Tammy Abraham scored his 12th goal of the season as Chelsea beat Barnsley 1-0 to reach the quarter-finals of the FA Cup.

Abraham tucked in his first goal of the Thomas Tuchel era in the second half and also headed off the line at the other end as the Blues knocked the Championship side out at Oakwell.

A young, fit Barnsley team gave a great account of themselves on a cold night in South Yorkshire, but it is Chelsea who will play Sheffield United in the last eight.

Chelsea have now won four and drawn one of their five games under Tuchel after he replaced Frank Lampard as head coach last month, and although they were not at their best, a much-changed Blues side had enough to edge through.

Callum Brittain missed a golden opportunity to put the Tykes in front 10 minutes in when he shot straight at Kepa Arrizabalaga from close range.

Chelsea should have had a penalty when Toby Sibbick caught Abraham before making contact with the ball, only for referee Martin Atkinson to wave play on.

Atkinson was right not to point to the spot following a tangle between Mads Andersen and Abraham, before Brittain's strike looked like it might be heading in, only to deflect wide off team-mate Victor Adeboyejo late in the first half.

Tuchel replaced Andreas Christensen, who took a knock on the head, and Marcos Alonso, bringing on Antonio Rudiger and Reece James after the break following a somewhat flat first-half display.

Barnsley showed more intensity than Chelsea as they pressed the Blues high up the field, although the visitors' Callum Hudson-Odoi flashed a shot wide after cutting in from the left at pace.

Rudiger then headed Hakim Ziyech's free-kick just wide after 63 minutes, but Abraham broke the deadlock when he tapped in a James cross a minute later, with the hosts feeling the flag should have gone up.

Home substitute Michael Sollbauer almost scored with his first touch, but alert Chelsea striker Abraham headed off the line as Barnsley were unable to force extra-time.

Manchester City and Manchester United have been handed away draws against fellow Premier League sides in the FA Cup quarter-finals.

City, who won their sixth FA Cup in 2018-19 but were knocked out in the semi-finals by eventual victors Arsenal last season, will play Everton at Goodison Park.

While City claimed a serene 3-1 win over Swansea City in the fifth round on Wednesday, Carlo Ancelotti's team overcame Tottenham 5-4 after extra-time in an instant FA Cup classic.

The teams will have a dress rehearsal for the last-eight clash on February 17, when they face off at Goodison in a Premier League match which was due to be played in December but had to be rescheduled due to a coronavirus outbreak at City.

Like their local rivals, United also fell short of reaching last season's final, going down to Chelsea in the last four.

United beat West Ham 1-0 after extra time on Tuesday and now face a trip to face Leicester City at the King Power Stadium. Brendan Rodgers' Leicester side are flying high in the Premier League along with United and leaders City, who are five points clear of their neighbours at the top.

Last season's runners-up Chelsea went into Thursday night's match at Barnsley knowing the winners would be rewarded with a home tie against Sheffield United, who beat Bristol City at the last-16 stage.

The other quarter-final tie throws up a south-coast clash, with Southampton travelling to Bournemouth.

Games are due to be played across the weekend of March 20 and 21.

FA Cup quarter-final draw in full:

Everton v Manchester City
Bournemouth v Southampton
Leicester City v Manchester United
Barnsley or Chelsea v Sheffield United

Jose Mourinho expressed surprise over Gareth Bale ruling himself out of Tottenham's FA Cup fifth-round defeat to Everton.

Spurs took their hosts to extra time in a wonderfully chaotic game, eventually falling 5-4 to Bernard's 97th-minute winner.

Davinson Sanchez gave the visitors a third minute lead a Goodison Park and completed an unlikely brace to make it 3-3 before the hour - Erik Lamela having reduced the arrears after Dominic Calvert-Lewin, Richarlison and Gylfi Sigurdsson were all on target during a crazy seven-and-a-half-minute spell.

Harry Kane came off the bench to net Tottenham's second equaliser, Richarlison having brilliantly doubled his tally, although Bale was not among the options on the bench to bolster Mourinho's attempts to save the game.

"I think it’s better for me to say," he said at a post-match news conference when asked to explain the Wales star's absence.

"So, we played against West Bromwich on the Sunday and he didn't play. On Monday, I was a bit surprised by him wanting to have a scan because he was not comfortable with some muscular area.

