhelming loan stints at RB Leipzig and Huddersfield Town in the past two years preceded a pre-season shoulder injury, but a player dubbed "The Croydon De Bruyne" by some Arsenal fans has shown he is ready to make up for lost time.

"A lot of things have happened to him in the past year," Arteta acknowledged. "He needs to establish himself here, he needs to be successful here, he needs to really find his role and his position in the team and in the club.

"That will help him to have clear path. We really believe in him. He needs to have no fear and go for it, because he has the quality."

That quality has certainly been to the fore this season, with Smith Rowe's four assists coming at a rate of one every 93.5 minutes across seven appearances in all competitions.

With the youngster in the side, Arsenal average 2.9 goals per game. The 4-1 Europa League triumph over Rapid Vienna – in which he scored – was one of six victories Smith Rowe has been involved in this term, amounting to a win percentage of 85.7 per cent that plummets to 40 in the 20 games he spent as a spectator.

It feels infeasible that Arteta will leave him out of such a large proportion of games again but the former Emirates Stadium skipper pointed towards the examples of Bukayo Saka and Gabriel Martinelli, who completed an exciting attacking midfield trident alongside Smith Rowe against Chelsea and Brighton and Hove Albion, when discussing how younger players must have their workloads managed.

That could mean some stints playing in different positions, as Saka has during his fledgling Arsenal career, although Arteta cannot deny the much-needed lift his breakthrough stars have given Arsenal, even as he tries to manage expectations.

"Sometimes a team is a little bit concerned and has some fear because of the results, because of the pressure," he added, before noting the impact through "enthusiasm" the younger members of his squad have had.

"I think they were really helpful because they were re-energising to the team. They pushed the team into a different direction and a different rhythm as well.

"But, of course, the young players need that solidity, experience and maturity that the older players bring. It's a good combination."

Frank Lampard vowed he will fight to make Chelsea successful and declared he would have become a pundit if he had wanted an "easier" life.

The head coach, who in his playing days became Chelsea's record goalscorer, has been unable to prevent a mid-season slump that has seen the Blues slide down the Premier League table.

Four defeats in the last six games has been the sting in the tail after a long unbeaten run, yet Lampard is confident there is enough quality in his squad to turn around their season.

"I've been playing football since I could walk, and playing professionally for 20-odd years," Lampard said.

"If I didn't want that challenge, I could have sat on the telly and done an easier job. I could have been a pundit and commented on what everyone does with hindsight whenever I want, but I don't want to do that."

Instead, he is determined to prove he is the right man for the Stamford Bridge top job, and should he sense any player does not match his ambition, Lampard will consider if they belong at the club.

"The players here I feel have a real desire to get out of this mini run of bad results. I can see that in them," said Lampard. "And if there are players who don't have those concerns to get out, I think they have decisions to make.

"If there are opportunities for players to leave, it would have to be right for them, right for the club and right for myself, then that could happen. But if not, we keep fighting and moving on."

Chelsea have a break from Premier League duties when they face Morecambe in the FA Cup third round on Sunday. They lost to Arsenal in the final of last season's competition.

Lampard is set to shuffle his squad for the game with fourth-tier Morecambe, giving fringe players and possibly some academy prospects the chance to impress.

After that it will be back to the Premier League, when he expects senior players to be straining every sinew in training to earn selection.

The likes of summer signings Kai Havertz and Timo Werner have struggled this season, but Lampard says every player should be desperate to make an impact.

Havertz has found it difficult to make the transition from the Bundesliga to the Premier League, with just one goal, two assists and a mere 23 touches in the opposition penalty area for Chelsea after 15 games in the competition, 10 of which he started.

Last season, at Bayer Leverkusen, Havertz totted up 12 goals, six assists and had 140 touches in the opposition box across 29 league starts and one substitute appearance.

Lampard was determined not to focus on individuals and appears keen to give his recent recruits time to bed in at Chelsea. His concern is a wider one and addresses every player at the club.

