Ole Gunnar Solskjaer has underlined his desire to keep Donny van de Beek at Manchester United despite a difficult start to his Old Trafford career.

Since arriving from Ajax in a reported £40million deal in pre-season, the Dutchman has made just eight starts in total, with only two of those coming in the Premier League.

That lack of action prompted Van de Beek's boss at international level, Frank de Boer, to suggest this week that the midfielder might need to move on in January in order to strengthen his chances of featuring in the Netherlands' European Championship squad.

However, Solskjaer has reiterated his faith in the 23-year-old and revealed he will be handed a rare opportunity to start when United face Watford in the FA Cup on Saturday.

"I've answered this question so many times," the Norwegian said.

"There are so many examples of players needing a little bit of time – quality players. We have many players ourselves and there are other clubs with examples. Sometimes it takes time. You don't expect people who care for him to be quiet at times, especially when they want the best for them.

"Donny is going to play tomorrow. There's another chance for him. Yes, I've spoken to him and reiterated and made him aware how much we rate him. But he'll play tomorrow, and that's a good chance to kick on."

One player who could be set for a January departure from Old Trafford is Timothy Fosu-Mensah.

The 23-year-old, who is out of contract at the end of the season, has made just three appearances this term, including one start.

And Solskjaer is open to the idea of allowing him to move on should the right offer arrive.

"I'm not sure if Tim is going to stay or [if] he's going to take an option now," he said.

"He's not played enough, so of course he's been allowed to speak to clubs, with a view to leaving now in January. It's difficult when you've got good players, talented players, and you can't give them game time.

"He's now at the stage where he needs to go and play again.

"It might be [at the] end of January, or it might be in the summer that he finds somewhere else. So, he's working hard, Tim, he's ready for a move for any club that he feels ready for."

Jurgen Klopp lavished praise on Aston Villa's young players after they made Liverpool battle for their place in the FA Cup fourth round on Friday.

As a result of a training ground Covid-19 outbreak on Thursday, the hosts were forced to send Under-23s boss Mark Delaney and a team comprised of youngsters to face the Premier League champions at Villa Park.

They more than held their own for large parts, and even got to the half-time break level thanks to a well-taken Louie Barry goal.

Liverpool took the game away from Villa in the second period, ultimately running out comfortable 4-1 winners, but Klopp was impressed with what he saw from the opposition.

The German also took pleasure in the fact his far more experienced side eventually solved the 'football problems' in front of them.

He said: "The boys did really well, the kids of Aston Villa did really well, were organised and all that stuff. 

"It was clear. We scored an early goal, a nice one, and then we didn't play quick enough anymore, didn't move fast enough, didn't play the right spaces.

"These are football problems and we solved the football problems with football in the second half. So, I'm really fine with it. 

"It was a tricky one. I've never before had this kind of challenge in my life, that you have no idea who you're playing against – absolutely no idea; that you prepare a meeting and then you can throw all the preparation, all the videos in the bin and then you have to start new. 

"That's football and academy players are good players. Last year we played here with our kids and they gave Aston Villa a proper game as well. That's just how it is. 

"These young kids can all play football and if you don't play well against them you have problems. Second half, we played exactly like we should have played from the beginning and that's why we won really, the right way."

Klopp withdrew captain Jordan Henderson at half-time in Birmingham but went on to reveal that the change was not down to a new fitness issue.

Asked about a possible injury blow, he replied: "No, no, Hendo and Thiago was clear before the game that we do it like this: 45, 45. Absolutely no problem."

The German also explained that he had no concerns about his squad being exposed to coronavirus despite the late change to Villa's proposed line-up.

He continued: "No, no reservations. We trust the authorities, we had our test results come back yesterday as well, everybody was negative. Then the FA did what they thought is right with the U23s, they got tested, we got their results this morning I think at 10 o'clock.

"We were on the car park at the airport. So, then everything is fine."

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."

Liverpool survived a major scare from Aston Villa's youngsters before claiming their place in the FA Cup fourth round with a 4-1 victory.

Forced to name a starting XI comprised entirely of players without a first-team appearance to their name as a result of a COVID-19 outbreak, the Villans produced a hugely impressive performance under the guidance of U23s boss Mark Delaney.

It was enough to see them deservedly level at the break, Louie Barry finishing off a well-worked move to cancel out Sadio Mane's early header.

But Georginio Wijnaldum's strike on the hour-mark served to break the kids' resistance and was followed by further goals from Mane and Mohamed Salah that added gloss to the scoreline.

Villa would have been anticipating a long night ahead when Mane headed home Curtis Jones' right-wing cross with just four minutes on the clock.

Only two great stops in quick succession from Akos Onodi stopped the Reds doubling their lead soon after, the young goalkeeper keeping out Fabinho's low shot before rising to save Mane's follow-up.

But, while they continued to dominate possession as the half wore on, Liverpool hardly had the Villa goal under siege, and they paid the price as the hosts made the most of their first real attack.