"So, he didn’t train on Monday and then on Tuesday he trained with the team but I was informed that his desire was to work with the sports scientists for a couple of days to strengthen that area. That's the reason why he’s not here.

"I don’t think it’s an obvious, clear injury. I would say he feels uncomfortable. Because of that he could not be 100 per cent, but I don’t think an injury."

Asked to elaborate further on whether Bale had disappointed him, Mourinho replied: "This is Everton post-match and Gareth was not here. The only thing I can say is I am being completely open and honest."

The incident marks another unhelpful chapter in Bale's as-yet deeply underwhelming return to Spurs on loan from Real Madrid, with the chances of a permanent switch back to north London looking increasingly remote.

A scorer in two of his four Champions League final successes at Madrid, fitness problems dogged Bale over recent seasons as he fell out of favour with Zinedine Zidane.

The 31-year-old has four goals in 16 appearances for Spurs this term, although only two of his six Premier League outings have been starts.

Matters at the other end of the pitch look to be a more immediate concern for Mourinho ahead of Saturday's trip to face in-form Premier League leaders Manchester City.

"I enjoyed the way we played when we had the ball from the first minute," he told BT Sport after the breathless affair on Merseyside. "We had a great dynamic, great movement and great character to fight against incredible mistakes

"But attacking football only wins matches when you don't make more mistakes than what you create.

"We scored four goals and four goals was not enough.

"It was the mouse and the cat. The mouse was our defensive mistakes and the cat was trying to compensate for that and playing very well."

Spurs must now lick their wounds after a punishing encounter, having seen City rotate their XI and saunter to a 3-1 win in their own last-16 tie at Swansea City earlier on Wednesday.

"Of course, City are great team, they rested a big percentage of their team," Mourinho added. "We have this situation but you can't cry."

Pep Guardiola expressed his pride after Manchester City made history with a 3-1 victory over Swansea City to cruise into the FA Cup quarter-finals

The imperious Premier League leaders outclassed the Championship promotion hopefuls at the Liberty Stadium, where they eased to a 15th consecutive win – a record for an English top-flight club.

City's latest dominant victory saw them better runs of 14 in a row set by Preston and North End in 1891-92 and Arsenal in 1987, keeping them in contention for to win silverware on four fronts.

Kyle Walker opened the scoring in the first half before Raheem Sterling slotted in his 12th goal of the season early in the second half and Gabriel Jesus finished brilliantly a few minutes later.

Morgan Whittaker pulled a goal back with a sweet left-footed strike after City's Spain midfielder Rodri limped off with an injury, which Guardiola is hopeful is not serious.

The City boss was full of praise for his players after the juggernaut rolled on in Wales.

Asked about setting the record, the former Barcelona and Bayern Munich boss said: "It is a message for ourselves. We came to win, that was the most important thing.

"We cannot deny how pleased and how proud we are to break this record from a long time ago. Records are there to be broken.

"It is not easy in the modern era to do 15 games in a row. We are happy for our club."

Guardiola added: "I had a feeling that they would create chances, they were dangerous up front. They were so aggressive but we controlled the game and we created a lot of chances but could not convert."

The Spaniard did not appear too concerned about Rodri's injury and revealed Ruben Dias was absent due to illness, while Fernandinho did not feature as he has been troubled by a quad niggle.

Guardiola will be hoping they will recover in time for a Premier League encounter with Tottenham at the Etihad Stadium on Saturday.

Manchester City made history on Wednesday as they cruised to a routine 3-1 FA Cup fifth-round victory at Swansea City.

It was the 15th consecutive win across all competitions for Pep Guardiola's Premier League leaders – setting a new record for any top-flight team in English football.

Sunday's comprehensive 4-1 triumph over Liverpool at Anfield brought them level with Arsenal's 1987 vintage and Preston North End back in 1892, who won 14 in a row.

Goals from Kyle Walker, Raheem Sterling and Gabriel Jesus in Wales ensured City now hold the record outright.

In 2017-18, they prevailed in 20 consecutive matches, although there was a penalty shoot-out win over Wolves in the EFL Cup during that run and Opta classifies such matches as draws.

Given their recent record from the spot, it is perhaps handy that City have not required penalties in their current streak.

Here, we look at the numbers behind a dominant run unprecedented in scope.