He said: "I don't ask for them to be jumping up and down when they go home about how great I am. What I'm asking for when you're here is, to train well, back your team-mates, have a determined attitude every day, and that's it.

"I don't expect it to be a popularity contest with myself - I don't think I ever felt that in a dressing room with any manager in the best of times or in tough times.

"The players have to keep fighting in tough times. The quality is in the group, without a doubt. There will be bumpy moments and we have to stick together."

Sergio Aguero's mood is "better than ever" as he tentatively nears the end of an injury nightmare, according to Manchester City manager Pep Guardiola.

Guardiola confirmed City's all-time top scorer will start Sunday's FA Cup third-round tie against Birmingham City at the Etihad Stadium as he looks to put the after-effects of meniscus surgery behind him.

Aguero underwent an operation in June and has been forced to manage ongoing discomfort in the joint since a hamstring injury at West Ham curtailed his initial return in October.

Despite being ravaged by a coronavirus outbreak among their squad, City head into the weekend buoyed by their two finest performances of the season - a swashbuckling 3-1 win over Chelsea preceding a 2-0 win against rivals Manchester United in the semi-finals of the EFL Cup.

Four minutes from the bench at Stamford Bridge was the sum of Aguero's action across the those games, as he was an unused substitute at Old Trafford.

Nevertheless, his goalscoring prowess has been an obvious miss across the course of the campaign. In their most recent title-winning season, City averaged 2.6 goals per game in the Premier League with Aguero in the side.

That has fallen to 1.6 in all matches this time around, with a win percentage of 53.9 per cent, set against 84.8 with Aguero in harness two seasons ago. Shots per 90 minutes are also down from 18.1 to 15.6 when the two data sets are compared.

"Just look at the numbers, the quality he has in the box, Sergio is unique," Guardiola told a pre-match news conference.

"He has a tough, tough injury. The important thing is his mood is exceptional, I would say better than ever.

"It's important that the feeling, the last two weeks, his knee's reaction was really good after training. This is the best news we can have.

"He’s going to start, the minutes his performance level or knee will dictate. What's important is good quality minutes, as much as possible, we start from the beginning and after we'll see what happens.

"It will be great to have Sergio fit. He’s so optimistic. He says 'I will score goals' and that is the most important thing."

Aguero is out of contract at the end of the season, as is fellow fans' favourite Fernandinho.

The 35-year-old Brazil international has returned to his customary central midfield position this season, having deputised at centre-back for much of last, and completed the scoring with a sweetly struck volley against United in midweek.

Following the departure of David Silva over the close season, Fernandinho has stepped up as club captain and impressed Guardiola greatly with his leadership skills.

"With the players in this part of the season, everything is open," Guardiola said, when discussing the prospect of the veteran earning a fresh deal.

"I am more than impressed with the first captain role of Fernandinho, he is leading in an exceptional way. In the good moments and the bad, bad moments.

"If everyone can take an example of what he has done so far, the team will be stronger."

Pressed for examples of how the quietly spoken star commands the dressing room, Guardiola replied: "How he talks with his mates, how he talks with my assistant coach, before the game, at half-time.

"Not just talking to players about football matters, in life, how to behave in training, every single day. He's the first who proves that he's able to do it.

"That's why he goes to Old Trafford, plays holding midfielder there. It was not easy for Bruno Fernandes to control him.

"At the beginning of the season he stepped forward and showed how to be a captain."

City will have Ederson, Ferran Torres and Tommy Doyle available for selection once more, provided they returned negative COVID-19 tests on Friday.

The trio tested positive ahead of the postponed Premier League match at Everton on December 28.

Jose Mourinho warned Tottenham would be left in an "impossible situation" if their game at Aston Villa is postponed due to a COVID-19 outbreak and called on the Premier League to show "leadership".

