Sergio Aguero is felling better every day after returning to training but Pep Guardiola is unsure when the Manchester City striker will be available for squad selection.

City's all-time record goalscorer has endured a frustrating campaign and has not featured since coming on as a late substitute in the 3-1 win over Chelsea on January 3.

That is one of only nine appearances made all season by Aguero, who struggled with knee and hamstring issues before being struck down with coronavirus last month.

He returned to training on Monday but Guardiola cannot say for certain when the Argentina international will feature again.

"Yesterday he trained with the group for 10-15 minutes and later did some part alone," Guardiola said at a news conference ahead of Wednesday's FA Cup tie with Swansea City.

"Day by day he is feeling better. Is he ready? Not yet."

City make the trip to Wales on a 14-game winning run in all competitions, including a 4-1 victory over Liverpool on Sunday to tighten their grip on top spot in the Premier League.

That equals the all-time winning run by an English top-flight side but Guardiola has warned his players they cannot afford to take last-16 opponents Swansea for granted.

"I can't explain it. I just think about the next game and try to prepare for it as well as possible - there are no more secrets than that," the Catalan coach said.

"We are so calm when we lose and the same now we are winning. The reason why is thinking the next game and now it's Swansea."

City's winning run has come despite the absence of Aguero, with Guardiola often preferring to go without a recognised striker up top - as was the case against Liverpool.

"We play with a centre forward many games," Guardiola said. "When we don't play with a typical centre-forward people can move a bit more but we have to arrive in the box. 

"We saw the game against Liverpool - four or five players were inside the box. Every game is different. 

"We are looking forward, even Gabriel [Jesus] is dropping, improving in his position not playing like a player you can link and the striker just being there. 

"I'm not a big fan of this. I prefer to move behind this position and we have some players who can do it."

Wednesday's clash at the Liberty Stadium will be the first between Man City and Swansea since a dramatic FA Cup quarter-final in 2018-19, which the Citizens edged 3-2.

Guardiola's men have won 12 of their last 14 meetings with Swansea in all competitions, including each of the last six in a row.

However, the Welsh side have been in good form of their own of late, winning eight and drawing two of their last 10 matches, and are seeking to reach the last eight for a third time in four seasons.

Guardiola saw his side survive a scare against fourth-tier Cheltenham Town in the last round and is expecting another tough test against Championship promotion contenders Swansea.

"Swansea have a tradition of good managers: Michael Laudrup, Roberto Martinez, [Graham] Potter - now I realise how good he is as we suffered a lot when we played Brighton," Guardiola said.

"It was a difficult game the last time we played Swansea. I don't expect a different game to when we suffered there two seasons ago to go through. 

"I know they are consistent, score, good defensively, don't concede chances, so solid in their formation, physically strong, they have the quality to play upfront and in the middle. 

"It will be an incredibly difficult test. We have to do a good performance. We suffered against Cheltenham, 1-0 down with 80 minutes. I don't expect a different game tomorrow."

Man City have won 18 of their 21 FA Cup ties under Guardiola and have scored more goals (65) in the competition since the Catalan arrived in 2016-17 than any other side.

Paul Pogba will miss "a few weeks" for Manchester United, Ole Gunnar Solskjaer has confirmed in concerning news ahead of a key month.

World Cup-winning midfielder Pogba returned to United's starting line-up to face Everton at the weekend but lasted just 39 minutes of the 3-3 draw.

The 27-year-old appeared to suffer a thigh injury and was quickly deemed a doubt for Tuesday's FA Cup fifth-round clash with West Ham on Tuesday.

Solskjaer has since revealed the extent of the issue, which could keen Pogba out of a series of big matches.

United play Real Sociedad home and away in the Europa League in February, before visiting Chelsea in the Premier League at the end of the month and Manchester City on March 6.

"It's an injury that will take a few weeks to heal," Solskjaer told MUTV. "He's just started his recovery, working with the medical staff and we'll get him back as soon and safely as we can.