Callum Rowe did brilliantly to evade Jordan Henderson deep in midfield before sliding an inch-perfect pass through to Barry, who saw off the challenge of Rhys Williams and produced a composed one-on-one finish that belied his tender years.

Liverpool could not have expected to find themselves in such a battle at Villa Park but responded with renewed vigour following the restart.

The pressure finally told on the hour, Wijnaldum sidefooting home in space with tired Villa legs unable to close him down, and two further goals in the next five minutes put the game to bed.

The first came from Mane, who looped a header up and into the far corner, before Salah got in on the act with a low finish into the corner.

Jose Mourinho expects his Tottenham side to take minnows Marine from dreamland "back to reality" in a historic FA Cup third round tie on Sunday.

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 competition when they meet at Marine Travel Arena.

Marine sit sixth in 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 has vowed to show the Merseyside club respect and will take a squad that could include Gareth Bale and Erik Lamela north this weekend along with the likes of Jack Clarke and Harvey White.

The Spurs boss said in a press conference on Friday: "I don't think they want to play against Tottenham under-23s, they want to play against a Tottenham team with the players they admire, they follow.

"We are trying to know their striker, their centre-back, their tactical organisation, the exactly same way we do with other opponents. I think the same way, they feel happy to play against us.

"I feel very happy to play against them. I understand the dream. It's up to us to bring them back to reality, but I clearly understand the dream. Nobody puts a foot on a football pitch feeling they are going to lose. We are top professionals. It's up to us to make them understand that as soon as possible."

Liverpool have provided video analysis of their Premier League rivals for Marine and Mourinho, whose side will get changed in the clubhouse bar, says that is to be expected.

The Portuguese said: "Liverpool helping Marine I think is normal, they are neighbours, I am pretty sure there are emotional connections between them. if they gave analysis, access to certain kinds of footage that they would not have, I feel it absolutely normal.

"What we can expect? First of all, we need to see the pitch. It's important for the safety of the players. I believe they are trying to have the best possible pitch. Then it's a group of boys playing the game of their careers.

"What can we do except respect them and win the match? I always believe to respect these teams is to beat them, is to play with a good team with responsibility, with motivation.

"A team that goes there and wins the game. That is respect. That is the cup mentality of the big teams. If we go there and we lose, of course it would be amazing for them, but would be a lack of respect from us."

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.

Frank Lampard admits he is concerned about football in England continuing while the COVID-19 crisis escalates.

On Friday, London's mayor, Sadiq Khan, declared a "major incident" in the capital as hospitals face rising numbers of patients.

The English football authorities are carrying out regular tests on players and club staff, and the number of positive cases is rising, with 40 declared in the Premier League for last week.

Lampard said none of those were Chelsea players but confirmed "a small number of staff" with the London club had tested positive recently.

Sunday will see Chelsea welcome fourth-tier outfit Morecambe to Stamford Bridge in the FA Cup third round, with the visitors having recently had to postpone two games because of coronavirus cases in their ranks.

Chelsea head coach Lampard was asked about possible worries, and said: "Not just about playing Morecambe, but I do have concerns because of the current climate.

"We haven't had any players positive in the last couple of rounds – we have had a small number of staff.

"Of course, whilst the country is in lockdown for a reason, while football carries on for a reason, it means there's lots of mixing going on.

"We have to be ultra-careful. I'm not completely comfortable but we have to toe the line, we have to keep playing.

"The safety must come first. There are lots of moving parts and things are changing day by day, week by week."

Burnley boss Sean Dyche this week floated the idea that if footballers were vaccinated, it would lead to savings on testing and such money could be ploughed into the National Health Service.

Lampard said, as Dyche did, that footballers should not be seen to be jumping the queue ahead of those in most need.

He said: "Maybe there's a time down the line when we look at sports but I don't think it's that time right now."

Chelsea will be without the injured Reece James, Andreas Christensen and N'Golo Kante for the Morecambe game, and Lampard is considering giving a first-team chance to a number of academy players.

Lampard's team have lost 3-1 to both Arsenal and Manchester City, either side of a 1-1 draw with Aston Villa, in a Premier League slump over the past fortnight.

Previous defeats in mid-December to Everton and Wolves have also played a part in them falling away from being challengers near the top of the table to sitting in ninth place.

They face a fourth-tier side who have won six of their previous seven games, yet this is Morecambe's fourth appearance in the third round of the cup, and they have lost each of their previous games at this stage without scoring.

Chelsea's last third-round defeat in the competition came in 1997-98, when they lost to Manchester United.

Lampard said the challenge of returning his team to peak form "makes my job more exciting".

He accepts "confidence has been hit" and said: "The players need a lift. That's my job, the staff's job, and their job. I don't know any way out of a lack of confidence but to sprint yourself out of it and fight yourself out of it, because those are the rules of football."

He was reminded about Chelsea being stunned 4-2 by Bradford City in the fourth round in January 2015 and said: "Underdogs will turn up, try to win and make things difficult for you.

"Considering our current form, we have to be even more on guard and worry about ourselves, and get ourselves playing well, because if we play well and do our job right, we'll win the game I believe."

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.

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.

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."