Villa are expected to field a young side in the FA Cup third-round tie against Liverpool on Friday, as a large number of first-team players and staff tested positive for coronavirus this week.

Spurs already had a derby at Fulham called off on December 30 after the Cottagers were hit by the virus and a scheduled trip to Villa Park next Wednesday is now in doubt.

Tottenham will also face Manchester City at a later date of April 25 due to the pandemic and given they are fighting for honours on four fronts, Mourinho suggested they would refuse to accept any more postponements.

Speaking ahead of Sunday's FA Cup tie at Marine, he said: "I believe that is a completely impossible situation for a club to have three matches postponed, especially if that club plays in Europe. If that club doesn't play in Europe, of course there are the UEFA fixtures.

"For a Europa League team to have three matches postponed is impossible. Completely impossible. That's the only thing that I can say."

Asked about the prospect of facing Fulham instead of Villa, he added: "I don't know. It's not for me to find solutions. I'm not going to lie to you, I've been doing that hypothetical exercise with my staff.

"Of course, we have no influence and we don't want to have influence. The only thing that we can say is that what we did in the beginning of the season is impossible to repeat and we refuse to repeat.

"We have to defend our players, the integrity of our competitions and we would never accept to play seven matches in three weeks like we did before. One thing is [the] beginning [of the season], another thing is mid-season.

"And also because of the difficulties and demands of the matches. One thing is to play with all the risks, the Europa League play-offs, another thing is to play Europa League knockout where all the best teams are there.

"We cannot be put in an impossible situation. To have three matches postponed... it is the moment for the Premier League to show leadership, make decisions, that of course a club like us, is trying every day to be ready to play, to follow the rules that we had in our hands.

"We cannot be punished. If we don't play against Aston Villa, we will have three matches postponed and that is impossible. Because after the season we have the Euros, and of course the matches cannot be moved."

Mourinho revealed Gareth Bale trained on Friday and could travel to eighth-tier minnows Marine, while Jack Clarke and Harvey White will be in the squad.

Ole Gunnar Solskjaer has no doubt his Manchester United side are ready to bounce back to their EFL Cup disappointment against Manchester City when they host Watford this weekend.

The Red Devils were defeated 2-0 by Pep Guardiola's side at Old Trafford and have now lost each of the four semi-finals they have contested under Solskjaer.

Saturday brings another opportunity when United face the Hornets to start their FA Cup venture this season and Solskjaer expects his team to respond to this latest setback.

"The reaction has been as expected, of course you're disappointed when you go out, we wanted to go one step further but we've shown many times this season we can bounce back after a disappointment," he told a news conference ahead of the third-round tie.

"We did it after defeat against Arsenal, did it after we lost to Tottenham, after we went out of the Champions League - the boys have reacted well.

"I don't envisage anyone with any other mindset than we have to win. We enter the competition wanting to win.

"We have a few players with a few knocks, so there'll be a few changes, but I'll still field a team I feel confident in."

Odion Ighalo was drafted in as emergency cover a year ago following an injury to Marcus Rashford but his loan stint from Shanghai Shenhua comes to an end this month.

Solskjaer expects to give the striker game time against his former club, while he also offered an update on Argentine duo Sergio Romero and Marcos Rojo – both of whom are being tipped with January exits with their contracts to expire at the end of the season.

"It's special for him [Ighalo] against Watford, he will be involved," Solskjaer added.

"He's training really well, I don't know how many goals he scored today but by miles he was our top scorer in the round robin in training. 

"He's not lost sharpness or quality, it's difficult to be out of the squad of course. He did well until the summer. This season he's not had as many opportunities but he's never let himself down as a professional or a human being. 

"In training he always works hard. He's in the squad, hopefully I don't need to put him on to need goals but hopefully he can join in."

On Romero and Rojo, he added: "Both of them have contracts until the summer, they're not gonna be extended so we're looking for them to find clubs. 