"Of course, Paul has been very important for us and we're not going to take any risks. [It will be] a few weeks, definitely.

"You never want to be injured and, especially, now Paul was really finding his form and enjoying his football. For us, we just have to take as many points and wins as possible, when you lose players.

"We've been very healthy and strong for a long period so we can't moan too much."

Pogba scored winning goals at Burnley and Fulham in January, although United's form has since suffered a little, allowing City to build a five-point gap at the summit with a game in hand.

Meanwhile, Solskjaer suggested that captain Harry Maguire could be given a rest against West Ham, having sat out just two games since the campaign started.

"Of course I think about if he needs a rest, if he physically can keep going and going," said the United boss.

"The nature of a centre-back position is a different position compared to full-backs and wide men or even central midfielders, or any other position on the pitch. The centre-backs are the ones who are protected mostly from the real fatigue because you're working less.

"Then again, he's never injured, Harry. He's never been really badly hurt, touch wood, and hopefully he'll be able to carry on. But I'm not sure if he'll play on Tuesday or not. I've not decided yet."

United have scored 12 goals across their past two games and although Mason Greenwood did not find the net in the 9-0 win over Southampton or the draw with Everton, Solskjaer has been impressed by his recent displays.

Greenwood created two chances – one of which ended in an assist – and had two efforts on target against Southampton, while he also completed three dribbles. Versus Everton he failed to hit the target or supply a key pass, but was again successful with three of his five attempted dribbles.

"Mason was different class [against Everton]. I thought he was the standout performer on the pitch - he just didn't get the goal that his performance deserved," said Solskjaer.

"I think the last few games, if you look at him closely - yeah, I know we scored nine against Southampton - but if you look at his performance, I thought his performance was top.

"He's improved and matured immensely, and he's working with some of the top forwards in the country, of course. He's learning off them, and it's exciting to see that he's come over his blip and is playing really well."

Concussion substitutes will be trialled in the Premier League from February 6, English football's top division has confirmed.

A maximum of two substitutes will be allowed in addition to the stipulated allocation of three substitutions in the event of a player suffering a head injury and showing symptoms of concussion.

The Football Association (FA) and the Premier League applied to the International Football Association Board (IFAB) to introduce the trials .

The 12:30 GMT kick-off between Aston Villa and Arsenal on February 6 will be the first game of the trial, which runs until the end of 2020-21, with an option to extend into next season.

The Women's Super League and Women's Championship will also take on concussion subs from the same date, with the men's FA Cup introducing them from the fifth round on February 9-11.

Concussion substitutes in the FA Cup would be in addition to the five clubs are permitted to make in this season's competition.

A Premier League statement read: "The trial is a result of the IFAB's consultation with stakeholders and recommendations from their concussion expert group to allow additional substitutions for players with actual or suspected concussion."

FIFA has also moved to use concussion substitutes at the forthcoming Club World Cup, although teams at next month's tournament will only be able to make one such replacement per match.

Arsenal captain Pierre-Emerick Aubameyang thanked fans for their support after explaining he had missed recent matches after his mother took ill.

The forward sat out consecutive trips to Southampton - a 1-0 FA Cup defeat and a 3-1 Premier League win - with what the club described as "personal issues".

Manager Mikel Arteta had admitted he was unsure when the Gabon international would be able to return, with the Gunners now preparing for league games against Manchester United and Wolves over the next six days.

Aubameyang suggested he could be back soon as he confirmed his mother was recovering.

"Thank you so much for all the messages and calls over the last few days," he wrote on social media on Wednesday.

"My mother is going through some health issues and I had to be there for her. She's already much better now and I will be back home tonight. I'm more than grateful to the doctors and nurses helping her get through this.

"And of course, thanks to my Arsenal fam for the love yesterday! I'm more determined than ever to keep our momentum going!

"Thank you all again – I really am beyond blessed to receive this level of support and love from all of you and I can't wait to be back."

Team-mates Nicolas Pepe and Alexandre Lacazette dedicated goals in Tuesday's win at Southampton to Aubameyang, who has scored five times in 17 league games this season.