Gundo in the goals

Sterling scored the goal that set City on their way into the record books, netting decisively in a 1-0 win at Southampton on December 19.

His goal at Swansea takes him to six in 10 starts during the period in question, the same as England colleague Phil Foden, who has played 905 minutes to Sterling's 856.

But it is Ilkay Gundogan who leads the way. The Germany international's brace against Liverpool improved upon what was already the most prolific season of his professional career.

In 13 appearances and 12 starts during the winning run, Gundogan has eight goals at an average of one every 124.5 minutes.

Jesus had to reckon with a positive coronavirus test during City's prolific stretch, although he now has five goals from seven starts, with a strike every 139.8 minutes second only to Gundogan in terms of frequency.

Kev the creator

PFA Players' Player of the Year Kevin De Bruyne was typically influential before suffering a hamstring injury during last month's 2-0 win over Aston Villa.

Despite being restricted to eight appearances and 621 minutes on the field, his five assists are more than any of his team-mates have managed during this period.

Foden, Bernardo Silva (who also has three goals) and defensive midfielder Rodri are up next on three assists.

Extra time on the pitch has allowed Foden to rack up 28 chances created, ahead of De Bruyne with 24.

Gundogan's all-round importance is highlighted by his 21 opportunities laid on for others, while Joao Cancelo and Riyad Mahrez have crafted 18 and 17 respectively. All three have two assists apiece.

Dominant Dias

Ruben Dias was the only ever-present during the winning run until Guardiola allowed him to sit out the trip to Swansea.

The Portugal centre-back has been a transformative presence since joining for a club-record £62million from Benfica last September and was involved in nine clean sheets over the course of the 15 matches – one more than his centre-back partner John Stones and first-choice goalkeeper Ederson.

Dias' 21 interceptions are the most during this time from any City player, as are his 1,141 passes at a completion rate of 92.81 – better than any colleague to have played three games or more.

Headed clearances and aerials won are also categories where Dias performs strongly, although Rodri leads the way here with 18 and 41 respectively.

The Spain international has won 31 one of his aerials, level with Aymeric Laporte and no one can better his 27 tackles – a stock in trade for a man operating at the base of the midfield.

Rodri's importance to the cause means the sight of him limping off during the second half at the Liberty Stadium could compromise City when the look to swagger on this weekend against Tottenham – the last side to beat them competitively, 23 matches ago.

In-form Raheem Sterling scored his 12th goal of the season as Manchester City cruised into the FA Cup quarter-finals and made history with a 3-1 victory at Swansea City.

Pep Guardiola's irrepressible side eased to a 15th consecutive win - a record for an English top-flight club - at the Liberty Stadium to stay in the hunt for an unprecedented quadruple.

Kyle Walker opened the scoring with a cross and two goals in the space of three minutes early in the second half put the Premier League leaders out of sight.

Championship promotion contenders Swansea were outclassed as the City juggernaut rolled on, although they did suffer a blow when Rodri was forced off with an injury before Morgan Whittaker pulled a goal back.

Jesus received treatment on his ankle early on, but was able to continue and the striker missed a chance to opening the scoring when he steered Benjamin Mendy's cross wide.

Swansea were chasing shadows as City dominated, knocking the ball around with a swagger, and Ferran Torres' shot from a tight angle was brilliantly tipped wide by Freddy Woodman.

Woodman was beaten on the half-hour mark, though, when Walker's centre from the right evaded everybody and found the far corner of the net.

Marc Guehi nodded wide at the other end in a rare Swansea attack, but an unmarked Sterling finished clinically when he was well picked by Rodri two minutes into the second half.

Swansea were caught out again soon after, with Jesus controlling a clever cushioned header back across goal from Bernardo Silva in an instant and swivelling to fire home with his left foot.

Joel Latibeaudiere somehow denied Mendy a tap-in with great last-ditch defending and Rodri limped off before Whittaker superbly gave the hosts a consolation, drilling in left-footed for his first Swansea goal.

Chelsea boss Thomas Tuchel is delighted to have the chance to finally work with N'Golo Kante, a midfielder who "makes teams better".

Due to a hamstring injury, Kante has made just two substitute appearances since Tuchel replaced Frank Lampard in charge at Stamford Bridge last month. 

However, he has been deemed fit enough to start Thursday's FA Cup tie with Barnsley and Tuchel has talked up the qualities of the France international, who was strongly linked with Paris Saint-Germain during the German coach's time in charge at the Ligue 1 club.