"Marcos has been given time to go home, so he's still in Argentina. Sergio he has been back home as well to see family but he's back in England now. They're professionals, working hard and ready if they're called in for us. Marcos would have to travel in and do quarantine before."

Solskjaer, who confirmed Facundo Pellistri has tested positive for coronavirus but has not been involved with the first team, was asked about the worrying rise in COVID-19 cases across the Premier League.

The Norwegian acknowledged the growing concern for society but is keen for the competition not to be halted.

"First of all, you're worried what's happening in society and in and around the country," he said. 

"I personally feel safe within our bubble, I think we've taken all the steps that we've had to follow protocols, guidelines. The club have been good and the players are following the rules as well as they can. 

"Of course what's happening at different clubs and society is frightening, we have a duty to try and stay clear, stay within bubbles.

"I hope we can continue playing, I think it's [football] had a positive impact – I feel it as well at home when you don't have a game you're looking forward to watching football on the tele. The mental wellbeing of football has been a big positive, I think."

Mikel Arteta knows how he wants to improve Arsenal's squad this month but warned the transfer market is "very complicated" in the current climate.

Julian Brandt is among the reported targets for the Gunners during the January window, although Borussia Dortmund sporting director Michael Zorc insisted there had been "no offers at all" for the midfielder.

Arsenal boss Arteta this week revealed Mesut Ozil could be on the move after DC United and Fenerbahce were linked with the out-of-favour playmaker.

The London club allowed Sead Kolasinac to return to Schalke, but there has been very little transfer activity just over a week since the window opened.

Arteta would like to do get his business done early in the window, but in a week that saw Arsenal take a short-term £120million Bank of England loan due to the impact of the coronavirus crisis, the Spaniard is being realistic with his expectations.

Asked about the prospect of making early signings, he said ahead of the FA Cup third round tie with Newcastle United on Saturday: "I don't know. At the moment the market is really complicated and the situation around every club is not easy.

"To get the negotiations going it's not easy, it makes it harder because you can't be face-to-face and you cannot travel to another country to make that happen, it has to be on the phone or Zoom.

"It can go either way. I can tell you what I would like, with the players out and in sorted, but I think it's really complicated."

Arteta says it is important to understand that players may want to move on due to the pandemic.

He added: "It's affecting everything. It's affecting things transfers financially, it's also affecting some players who are here and they are stuck here for a year and realise 'I need to go back home, I need my family to be happy, to be next to me'.

"It's a bit of a mixture, but players are experiencing different feelings that probably are new to them and that's why I keep insisting this virus is about mental health as well as how you are feeling physically. Mental health is a big, big thing that we have to pay more attention to."

One player who has arrived at Arsenal is 19-year-old defender Omar Rekik, who joins the under-23 squad from Hertha Berlin.

West Ham record signing Sebastien Haller has completed a move to Ajax for a cut-price fee of £20.3million (€22.5m).

The striker has agreed a four-and-a-half-year contract with the Eredivisie giants, having previously enjoyed a spell in the Dutch top flight with Utrecht.

West Ham spent a reported £45m to bring Haller to England in July 2019 after he starred for Eintracht Frankfurt in the Bundesliga, scoring 19 goals in all competitions in 2018-19 as part of a formidable forward partnership with Luka Jovic.

However, his time in the Premier League proved largely disappointing, the 26-year-old scoring 14 times in 50 appearances in all competitions.

The Ivory Coast international was usurped by Michail Antonio as first-choice centre-forward under David Moyes and did not start a league match this season until October 31, when Antonio was struggling with injury.

"West Ham United would like to thank Sebastien for his contribution to the club and wish him all the best for his future career," the Hammers said.

According to reports, West Ham are interested in signing Lyon striker Moussa Dembele to bolster their attack, although the former Celtic forward is said to have little interest in a move to London Stadium.

Liverpool are reportedly interested in Sergio Ramos, while Real Madrid have a successor for Zinedine Zidane lined up.