The Gunners' win moved them into eighth place in the league, five points behind West Ham in fourth, although many of the surrounding sides in the table have games in hand.

Manchester United star Bruno Fernandes insisted he does not need to be rested after coming off the bench to secure FA Cup victory over rivals Liverpool.

Fernandes was among the substitutes in Sunday's 3-2 FA Cup fourth-round triumph at Old Trafford, where he was introduced in the second half and scored the match-winning 78th-minute free-kick.

The Portugal international has now scored 28 goals for United in all competitions since his debut in February 2020 – more than any other player for a Premier League club.

Fernandes has helped rejuvenate United, who have gone from struggling to qualify for the Champions League to topping the Premier League table through 19 matches in 2020-21.

But Fernandes dismissed claims he is tired, saying: "Tired? With 26 years old I can't be tired. If I'm tired now, when I arrive at 30, 32, I will not play.

"I will play one game in five [days] so, no, I'm not tired."

Fernandes, who dropped out of the starting line-up for Donny van de Beek against Liverpool, added: "Of course the coach knows what is better for the team and he chose to play with Donny to give some freshness to the team.

"I think it's fair enough because Donny is training really well, he's been important for us and will be more and more important in the future."

Former Sporting CP captain Fernandes is determined to lead United to silverware, following three semi-final appearances last season in the Europa League, FA Cup and EFL Cup.

Ole Gunnar Solskjaer's United, who last won the Premier League in 2012-13, also lost in the semi-finals of this season's EFL Cup.

"I don't conform with [the idea that] losing games is normal stuff," said Fernandes. "For me, losing is not normal so my mentality comes from that, you know? I always was like this. I don’t like to lose, so maybe the mentality is more like I don't like to lose.

"Also playing whatever it is, when I was playing with my friends, my brother, my neighbours, I never wanted to lose, I want to win every time. This mentality will be with me for the rest of my life, I think."

United – two points clear of neighbours Manchester City, who have a game in hand – face Sheffield United on Wednesday, are through to the FA Cup fifth round and will meet Real Sociedad in the Europa League last 32.

Fernandes said: "I came to the club because I knew this is a club who wants to win everything. So you have to be confident, you have to trust your team-mates, you have to trust yourself, and you have to believe.

"And I will believe until it's not possible. Like when I see someone get the trophy before me [only] then I will [have] lost my belief."

Gareth Bale impressed in a scoring display during Tottenham's 4-1 FA Cup win at Wycombe Wanderers, with Jose Mourinho insisting he has no worries over the Wales star's fitness.

Bale returned to Spurs on loan from Real Madrid in September but an initial knee problem delayed his second debut and he has largely existed on the periphery of Mourinho's plans in the Premier League.

He was once again called into cup action at Adams Park and produced an all-action performance, equalising after Fred Onyedinma put the Championship's bottom club ahead against the run of play.

Mourinho still had to call for the cavalry from the bench as Wycombe withstood a second-half onslaught.

Harry Kane and Son Heung-min both went close, but fellow substitute Tanguy Ndombele finished superbly for a late brace after Harry Winks' cool chip gave Spurs an 86th-minute lead.

Faltering Premier League champions Liverpool are next on the agenda for Tottenham and Mourinho suggested Bale had done his prospects of adding to a solitary top-flight start this term no harm at all.

"He looked good, taking on players, scored the goal," he told a post-match news conference.

"I never felt that he could not play 90 minutes, I never felt I had to take him off.

"The Championship is a good level. That is good. I am happy."

If Bale is concerned over whether he can make himself a fixture in Mourinho's first XI, he should look no further than Ndombele.

The former Lyon midfielder was not always trusted when the ex-Chelsea boss replaced Mauricio Pochettino last term, but he is now a player on top form and oozing confidence, as his late salvo emphatically showed.

"He is very creative. He's one of these players who can break the balance [of a game]," Mourinho told BT Sport.

"They tried to get him man-against-man. Number 18 [Curtis Thompson] was man-against-man with him.