"I think N'Golo fits into any manager's plans on the planet. I was desperate to have him in my teams [in the past]," Tuchel told reporters. 

"I am so happy to have him back again. We put him on the pitch against Tottenham and he helped everybody on the pitch, which is what he does. 

"To see the guy live, to see how he works, how humble he is, the quality he gives to the team. I am so humble to be his coach. He will start tomorrow." 

Kante has made 26 appearances in all competitions this term, 19 of which have come in the Premier League. 

The former Leicester City player ranks particularly high for interceptions - only six players in the division to have played at least 13 games have managed more per 90 minutes than Kante's average of 2.32. 

For all of the midfielder's undoubted quality, though, keeping him fit is now the biggest challenge for Tuchel. 

"I'm not concerned about any more injuries because I feel the support and quality of the medical department," he said. "We can manage his minutes and workload and take care of him. I'm not concerned about his quality.  

"What I see on the pitches here at Cobham is, how can I put it, everything I expected - and I expected a lot because I am a huge fan of him. 

"I can see the input he has on teams. He makes teams better. He has the mentality of a water carrier but on such a high level." 

Tuchel also confirmed at Wednesday's pre-match news conference that Hakim Ziyech will play a part against Championship side Barnsley. 

Ziyech's first season at the club has been hampered by injuries and Tuchel has challenged the Morocco winger to regain the type of form he displayed at Ajax. 

"Hakim is another one who hopefully tomorrow we will see the best of him," the German coach said. "We count on Hakim to do something different, no doubt about that.  

"He has lots of quality and we count on him like everyone else. He has had a good training week and will have the chance to show the same quality he shows in training." 

"For me it's clear he needs to adapt to this kind of football, this kind of league. He's come from a strong Ajax squad, but they were the benchmark in the league. 

"And it's not the same intensity and it's not the same competition as it is here. But he's adapting, and he has the certain quality to decide matches and the certain quality to do the unexpected." 

Thiago Silva remains on the sidelines with a hamstring problem, although Tuchel provided a positive update on the veteran defender's injury. 

"He feels better and better, which is good, and he's getting the right treatment," he said. 

"One thing we can be sure of with Thiago is that he will be spending every minute available to him to speed up the process of healing. It is a muscle injury, though, so we cannot force it and we will wait for Thiago."

Chelsea have been eliminated from just two of their previous 54 FA Cup ties against opponents from a lower division, though one of those instances was against Barnsley, back in the 2007-08 season.

"We play every competition to win it," Tuchel said. "Every round in a cup competition is the most important round.

"It's an elimination game so we have to be totally focused and on point tomorrow when the match starts. Winning the competition would be huge. It's one of the most prestigious cups in the world and it's played at Wembley. 

"Even as a little boy in Germany, with no internet or sports channel, you know the words Wembley for sure. It's a big, big game to play in and a big goal to achieve. But tomorrow is the most important game."​

Manchester United's players must demand success of each other in order to win their first silverware under Ole Gunnar Solskjaer, according to captain Harry Maguire. 

Solskjaer's side advanced through to the quarter-finals of the FA Cup on Tuesday, recording a 1-0 extra-time win over West Ham thanks to Scott McTominay's strike. 

It was the Scotland international's seventh goal in 30 appearances for the club this season - as many as he managed in 84 outings in previous campaigns. 

United also have a Europa League last-32 tie with Real Sociedad to come later this month and are five points behind leaders Manchester City in the Premier League, albeit having played a game more. 

After reaching the semi-finals of three competitions last season, as well as losing at the same stage to City in the EFL Cup last month, Maguire is determined to get over the line this time around. 

"Last season, it was disappointing to lose in the semi-finals like we did, but we've got to win trophies," he told MUTV. 

"We've got to demand that of each other. We do. We demand that we win trophies and it's vital the team starts winning trophies, for the club and the fans as well."

United's clean sheet against West Ham was their sixth in 10 matches and Maguire felt his side were good value for the win at Old Trafford. 

"We got there in the end and we deserved it," he said. "We felt comfortable on the pitch.  

"I felt in the first half we played with intensity and dominated the game, played the game in their half and had chances where we should be one, two, three up." 