Premier League champions Liverpool are linked with centre-backs due to long-term injuries to Virgil van Dijk and Joe Gomez.

And Ramos is apparently a target.

TOP STORY – LIVERPOOL INTERESTED IN RAMOS

Liverpool are interested in Real Madrid defender Ramos, according to El Chiringuito.

The 34-year-old's future at Madrid is uncertain with his contract expiring at the end of the season.

Also at Liverpool, Fabrizio Romano reports they are yet to open talks to sign Lille defender Sven Botman.

ROUND-UP

- Zidane was under pressure at Real Madrid earlier in the season, and the LaLiga giants have his replacement in mind. AS reports Raul – who is in charge of Real Madrid Castilla – is seen as the natural heir to the Frenchman.

- Christian Eriksen is expected to leave Inter, but just where to remains to be seen. CalcioMercato reports the Serie A giants are yet to receive an offer for the midfielder, who has been linked to Paris Saint-Germain and Arsenal.

- With Diego Costa having departed, Atletico Madrid are said to be looking for another forward. The Daily Mail reports Napoli striker Arkadiusz Milik is at the top of their list, while Espanyol's Raul de Tomas and Real Betis' Loren Moron are of interest.

- Manchester City are linked to Barcelona star Lionel Messi, but they may have a younger version to target. talkSPORT reports the Premier League club are plotting a move for 17-year-old Estudiantes winger Dario Sarmiento, who has been dubbed "mini Messi".

- Sergio Romero looks set to leave Manchester United. The Manchester Evening News reports the goalkeeper has bid farewell to his team-mates ahead of an expected move to Boca Juniors.

Borussia Dortmund sporting director Michael Zorc insisted there had been "no offers at all" for reported Arsenal target Julian Brandt.

Brandt, 24, has been linked with a move to the Premier League club in January.

But Zorc said no offers had arrived for the midfielder, who is contracted at Dortmund until 2024.

"I don't want to answer any rumours that were made by the media. Now there is permanently a name [Brandt] coined that we don't even think about giving up on," he told a news conference.

"Overall, we look at many different scenarios primarily due to an economical background that is simply not the best due to the ongoing pandemic.

"But I can only repeat myself again. We have no offers at all."

Dortmund, who are fourth in the Bundesliga, visit RB Leipzig on Saturday.

Jurgen Klopp says he has no problem with Liverpool not dipping into the transfer market in January as owners Fenway Sports Group are only acting in the best interests of the club. 

The Premier League champions have been badly depleted this season, particularly in the heart of their defence with Virgil van Dijk and Joe Gomez long-term absentees and Joel Matip struggling to stay fit. 

Klopp is unlikely to add to his squad during the mid-season window, but the Reds boss understands it is difficult to do business at this time even without the financial impact of the coronavirus pandemic. 

The Liverpool boss insists he is on the same page as club ownership, no matter the key absences that could undermine their push for trophies. 

"In good times everyone thinks our owners are really generous – 'My God, big signings, whatever’ – and in bad times everyone thinks they are really tight – maybe because they are from a different country – but they are not, they are absolutely concerned about the club and success of the club," Klopp said. 

"And that is an understanding how we have it. They see exactly the same things I see about necessity of players and stuff – it's not that I say 'By the way a centre-half would be really nice’ and they say, 'Wow, a centre-half. Really? Why?' 

"It is all clear, all on the table, we work on that. It is the situation and on top of that we have January, not the easiest transfer window, having not the money exactly like we want. 

"It is a window where other clubs say, 'No, we have enough [money] to survive' so we don't do anything on our targets. 

"It is nothing to do with worrying [about whether it will impact their chances of winning trophies] or not. These are the facts.

"My job is to deal with the circumstances which I always do. If the world would be in a completely normal place, we would try everything to do the right stuff now but the world is not in a normal place so I don't know why we constantly try to treat the football like it is independent of other issues around."

