Man Utd v West Ham - as it happened

AET: Man Utd 1-0 W Ham!!! All over at Old Trafford and Man Utd deservedly make the last eight thanks to McTominay's 97th minute goal. West Ham played for a 0-0 and then when they finally attacked, they lacked the quality in the final third to really trouble Henderson. United only scored one, but were the much better team all the way through. Thanks for joining us and see you again soon!

Martial!!! United keep the ball through Fernandes, Fred and Martial and then Martial is denied by Fabianski!! And the ref then ends the game!

West Ham lose the ball and then Rashford tries to take the ball to the corner. He loses the ball, but United quickly win it back.

Man Utd win a free-kick in their own half and one extra minute.

Fred earns a free-kick on this near touchline.

Henderson!!!! He gets very casual and dribbles the ball around Soucek inside his own six yard box! That was risky.

Shots: 16-3, on target: 4-0.

Martial!!! He has an effort now which is saved by Fabianski.

Benrahma!!!! What a chance!!! Johnson's chipped pass finds Benrahma and he heads straight at Henderson! It was offside so it wouldn't have counted anyway. The flag didn't go up though.

West Ham sub: Lanzini on for Odubeko. A sub being subbed. He doesn't look that pleased about it on the bench.

United counter and Fernandes can't find Rashford.

Benrahma and Fredericks combine and the latter's chipped ball in is dealt with by the hosts. Just lacking that quality in the final third.

Fernandes and Cavani are not on the same wavelength there as the Portuguese is surprised by the Uruguayan's pass for him to run onto. The ball runs through to the goalie.

Martial attempts to play a through ball for Shaw which he can't quite reach.

United get us going again!!

HT in ET: Man Utd 1-0 W Ham!

The free-kick comes in, it's caught by Henderson and that's HT in ET. 15 minutes for the Hammers to score, but I think United won't lose it from here.

105+1: Johnson is fouled by Williams at midfield.

One added minute.

Benrahma fouls Rashford now.

Fernandes runs towards the box and then looks to pick out Martial, but the pass is too strong.

76% possession for the hosts in extra-time. I think West Ham will struggle now.

United attack and Martial is penalised for handball.

The Hammers go forward through Benrahma and the cross is dealt with. Moyes' men have to try hard now.

McTominay scores for Man Utd on the counter!! West Ham throw players forward, they are caught on the break through Martial, Fred's cross is only half-cleared by the Hammers and Rashford lays the ball off to McTominay who fires home!

Cavani is caught offside now.

Martial's ball in is headed away and the Hammers continue to frustrate them.

Lovely play by Martial to get past Coufal and he gets the corner.

Extra-time started!

Man Utd double sub: Shaw on for Wan-Bissaka and Williams replaces Telles.

Man Utd 0-0 W Ham!! Gone to extra-time.

90+2: Wan-Bissaka!!! Dawson heads on the corner to Soucek at the back stick and Wan-Bissaka is there to clear!! What a chance!

90+1: W Ham attack through Johnson and the ball strikes Wan.Bissaka and then goes out for a corner. The Hammers want a handball, but it looks to his chest. VAR checks and it's play on.

The Hammers threaten again and United have to clear it away.

Van de Beek strays offside again.

Very little has happened since the interval, to be honest. Just the odd moment here and there. 0-0 is very fair.

72% possession for the Hammers in the last five minutes.

Lindelof is caught on the back of the head by Soucek as he looks to head the ball towards goal.

West Ham putting some pressure on here now.

Rice wins the corner off Fred.

We've had it confirmed that Diop's sub was a concussion sub.

West Ham sub: Yarmolenko can't carry on and Odubeko is on.

Rashford!!! What an opportunity!! The cross by Greenwood is deflected the ball finds Rashford whose shot is saved by the keeper.

Quiet start to the second half and Yarmolenko is not right.

Telles is penalised for a high boot on Fredericks.

Yarmolenko has gone down here now. He has a knee problem.

Back underway here!

West Ham have used three changes, but I have the feeling the Diop one is a concussion sub. If that's the case, West Ham will still have three left and United will be able to make six changes.

West Ham HT double sub: Ben Johnson is on for Jarrod Bowen and Diop goes off for Fredericks.

HT: Man Utd 0-0 W Ham! Half-time at Old Trafford and, despite United dominating possession and territory, Fabianski has had little to do bar that fantastic save onto the post from Lindelof's header. Matic had a half chance, but little else to speak of. The Hammers have come for a 0-0 and are doing well despite losing Ogbonna to injury early on. Back for more shortly!

45+2: Greenwood counters after the Hammers had a good chance for Fornals, but the Spaniard was in two minds and the opportunity passed by.

Vital stop by Telles! Fred makes a mistake, a Hammers man plays the ball to Bowen and Telles gets back to prevent a clear chance for Moyes' men.

Telles and Van de Beek combine and the ball goes for a corner.