Victory for United was the ideal response to Saturday's 3-3 league draw with Everton, a defensive display Maguire concedes cannot be repeated. 

"When we've conceded, we've conceded too many - when we concede one it seems to be two. It was three against Everton. That's not good enough for this club,” he said. 

"We were disappointed at the weekend. We felt we deserved the three points but we couldn't feel sorry for ourselves.  

"We knew we had to come here tonight and bounce back and get that momentum back on our side ready for Sunday [against West Brom]." 

The Red Devils have won their last nine FA Cup matches at Old Trafford - their joint-longest home winning run in the competition, equalling their nine in a row between 1908 and 1912. Maguire is hoping they will get to play at their own ground again when the draw for the last eight is made on Thursday. 

"Yes, of course. We love playing at this ground, and we've got to make it tough for people to come here and get results," he said.  

"We need to get better and we seem to have improved a little of late. But no, obviously, we want a home game. 

"We fancy our chances against anyone. We just need to look after ourselves, perform well and assure that we start winning trophies at this club."

Jose Mourinho has explained the reasons behind leaving Eric Dier out of his Tottenham side for the 2-0 Premier League win against West Brom.

Dier had started 19 of Spurs' 21 league games before the Portuguese coach named the England international centre-back on the bench for the match against the Baggies.

The defensive partnership of Toby Alderweireld and Davinson Sanchez helped Spurs to their first clean sheet in seven matches as the North Londoners snapped a run of three straight defeats.

And Mourinho revealed Dier had suffered a loss of confidence after being one of a number of players to make individual mistakes during Tottenham's recent run of sketchy form.

Dier's positioning was questionable as Roberto Firmino scored Liverpool’s opener in the 3-1 win at Tottenham last month and, after being dropped for the next game against Brighton and Hove Albion, Dier came back to concede a penalty in the 1-0 loss to Chelsea.

"Players have moments," Mourinho said. "They can be very good, they can be strong personalities, they can be experienced, they can cope with a mistake but in the end, they are men. And they feel more than anyone else these little moments of confidence, of crisis.

"I have to admit that recently our team makes little important mistakes that are punished in terms of our results.

“And Eric was there, he was one of them. They feel it. And I believe confidence, that drops a little bit.

"But great personality, a team guy, as happy as we were when we won on Sunday. A guy that loves it here, a guy that is loved by the team-mates, a guy that I trust. And he will be back to normality and his normality is to play and be solid."

Mourinho must now decide whether to recall Dier for Wednesday's FA Cup fifth-round tie against Everton, ahead of a league game against Manchester City on Saturday.

The Spurs coach confirmed Sergio Reguilon and Giovani Lo Celso will miss the trip to at Goodison Park, while Serge Aurier is a doubt.

Ole Gunnar Solskjaer believes the pain of the late collapse against Everton inspired Manchester United to edge past West Ham in the FA Cup fifth round.

Scott McTominay's goal, seven minutes into extra-time, earned United a 1-0 win over the Hammers in a match the Red Devils dominated, leading the shot count 17-3.

Three days earlier, Solskjaer's side let a 2-0 lead slip and then conceded a stoppage-time equaliser in a 3-3 draw against Everton that dented their Premier League title bid.

Following some soul-searching after dropping the precious points at Old Trafford, Solskjaer believes United responded in the best way possible to advance to the FA Cup quarter-finals.

"We needed to have a good result and a good feeling today because we were low after the Everton game. It's hard to take but they were really focused and did the job," Solskjaer said.

"Of course you want to win every game. We want to challenge and we want to go to the final. That's what we're here at Manchester United for.

"Sometimes you're lucky with draws in the cup – we haven't been that lucky – but obviously we move another step closer to the final."

Phil Foden must be "calm" and "humble" as the plaudits flow his way, according to Manchester City manager Pep Guardiola.

Foden completed the scoring in Sunday's 4-1 win over Premier League champions Liverpool at Anfield, having also had a hand in each of Ilkay Gundogan's two second-half goals.

The 20-year-old attacking midfielder has 10 goals for City in all competitions this season and has played an integral part in them establishing a five-point lead at the top of the table.

However, Guardiola was critical of Foden's performance in the false nine role before half-time on Merseyside and, speaking ahead of Wednesday's FA Cup trip to Swansea City, said he felt Raheem Sterling was City's standout weekend performer.