"But he is always the kind of player who can break that. If, on the top of that, he can score a goal for us, even better."

Tottenham were forced to come from behind before securing a 4-1 FA Cup win over Wycombe Wanderers.

The Championship's bottom club stunned their Premier League opponents when Fred Onyedinma capitalised on fine work by Uche Ikpeazu.

Gareth Bale went close either side of the opener and was on hand to level in first-half stoppage time.

Spurs dominated after the break, although Jose Mourinho felt the need to introduce Harry Kane, Son Heung-min and Tanguy Ndombele - the latter sealing a place in round five with a late brace after Harry Winks' classy 20-yard chip gave the visitors the lead for the first time in the 86th-minute.

Gareth Bale must earn every minute on the pitch at Tottenham with Jose Mourinho insisting he does not give them out easily. 

On loan from Real Madrid and facing an uncertain future, Bale is yet to hit the heights since delighting Spurs fans with his return to the club in September. 

Issues with the winger's form and fitness have meant he has only started one Premier League match, while he is yet to complete 90 minutes in any competition. 

Ahead of Monday's FA Cup fourth-round tie at Wycombe Wanderers, Mourinho was asked if it would be beneficial to give Bale regular outings of between 30 and 60 minutes to build up his fitness and confidence. 

Mourinho, however, suggested performances in training held the key to his decision. 

The former Madrid head coach hopes Bale will come through this week unscathed in order to boost his chances of a long run-out against Championship outfit Wycombe. 

"I cannot give players minutes," Mourinho said about Bale. "Minutes on the pitch are not something I can give. I wouldn't go in this direction.  

"We all know the difficulties he had for a couple of seasons. We all know that he arrived injured. We all know that even this season he has been a little bit up and down with small things.  

"The most important thing is to be consistent and training without any problems. 

"When a player is consistently training high intensity without any kind of problems then the player is ready not to be given minutes but is ready to earn minutes. That to me is a different thing." 

Mourinho added: "This week, he is working every minute like everybody else at a good intensity.  

"Let's see the way he reacts to that accumulation, to that load of work. Let's see how he reacts by the end of the week.  

"If he feels - because it is also about his own feelings - that the week that he had has had a positive impact on him and his confidence, he will play the match on Monday." 

Amid reports Tottenham would not be extending Bale's loan spell for a second season, Mourinho insisted last week that no decision had yet been made.

Bruno Fernandes can fully understand Donny van de Beek's unhappiness and says his midfield team-mate's lack of playing time highlights Manchester United's strength in depth.

Netherlands international Van de Beek was handed his 10th start of the season in United's FA Cup fourth-round win over Liverpool on Sunday.

He struggled to make much of an impact at Old Trafford, however, as he touched the ball just 23 times and attempted 18 passes before being substituted with 66 minutes played.

Fernandes was brought on for the Dutchman and once again proved the difference for United by scoring a free-kick 12 minutes later to earn a 3-2 victory.

Ole Gunnar Solskjaer admitted on the eve of the game that Van de Beek is not happy with his lack of minutes and Fernandes has sympathy for the £40million close-season signing.

"Donny had a great game," he told MUTV. "Playing in the position I play, watching him he moves really good and played really well. 

"It's important for us. If I was in the position of Donny I would not be happy at all but the most important is doing what he does today, coming in and helping the team.

"We have a really good squad and we have options. If you look at the bench and the first XI today and the ones at home we have a really good squad.

"It will not be a problem if we change the team or someone is tired because we have really good players."

Fernandes has now scored 28 goals for United in all competitions since his debut in February 2020, which is more than any other player for a Premier League club.

His latest strike sets up a home tie with West Ham in the fifth round next month and, with United also top of the Premier League, Fernandes has his sights set on silverware.

"They're all important competitions for us," he said. "We have to go in the same way whatever the competition.

"We play in them all to win. Everyone knows winning the league is more special but for us players, it's about winning trophies regardless and this is a trophy we want to win."