Liverpool are due to be in FA Cup action on Friday, though their tie with Aston Villa is in doubt due to a coronavirus outbreak in their opponents' camp.

Villa announced on Friday they had closed their training ground as a consequence, while the Football Association will make a decision on whether the game goes ahead following further testing.

The Football Association (FA) is still hopeful Aston Villa's meeting with Liverpool can go ahead as planned on Friday, with a final decision to be made after further coronavirus testing.

Villa announced on Thursday they had closed their Bodymoor Heath training ground after "a significant coronavirus outbreak" at the club, with first-team training cancelled after players and staff returned positive results.

Their FA Cup third-round clash with Premier League leaders Liverpool was consequently thrown into doubt, though it is hoped the fixture will not have to be postponed.

An FA statement read: "The Football Association and Aston Villa are working closely together to try to ensure that the club's FA Cup third round proper fixture with Liverpool can go ahead as planned at Villa Park.

"Final confirmation will be made tomorrow pending the results of additional COVID-19 testing."

It was announced earlier on Thursday that the third-round clash between Shrewsbury Town and Southampton would not go ahead on Saturday after "several" members of the League One side returned positive coronavirus results.

Derby County this week revealed they will select a side made up of Under-18 and Under-23 players for their tie at non-league Chorley on Saturday, with interim boss Wayne Rooney and his first-team squad staying at home following a coronavirus outbreak at the Championship club.

Liverpool are set to stick with their threadbare options at centre-back rather than recruiting a January replacement for Virgil van Dijk or Joe Gomez. 

The Reds have played much of the season so far with midfielder Fabinho in defence alongside a rotating cast of partners after long-term injuries to their starting duo. 

Joel Matip has been limited to just eight Premier League appearances due to his own fitness issues and is facing a race to be back for a vital game against Manchester United next week. 

Academy graduates have stepped in, with Nathaniel Phillips playing three times and Rhys Williams twice in the league, while captain Jordan Henderson lined up at centre-back in Monday's defeat to Southampton. 

Although Henderson and Fabinho won nine of the 11 duels they contested between them in that match and still ranked second and third for total touches, it is not an ideal fix. 

And such issues have prompted reports of interest in Schalke's Ozan Kabak and Lille's Sven Botman, although The Athletic reported on Thursday that Liverpool will not pursue either option in the mid-season window. 

Jurgen Klopp said prior to the game against Southampton that the club would do "the right thing" this month - and that appears to mean opting against a new signing. 

Asked if he could rule out a transfer as he previewed the scheduled trip to Aston Villa in the FA Cup, Klopp replied: "I cannot say definitely we will not bring one in. It's just not likely because of the situation in the world. 

"We should not forget that the [coronavirus] situation is a tough one for all people and for football clubs as well.

"There might be some clubs with absolutely no financial problems, but this club always was and will always be - with these owners, for sure - very responsible with the things we do. 

"If the world would be in a normal place, everything would be fine, we won the league, won the Champions League, the club is in the best possible situation, and you have three senior centre-halves all injured, is that a situation where you would normally do something? Yes, definitely. 

"But we are not in that situation, so I don't know if something will happen or not. 

"We maybe could do something, but it would be a short-term solution and we don't have a short-term solution, so it's not right because it does not help. 

"We have to get through this. It's not the best moment for the whole planet, so why should it be for this football club?" 

While rotation has been enforced in the middle of the defence, full-backs Trent Alexander-Arnold and Andy Robertson have remained automatic picks. 

Alexander-Arnold tested positive for COVID-19 in pre-season and has also battled a calf injury, yet has still played 15 of Liverpool's 17 league matches. 

The right-back's performance level has dipped this season and his first error leading to a goal handed Southampton a 1-0 win on Monday. 

There was criticism of Alexander-Arnold after that match, in which he was substituted, and Klopp acknowledged on Thursday it was "not his best game", though backed the England international to recover. 

