Big chance for the home side to put this back in the balance!

Ianis Stoica sets up Eduard Radaslavescu in space in the middle but he drags his shot wide of the post.

Two Arsenal subs that say 'right, let's put this to bed'.

Bukayo Saka and Thomas Partey are on for Mohamed Elneny and Gabriel Jesus, who gets a bit of rest ahead of Chelsea at the weekend.

Arsenal aren't carving out chance after chance but they're not being put under huge amounts of pressure at the other end.

A 1-0 lead is fragile, though. Mikel Arteta will want that second goal ASAP.

This is going as well as David Moyes could have hoped.

He's sent out a young side, giving them experience and resting some of his front-line players and the young lads are coming up trumps.

The Hammers almost get a third as Vladimir Coufal's low shot is saved.

I tell you what, Oliver Scarles is a player.

He gets the ball wide left again in space and whips another fine low ball that just needs a touch but instead skips past everyone in the middle.

Arsenal remain in control here.

They're pushing for the second goal that would give them a cast-iron grip on the game.

Kieran Tierney nearly has his short torn right off him and ends up charging up the left wing like Hulk Hogan, his ripped top flapping around him.

The two youngest West Ham players are really trying to make their mark here.

Divin Mubama's strength ensures the ball falls to Oliver Scarles, who fires a low angled shot that deflects wide.

A fine save!

Gabriel Jesus looks favourite to score after latching on to a loose ball following a header from a corner. But Yanisk Brecher makes himself big and deflects the ball over.

Antonio Marchesano has come on for Zurich at the break.

Meanwhile, over in Bucharest, the home side have sent on Ianis Stoica, Darius Olaru and Eduard Radaslavescu.

Both games are going the way of the Premier League lads. Can Arsenal and West Ham complete the job?

We're back under way.

Manchester United

Manchester United's Bruno Fernandes, who started on the right wing, speaking to BT Sport: "Our goal for today was winning the game by a two goal difference. i think we did a great game. In the end we took more risks but it was a great win against a tough opponent.

"We knew that we had to take more risks in the second half. We did that. It meant they could get more chances because had less people defending. We didn't concede so that's another clean sheet and that's really important for us. Our main goal was to finish first. We have to fight good teams at any stage of competition if want to win it.

"I play wherever the coach needs me to play. I try my best to help the team."

On Alejandro Garnacho: "He was good but he knows we expect a lot from him. He is still only young but he is doing very well.

"A the beginning of the season he was not at his best. He didn't have the best attitude that he should have on tour. But he is deserving his chances now."

Manchester United

Manchester United boss Erik ten Hag, speaking to BT Sport:

"You do not always get what you deserve. Today we win and I am happy with that and some other things like the performance of Alejandro Garnacho, and Donny van de Beek is back in the team.

"Of course we are disappointed we didn't score two goals."

On Alejandro Garnacho: "We had problems there. Antony was out and Jadon Sancho was not available. I really hope he can keep the process going. He was a threat. If he can keep this going, I am really happy.

"It was a great finish, it was a great attack. It was really enjoyable."

On his substitutes and changes: "The aim was to bring extra offensive players in. At that moment we were too erratic. The last 10 minutes we got the ball in the box and created a good chance. We had to take risks."

Earlier, Manchester United won 1-0 at Real Sociedad. A decent victory in other circumstances, but they had to win 2-0 to win the group ahead of the Spanish side and avoid some of the teams dropping from the Champions League in the play-offs.

Here is some post-match chat from that game...

All looking good from Arsenal's point of view too.

They need a point to top the group. They are currently on course for all three thanks to Kieran Tierney's superb strike.

Fornals' goal is the difference. This West Ham team may be inexperienced in places but it has done really well.

Off the line!

West Ham are inches from a second as a big header from a corner from Nayef Aguerd takes a deflection and creeps slowly towards the goal.

Before it can cross, a home defender gets there to smash it away.

Paul: Arsenal players stay on their feet because they won’t get the penalty anyway. It’s happened so many times that they know they have a better chance of scoring by staying on their feet.

Anon: Why doesn’t VAR go back and award the penalty for the tug on Nketiah around the 30th minute? Goal wasn’t scored and clear tug.

Now then. Was Pablo Fornals actually offside when that long ball forward found him for the goal. He looked to be.

But there is no VAR in operation. And the old school officiating says it is a goal.