United have now eliminated Liverpool from the FA Cup proper on 10 occasions - only the Reds themselves have knocked out a single team more often, beating local rivals Everton 12 times.

Manchester United manager Ole Gunnar Solskjaer said the Red Devils made a "statement" with their uncompromising performance in the FA Cup win over Liverpool.

United's 3-2 victory at Old Trafford was clinched by a stunning 78th-minute free-kick from substitute Bruno Fernandes, after earlier goals from Mason Greenwood and Marcus Rashford on Sunday.

A double from Mohamed Salah had kept Liverpool firmly in the game before Fernandes cracked a sublime shot into the right corner, having spent extra time honing his technique on Saturday.

What most pleased Solskjaer was how United were able to thrive while playing their natural attacking game against Premier League champions Liverpool, rather than make special allowances for the opposition.

"We've found a way we believe in, the players believe in, and we're getting stronger and stronger," Solskjaer said.

"We look at the difference from a year ago or six months back. You can't take too many big strides at one point but we're gradually, layer by layer, getting better, winning tight games, so you have the morale and the confidence of course is very good.

"It's a good feeling to play on our terms."

Solskjaer said United have previously adopted "different systems to nullify opponents", but that was not the case in this fourth-round battle.

"Of course, that's a statement to ourselves," Solskjaer added. "That's a confidence boost that we can match the best with our style of football."

Everything the Norwegian boss appears to be turning to gold just now, with United top of the Premier League and through to a fifth-round cup tie against David Moyes' West Ham.

Even the decision to start with Fernandes on the bench proved a masterstroke, regardless of the fact replacement Donny van de Beek struggled at times.

The effect of Solskjaer's decision, relayed to his players on Saturday, meant Fernandes was granted more time to practise his set-pieces ahead of the game, and how that worked out.

Since his United debut in February 2020, Fernandes has scored more goals than any other play for Premier League clubs with 28.

Greenwood (19 years and 115 days) became the youngest United player to score against Liverpool since Wayne Rooney in January 2005, while the Manchester club eliminated Liverpool from the FA Cup for the 10th time – only the latter (12 against Everton) have knocked out a particular team on more occasions.

"Whenever he starts, I tell him to go straight in [from training] and he can't do extra free-kicks," Solskjaer said.

"Yesterday, I told him he wasn't playing so he stayed out practising for half an hour, 45 minutes. It worked and it paid off."

Rashford came off in the second half with a knee complaint, and Solskjaer said the forward would have a scan to determine if there is anything to worry over.

Attacking midfielder Jesse Lingard, not part of this matchday squad and a peripheral figure this season, could yet leave Old Trafford during this transfer window.

Solskjaer said he would "sit down with Jesse and decide what we're going to do", but did not exclude the possibility of him staying, suggesting Lingard could well come back into the first-team picture.

On a day when Donny van de Beek hoped to show why he deserves more minutes for Manchester United, up stepped Bruno Fernandes to show why that simply isn't happening.

The eye-catching selection of Van de Beek ahead of Fernandes for this FA Cup clash of giants at Old Trafford was all about "rotation", according to Ole Gunnar Solskjaer.

United's manager clearly felt his team could combat a faltering Liverpool team without their star man, albeit leaving him on the bench in case of emergency.

"Donny needs to be playing games as well and it's a big game for Donny to come into," Solskjaer told the BBC.

Van de Beek has not started a Premier League game since he was hauled off with United trailing at half-time at West Ham in early December, and he might not be starting any soon either given how this game transpired.

A 66th-minute switch of the Portuguese for the underwhelming Van de Beek proved pivotal, and the delightful free-kick from Fernandes that settled an absorbing game 3-2 in United's favour was one that had been conceived on Saturday.

"I think he stayed about 45 minutes after training yesterday shooting free-kicks, so I was quite confident that he was going to hit the target," Solskjaer said.

Solskjaer, the erstwhile supersub, knew the calibre of replacement that was up his sleeve, and the rotation worked in a roundabout way. Are we looking at more proof that United's once-maligned Norwegian boss is actually a tactical master?