"I said to [Foden], 'Don't read much, don't listen much, keep your feet on the grass and keep going'," Guardiola said, before waxing lyrical about Sterling after the England star won a penalty and scored a close-range header against his former club.

"Nobody talks much about Raheem and, at Anfield, Raheem made his best game of the last two months. By far.

"He was key in the first goal, for the penalty in the first half. Every action he made was decisive in the final third.

"Of course Phil was so important in the goals, especially in the fantastic last one.

"But Raheem was fundamental for us and hopefully, because he was a little bit not in the best form in the last month, he can continue to maintain the level he played at Anfield."

Foden will be reunited with Steve Cooper on Wednesday when Guardiola's City chase an English record - a 15th consecutive win for a top flight team.

The Swansea boss coached England to success in the 2017 U-17 World Cup, where the young Mancunian was named player of the tournament.

From that point, Guardiola has faced repeated calls to grant the playmaker more minutes at City.

A strand of post-match analysis at the weekend argued the former Barcelona boss had nurtured his latest star perfectly, but Guardiola does not necessarily view it that way and also stated Foden should not consider himself an automatic selection.

"I didn’t plan to handle the way we did it with Phil," Guardiola said. "Sometimes he played and he didn’t deserve to play.

"Normally we want to increase and talk a lot, a lot, a lot about Phil but after that we'll punish him, you know? For one mistake in this private life, we know exactly what happened [Foden was sent home from England duty last September for breaking coronavirus protocols].

"Now it's just [about being] calm. I know Phil is ready to play, His physical condition is extraordinary.

"I will handle it the same way and have handled it. When I believe he can help us he is going to play; when I believe another one deserves to play he is not going to play."

Indeed, with Foden the toast of the present moment in English football, Guardiola challenged him to turn a rich vein of form into the sort of longevity that separates the best from the rest.

"He has to be calm and understand tough periods will come. It depends on him being humble and his love for the game," Guardiola added of a player who recently brought up 100 senior appearances for City.

"We’ll see if he can handle it. Now the people expect him every game to do exceptional things, this is the most important thing.

"It's difficult to play 100 games but the important thing is to do 100 more and 100 more at this level. This is the toughest.

"This is why the best players did not do one action at Anfield; they play five years in a row, being consistent, not injured. Playing, playing, playing.

"This is the next target for Phil, maintain there as high as possible, as much and as long as possible.

"It depends absolutely on him. Hopefully he can do it."

Manchester United eventually saw off West Ham 1-0 after extra-time to reach the quarter-finals of the FA Cup, substitute Scott McTominay getting the winner at Old Trafford on Tuesday.

Ole Gunnar Solskjaer took the opportunity to give a few United fringe players opportunities to impress but ultimately had to turn to his regulars on the bench, with McTominay the one to make the difference.

United were frustrated in the first half as they struggled to make the most of their dominance over a West Ham side who offered very little in attack, with Victor Lindelof going closest for the hosts when denied by the upright.

Aside from United managing fewer shots, the pattern of the match hardly deviated after the break and it was no surprise to see it remain goalless at the end of the regulation 90 minutes.

But the hosts' superiority told in the end with West Ham unable to cancel out McTominay's 97th-minute strike.

It quickly became apparent that West Ham's plan was to pack their defence with as many players as possible and it was nearly undone just 11 minutes in, but Anthony Martial was denied by a crucial Angelo Ogbonna intervention that resulted in the Italian sustaining an injury.

But United's best chance fell to Lindelof in the 27th minute, his header from an Alex Telles corner taking a slight deflection before Lukasz Fabianski tipped it on to the post.

West Ham lost Ogbonna's replacement Issa Diop – who had clashed heads with Martial – at half-time as the recently introduced concussion substitution was used for the first time in English football, and they soon saw Andriy Yarmolenko forced off as well, former Manchester United trainee Ademipo Odubeko replacing him.

United wasted another chance a minute before Yarmolenko's exit, as Fabianski rushed out to thwart Marcus Rashford after Mason Greenwood's low cross was deflected through.

Extra-time was inevitable despite the likes of Bruno Fernandes and Edinson Cavani coming on, but a penalty shootout was not necessary, with McTominay running on to Rashford's smart lay-off and rifling a low volley into the bottom-right corner.

West Ham made the first concussion substitute in English football during their FA Cup fifth-round game at Manchester United.

