Laurent Koscielny is back up on his feet but he is not right.

Still they work on Laurent Koscielny. Mesut Ozil is stripped and ready to come on but he won't be playing at centre-back...

In the grand scheme of things Arsenal have been the better side. But United have been more clinical in those moments.

Bolton are still very much in this game at 2-1, but Bristol City continue to threaten a third.

Robins midfielder Marlon Pack drives the ball across the six-yard box but Famara Diedhou can't quite connect with it. It only required the faintest of touches to go in, you feel, but Bolton survive.

Still plenty of time in this one.

It's a terrible accident. If it's just a gash, you can stitch that up and get back out there. It's just whether there's structural damage. They'll hope not, Laurent Koscielny has been pivotal since coming back from injury.

Arsenal fans really getting behind their team now. The goal right on half time has really given them the taste.

The Gunners are pressing but must beware the Manchester United counter.

Arsenal 1-2 Man Utd

Another injury problem for Arsenal as Romelu Lukaku accidentally kicks Laurent Koscielny in the head - I stress that there was no fault attached to the Belgian there. The big man actually flagged it up to the officials instantly.

It's a nasty cut though, plenty of blood.

Romelu Lukaku takes the free-kick...lashes it over!

End to end stuff. It's not a bad yellow card to take in the scenario. They'd have been told at half-time don't get caught on the counter attack.

Dave: I'll say it again, Man Utd are sooo lucky to have Romero as a number 2.

Denham: Romero would be most teams no.1

Aaron Ramsey does great again, jagging into the area on the left but the ball gets stuck under his feet at the crucial moment. United break, it's three on three momentarily and Laurent Koscielny drags him back and over for the first booking of the night.

Brilliantly open.

Half-hearted penalty appeal from Paul Pogba as he goes down inside the area, nothing given. Arsenal then break and Alex Iwobi is almost played in on the overlap but Ashley Young reads it well and clears.

Open game again!

Bristol City still lead against Bolton at Ashton Gate, but neither side has really taken the initiative since the interval as we approach the hour mark...

Bristol City are still controlling the game really but don't have the same tempo or fluency that they had in the first half.

Ashley Young pings in a free-kick as United manage to get a foot on the ball - but Nemanja Matic had strayed offside.

A definite spring in the Arsenal step, but United are well primed to play on the break with that lead. They did it well at Wembley the other week even if they did need many saves from Dave to see out the win.

Straight from kick-off! Ainsley Maitland-Niles engineers an improvised cross from the right, Aaron Ramsey is free and only a few yards out, he bends his neck to get a header away and Sergio Romero works wonders to touch it on to the bar!

What a save that is.

Here we go - Gareth Southgate is in the crowd as we get this game back up and running.

Arsenal's defence are not collective as a group. They came charging out for the first goal. Kolasinac isn't dropping back in. Arsenal look vulnerable on the counter-attack.

I'd like to see the front two play as a pair.

Will we get a goal as good as that Ryan Giggs goal in the second half? Highly doubtful.