Liverpool's season, meanwhile, takes another negative turn.

Donny fluffs his big chance

With a mere 18 passes and 23 touches, Van de Beek was peripheral in a midfield where Paul Pogba shone and Scott McTominay fought for every ball.

The former Ajax man had a glorious early chance to stamp his mark on the game when he burst into space on the right and looked sure to dart towards the penalty area, as Edinson Cavani waited for a pass in the centre.

But no. Van de Beek paused and decided to go backwards, and the chance was gone.

This game was a world away from the Anfield snore draw seven days previously in the Premier League, yet Van de Beek largely let it pass him by.

By the time Fernandes cracked his sublime winner into the right corner, Van de Beek must have been wondering when such an opportunity will arise again.

Salah shows he must start

Like Fernandes, Salah has seen his form and contribution questioned in recent weeks, and just as United's match-winner dispelled such criticism, so did Liverpool's main man.

After all the talk about front threes, and which of these sides had the most deadly attacking trio, Liverpool boss Jurgen Klopp went with a two-man strikeforce, Salah and Roberto Firmino linking up and Sadio Mane on the bench.

Both Salah and Firmino had been substitutes on Thursday for the defeat to Burnley, but they were a combination that United struggled to contain at times here.

Salah struck twice, the first a sublime chip, and Firmino set up both. The Brazilian has now assisted Salah for 18 goals during their time together at Liverpool, the most any player has set up another during Klopp's reign.

Unlike Firmino and Mane, Salah has exceeded his expected goals (xG) in the Premier League this season, with eight non-penalty goals from an xG of 5.3, and if Liverpool are to resurrect their season, the bench is surely no place for the Egyptian.

Glorious Greenwood

Mason Greenwood has not scored in the Premier League since that West Ham game, when he helped United turn their half-time deficit around and earn a 3-1 victory.

Here he looked lively from the early stages, albeit with one too many lollipops and insufficient tasty final product until he cancelled out Salah's opener.

The way the 19-year-old ended an 10-game barren spell spoke volumes of his belief, with Marcus Rashford's sweeping pass over the Liverpool defence finding his wing twin on the right and allowing Greenwood to thump a low shot past Alisson.

With Rashford also on target, this was quite a day to savour for the hosts.

Liverpool "wanted it too much" against Manchester United on Sunday and left themselves exposed, claimed Jurgen Klopp.

On the back of their colossal home record in the league coming to an end at the hands of Burnley on Thursday, Liverpool suffered a second successive defeat as they went down 3-2 in the FA Cup at Old Trafford.

Bruno Fernandes came off the bench to score a stunning free-kick to settle a contest that delivered the quality which the league meeting between the two bitter rivals one week earlier had been severely lacking.

Mohamed Salah scored both of Liverpool's goals in an impressive return to form, with Mason Greenwood and Marcus Rashford on target for United prior to Fernandes' winner.

United had 41.6 per cent possession but managed to equal Liverpool's tally of attempts (14) and shots on target (six).

For both of United's first two goals, Liverpool were caught cold on the counter.

Klopp believes that was a result of his side being slightly overzealous in their desire to arrest a dismal run of form which has seen them win just once – against Aston Villa's youngsters – in their last seven matches across all competitions.

"There was a lot of good things and some mistakes around the goals. If you want to win here you have to be absolutely top and we were not," Klopp told reporters.

"For the first goal we had no protection, we wanted it too much. Things like this should not happen but they can happen.

"We can take things out of this game, we try to learn from every game. It's good for Mo Salah, good for the confidence. It was a tough game. We want it hard but tonight it was not enough.

"If you win a game there are negatives, if you lose a game too, but I saw the boys really, really wanted it. We had problems on the counter-attack, it was intense, but there were positives."

Ole Gunnar Solskjaer's side will face West Ham – and former United manager David Moyes – in the fifth round of the cup, while they also sit pretty at the top of the league as it stands.