Issa Diop - himself an early replacement for the injured Angelo Ogbonna at Old Trafford - clashed heads with Anthony Martial towards the end of a goalless first half.

Ryan Fredericks emerged for the second period and West Ham announced via their Twitter account that the change was a concussion replacement.

Last month, the Premier League and the Football Association approved a trial allowing teams to make a maximum of two additional substitutions in the event of players suffering head injuries and showing symptoms of concussion.

Last weekend was the first time Premier League clubs had the option of making such changes, although none were required.

Teams participating in the Club World Cup can also make concussion substitutions, although FIFA is allowing just one additional change.

Amad Diallo has been named among the Manchester United substitutes for the first time in Tuesday's FA Cup meeting with West Ham.

Diallo, 18, was signed subject to a medical and international clearance in October, before his move from Atalanta was ratified at the start of January.

The winger could reportedly cost United up to £37million despite playing only a handful of time for Atalanta prior to his move.

Diallo's adaptation period has involved a couple of games for United's under-23s, but it was clear on the evidence of those two outings that his ability is a level above.

The Ivorian scored three goals and set up another three across two matches against the second teams of Liverpool and Blackburn Rovers – the respective games ending 6-3 and 6-4 to United.

His next aim will be to make his debut against the Hammers, having been named on a strong bench that also includes Luke Shaw, Bruno Fernandes and Edinson Cavani, among others.

As for the United XI, there are rare starts for Donny van de Beek, Alex Telles and Dean Henderson, while Anthony Martial joins Marcus Rashford and Mason Greenwood in attack.

West Ham are without United loanee Jesse Lingard, who is ineligible.

Jose Mourinho is adamant Dele Alli still has a role to play at Tottenham and he could return from injury in Wednesday's FA Cup clash with Everton.

Alli has not played for Spurs in any competition since the 5-0 cup win over non-league Marine on January 10, with the attacking midfielder suffering from a muscular injury.

Before that, the 24-year-old had fallen badly out of favour at Spurs, with his four Premier League appearances this term amounting to just 74 minutes.

He was strongly linked with a January exit, as Paris Saint-Germain – now coached by Mauricio Pochettino – were said to be interested, but a move never materialised.

Therefore he has been tasked with recapturing the form from his early days at the club – Alli's 63 top-flight goal involvements was bettered by only six players across his first three seasons in the Premier League.

He was proving a real weapon for Spurs in his role behind Harry Kane, and his 26 assists over the same period was the fifth highest in the division – Alli found such consistency despite being significantly younger than those he was competing with.

His Spurs career now appears to be at a crossroads, but Mourinho insists there is a way back for him.

"Dele trained yesterday with the team and well," Mourinho told reporters on Tuesday. "Long time away, couple of weeks no training with team and recovering.

"Can he play tomorrow? Well, he's not injured but I'm not sure he can. Can he help us? I believe he can. In terms of having Dele on the bench to come for a few minutes to try to help the team, is that possible? I have to speak with him but I believe he can."

When asked if anything had changed for him to sound optimistic for Alli, Mourinho said: "Nothing changed. He's not injured. He's not injured, he can train with the team.

"He went through a process of not training and trained with the sports science people and then jumped to team work, which he did yesterday for the first time.

"Nothing changed, what maybe changed is the speculation around him because in this moment everybody knows that he's a Tottenham player and he doesn't go to any place. So probably the end of the speculation will be the end of the questions.

"He can train and he can try to help the team because this is what we want. It's what we need. We need players to help the team. Hopefully he can do that.

"In a normal situation he wouldn't even be considered for tomorrow, but with the injuries we have with so many matches we have, maybe we have to accelerate his process and maybe we can.

"But of course, I want him to be fully on board and to agree and that depends on his feelings. But if he can be on the bench tomorrow and to come for 10 or 15 minutes to help the team, that would be good for us."

Kane returned from an injury of his own in the weekend win over West Brom, getting himself on the scoresheet, and Mourinho confirmed the England captain got through the 90 minutes with no major issues.

"No bad reactions, he played well as you could see. No problems, at least no big problems," Mourinho added. "Again, we need to go player by player, on two days between West Brom and Everton, we go player by player to have their feelings and discuss with them to see the best options.

"Of course, we want to go with a strong team [against Everton] but at the same time we don't want to create problems with the future of the players."
