Alan: Attitude of Man Utd players off the ball is woeful. No effort.

Anon: Man Utd don't press, they don't keep possession, they don't play with any energy or pace... just exactly what is Erik Ten Hag's style of play, I'm struggling to see any progress under him and sadly more mediocre players being bought in - worrying times!

That just about sums Manchester United up.

An attacking throw that ends up back with Andre Onana, who spends ages deciding what to do, before launching a long pass straight out of play.

That is so poor.

The lack of options and following execution are really bad.

More groans as Andre Onana dwells on a clearance. Then some boos as he boots the ball straight out of play.

Erik ten Hag glares from the touchline. The look of a concerned man.

His side are not at it here.

Concern for Arsenal fans because Bukayo Saka, who was injured in the Champions League game against Lens in France, has gone down heavily after trying to beat a defender having his ankle caught in the air. After lengthy treatment on the pitch he's hobbling on.

His teammates haven't really passed the ball to him in the last few minutes but he doesn't look comfortable. It's certainly a concern for Arsenal.

There's a slickness to Copenhagen's passing at times - especially on the counter - that United have been unable to match.

Another nice little spell of possession ends with Elias Achouri dancing around Scott McTominay before firing a low shot past the near post.

It was the wrong header from Scott McTominay, wrong part of the forehead. With his form he is expected to hit the target!

The medics have been called after Gabriel Martinelli and Djibril Sow collide just outside the Arsenal box.

Sevilla midfielder Sow looks to be badly winded after getting Martinelli full force to his stomach.

The resulting free kick is taken by Ivan Rakitic, but his cross is simply caught by David Raya.

Half chance for Scott McTominay, who rises in the box to meet a cross but heads wide after mistiming his jump a bit.

William Saliba carries the ball from the back, but his ball to the left aiming for Gabriel Martinelli is narrowly overhit.

This has not been a classic.

Real Madrid are dominating at Braga and have the ball in the net for the second time through Rodrygo, but his strike is quickly ruled out for offside.

It's brilliant play from Eduardo Camavinga who drives the ball forward and plays in Vinicius Junior.

The Brazilian, who times his run a tad too early, sets up Rodrygo for an easy tap-in, but the flag quickly goes up.

There are too many basic errors from the home side.

A mis-control or a mis-placed pass or no-one making the right run to thread a pass through to.

Manchester United should have the players to win this with something to spare but there is an overall lack of cohesion.

Saka is back on his feet and moving, albeit rather gingerly.

You can hear the Copenhagen fans singing. They've barely stopped since kick off.

Not much noise from the home crowd, who seem to be waiting for their team to give them something to get them going.

They're struggling at the moment.

Just the one goal across our six 20:00 BST Champions League matches...

Bukayo Saka is down after getting an absolute clattering from Lucas Ocampos in midfield.

He looks in a fair bit of pain and the physio is on.

There's a few grumbles in the crowd. This game isn't quite going how Manchester United had hoped it would. Copenhagen are here to give them a game. No mugs in Europe's top club competition these days.
