Luke Shaw has been a menace since he's come on and another delicious cross is wolfed down by Scott McTominay.

But Sheriff keeper Maxym Koval, who has had an excellent game, spreads himself well to block.

Have we got time for a Manchester United fourth? Quite possibly.

Three minutes of stoppage time begins with a home corner after Luke Shaw's dangerous cross is slid out.

Not a lot to report at the London Stadium as we near the full-time whistle.

West Ham are going to top the group. Job Done. Three minutes of added time to come for David Moyes' side to protect their perfect European record this season.

Bruno Fernandes has been quietly excellent tonight. Another incisive pass slices open the Sheriff defence but Christian Eriksen, who's off the leash and inside the away box, can't slide in.

Harry Maguire's quiet night is somewhat ruined by a harsh yellow card. The returning United skipper is booked after he challenges Iyayi Atiemwen for a high ball.

If there were any doubts about Ronaldo's current popularity among United fans, they have quickly disappeared as he celebrates in front of the Stretford End.

Wait! There's no 'siuuuu'. Instead he stands facing the crowd, tilting his head back and clasping the palms of his hands together.

Sure that's a reference to something or other. Fifa 23 watching closely.

Alphonse Areola is quick out of his goal to beat Tonni Adamsen to a through ball. The Hammers goalkeeper has not had lots to do, but he's been ready when his side have needed him tonight.

Tomas Soucek and Declan Rice are coming on.

David Moyes isn't taking any risks. Conor Coventry and Michail Antonio make way.

Before they can, Gianluca Scamacca flashes a header over following a corner.

This is a decent spell for the visitors, but an attack breaks down with West Ham back in numbers.

Less than 10 minutes to go.

Another United free-kick and another chance for Cristiano Ronaldo to score.

Hits the wall, not the net.

Not going to be his night is it?

Yes, that was Alejandro Garnacho's final act.

A largely standing ovation for the 18-year-old after a decent first start for Manchester United.

Someone behind him on the bench rubs Garnacho's head as a sign of appreciation.

The intensity has gone from West Ham. They still have a safety net at 1-0, but they need to stay alert at the back.

Luckily Alphonse Areola is, darting off his line to smother the ball as Silkeborg threaten on the counter.

Erik ten Hag just took advantage of that break in play to come to the touchline and give Alejandro Garnacho some personal instruction.

It seemed to involve an explanation about what he wanted Garnacho to do when there was space in front of him and a defender behind.

The expressions weren't quite Pep Guardiola manic sadly.

Oh, we tell a lie. Looks like Donny van de Beek, another who is back tonight after injury, will get some minutes.

On for Garnacho? The teenage Argentine fires over from a short corner, moments after Marcus Rashford is denied a second by a smart save.

Nayef Aguerd gets 76 minutes in his first competitive appearance for West Ham following his pre-season injury.

A largely comfortable night for the £30m signing, who receives a warm reception as he leaves the pitch with a clean sheet. On comes Thilo Kehrer.

Fifteen minutes to go and the pace has slowed down somewhat.

A flurry of changes from Sheriff, but doesn't look like Erik ten Hag is tempted into any more just yet.

Cristiano Ronaldo won't be coming off until he's scored.

A brief stoppage as Sheriff keeper Maxym Koval goes down and needs some treatment.

He's been a busy boy this evening.

Twenty minutes to go.

Still just the one goal for West Ham, somehow, but they're on course to complete their objective - despite the look on David Moyes' face suggesting otherwise.

Still not sure how many Moldavans are inside Old Trafford tonight, but Sheriff almost give those who are something positive to shout about.

United keeper David de Gea is woken from his slumber to stop Iyayi Atiemwen's shot.