"The reason is he was out for a while with COVID and had an injury which didn't help," Klopp said. "He had no pre-season really. 

"Then with the quality he has and the situation we were in, he played pretty early. He's now getting there. 

"Physically he's fine, he just has to find his top shape again, and that will happen sooner rather than later."

Aston Villa closed their training ground on the eve of Friday's FA Cup third-round clash with Liverpool due to a "significant" coronavirus outbreak.

Villa on Thursday revealed a large number of first-team players and staff are isolating after testing positive for COVID-19 this week.

The first team did not train the day before they are due to face Premier League champions Liverpool at Villa Park and talks are being held over the scheduling of the tie.

"Aston Villa can confirm that the club has closed its Bodymoor Heath training ground after a significant coronavirus outbreak," a club statement said.

"A large number of first team players and staff returned positive tests after being routinely tested on Monday and immediately went into isolation.

"A second round of testing was carried out immediately and produced more positive results today.

"First team training ahead of tomorrow's FA Cup match with Liverpool was cancelled.

"Discussions are ongoing between medical representatives of the club, the Football Association and the Premier League."

Jurgen Klopp acknowledged Liverpool are enduring a tough run but insisted performances have not been as bad as results suggest.

The defending Premier League champions are top of the table again but have won just two of their past six matches – and two of seven in all competitions.

Rivals Manchester United, who have a game in hand, have moved level on points with the Reds at the summit ahead of the two sides meeting next weekend.

"We were not waiting for [this run of form] and we do not enjoy it, but it's not unlikely that these kinds of things happen," Klopp told a news conference on Thursday.

"I think we only won two of the last six – that's not the standard we expect from ourselves, obviously.

"So, we don't take it easy, but we still see what we can improve, what we have to improve, and don't think everything was bad in the last few weeks.

"The league is too strong, and if you struggle a little bit, immediately the results go the other way because the opponents are fighting with everything they had. You saw that against Southampton [a 1-0 defeat on Monday]."

Liverpool must first focus on the FA Cup, however, with Aston Villa hosting Klopp's men in the third round on Friday.

Last season's run to round five was Liverpool's best under Klopp, with the Anfield outfit eliminated from four of their past six ties against fellow Premier League sides, only beating Everton (in 2018 and 2020) in this time.

The Reds had reached the semi-final in the final season before Klopp's appointment, losing to Villa in the last four to end a six-match winning run against Friday's opponents in the competition.

Despite his underwhelming record in the competition, the manager says Liverpool have always been determined to succeed.

"It's important. It's the FA Cup," he said. "We didn't go far so far in this competition.

"I didn't think we were blessed so far with sensational draws so far and now we go to Aston Villa, which is a tough one as well.

"We always took it very seriously and will do this time as well, but we cannot forget the intensity of the period we are in and all these kinds of things.

"It's important – football games are important. We are professional football players or coaches or managers and the only thing we have to do is to win football games and to try to make sure that we really can do that. It's a very important competition, so we will try to win that."

Liverpool were beaten 7-2 by Villa in the Premier League this term, shipping seven goals in a single match in any competition for the first time since 1963.

Klopp is therefore reluctant to name a weakened team, even with the United game on the horizon.

"We need to find the balance to field a team where we didn't change too much," he said. "We bring in fresh legs again.

"The rhythm [for returning players] is a different issue. That's step by step. We cannot do that in one game. We can't use the FA Cup to give players rhythm – the opponent is just too strong for that.

"After the Aston Villa game, we have eight days between Villa and Man United, so that's a long training week where we can do a lot of stuff in 11-v-11 situations, which will help the players a lot, especially the players who were out for a while. After that, we will be in a different place."

Pressed on specific injuries, Klopp added Naby Keita would return "soon" but not this weekend and Liverpool "will try" to have Joel Matip back for Manchester United, although Diogo Jota is still wearing a brace on a damaged knee.