After seeing his side fall behind to Salah's 18th-minute chip, Solskjaer was delighted with United's response.

"Brilliant – you know when you go a goal down, the reaction of everyone was really good," he told BBC Sport.

"We played some really good stuff, good goals, we have to defend well against them and we managed to react well and of course towards the end there were some moments but we kept them away."

Fernandes ultimately made the difference, scoring with his only attempt, while he also crafted a chance for Edinson Cavani with a wonderful cross – the experienced forward heading against the post.

"Great goal, good free-kick," Solskjaer said of Fernandes' impact. "When you leave him out like I did today, he stayed about 45 minutes after training yesterday shooting free-kicks so I was pretty confident he could score one if he got the chance.

"He's never happy with me when I tell him to go inside after training when he's playing the next day so he got some practice yesterday."

United are now unbeaten in their last eight home games against Liverpool in all competitions (W4 D4) since a defeat in March 2014.

Bruno Fernandes came off the bench to settle a thrilling FA Cup fourth-round encounter as Manchester United overcame Liverpool 3-2 at Old Trafford.

Mason Greenwood and Marcus Rashford turned the game in United's favour after Mohamed Salah had put Liverpool ahead in the 18th minute.

Salah's second of a pulsating contest levelled matters once more with Liverpool looking the more likely to prevail thereafter.

However, the introduction of talisman Fernandes proved a masterstroke as he arrowed a low free-kick into the bottom-right corner from the edge of the area to set up a fifth-round tie with West Ham.

Manchester United boss Ole Gunnar Solskjaer left Bruno Fernandes out of his starting line-up for Sunday's FA Cup clash with Liverpool.

Fernandes, who has been United's shining light since arriving from Sporting CP almost 12 months ago, was only a substitute for the fourth-round game.

This season he has scored 15 goals and supplied nine assists in 28 games across all competitions from his advanced midfield role, but there have been questions asked about his form in recent weeks.

He has just one goal and no assists in four Premier League appearances since the turn of the year.

Into the United team went former Ajax midfielder Donny van de Beek as Solskjaer decided the game presented a chance to rotate his squad, making five changes to the side that won 2-1 at Fulham on Wednesday.

Solskjaer explained why Fernandes did not start, saying on BBC One: "It's rotation in the squad.

"Donny needs to be playing games as well and it's a big game for Donny to come into.

"He's done nothing wrong when he's been around the club so I'm looking forward to seeing him in there."

Premier League leaders United also brought in goalkeeper Dean Henderson, centre-back Victor Lindelof, midfielder Scott McTominay and forward Marcus Rashford, as David De Gea, Eric Bailly, Fred and Anthony Martial dropped out.

Liverpool also showed five changes as Jurgen Klopp looked for a response to Thursday's shock 1-0 home defeat to Burnley, which ended a 68-game unbeaten run at Anfield in the Premier League.

Teenage centre-back Rhys Williams came in for the absent Joel Matip, while James Milner and Curtis Jones were selected as Xherdan Shaqiri and Alex Oxlade-Chamberlain dropped to the bench.

Sadio Mane and Divock Origi were also substitutes as Klopp gave starts to Mohamed Salah and Roberto Firmino, with the Old Trafford clash coming a week on from these two sides battling out a dreary goalless draw at Anfield in the league.

Kepa Arrizabalaga made another blunder and Timo Werner missed a penalty but Tammy Abraham's hat-trick got Chelsea past Luton Town with a 3-1 victory at Stamford Bridge.

Abraham's quickfire double put Chelsea in control early in the FA Cup fourth-round tie on Sunday, as last season's runners up seemed to be heading for a comfortable success.

Yet Kepa, brought in as one of seven changes made by Frank Lampard from Tuesday's defeat at Leicester City, enabled Luton to haul themselves into the contest when he failed to keep out Jordan Clark's effort.

Abraham's third goal 16 minutes from time ultimately set up a fifth-round trip to Barnsley, though Werner's woeful run in front of goal continued when his late spot-kick was saved.
