Steven Alexander: Great start for Arsenal but can't keep a clean sheet so we will need another one at least.

Darren Christie: Arsenal playing with the footie equivalent of one-arm tied behind their back with Mesut Ozil on the pitch.

United come close again.

Paul Pogba involved for the first time, teeing up Fred from a long way out.

The Brazilian drills a daisy-cutter which strikes the foot of the post.

Inches.

Six of Granit Xhaka's seven Premier League goals for Arsenal have come from outside the box, including both against Man Utd.

PJ: These modern footballs are not fair to goalies at all!!! Look at how much that ball swerved in the air! Unbelievable!!

Denham: Tough being a goalkeeper with these modern balls.

As poor a showing I have seen this from Manchester United since Ole Gunnar Solskjaer took charge in December.

Not out of the dressing room yet.

Arsenal are piling on the pressure.

French striker Alexandre Lacazette drifts into the area, but his low shot is blocked by Ashley Young and loops gratefully into the hands of David de Gea.

If you're an Arsenal player now, if you get the ball anywhere near goal you take a shot. It doesn't matter how good David de Gea is, test his nerve.

Rob: Not sure what happened there from de Gea but you won't find any United fans moaning. It happens sometimes.

Richard Browne: De Gea fast asleep - collector’s item that.

Peter Collins: De Gea is a brilliant keeper, but that is a howler. He dived the wrong way for a shot that should never be going in.

Looking at it from behind the goal, David de Gea just loses the flight and got nowhere near it.

David de Gea just went completely the wrong way. It didn't move that much and it has to down as a huge goalkeeping error.

There is a little bit of swerve on the ball but it's no Roberto Carlos is it?!

Romelu Lukaku needs a miss before he can score.

The next one will find the net, trust me.

Not sure how Romelu Lukaku managed to miss that. He was only a couple of yards from goal and he's steered it onto the bar somehow. It looked easier to score.

This is a very open game. We're only 10 minutes in and both sides have had good chances.

United's first attack and they hit the crossbar.

Luke Shaw plays a glorious cross into the six yard box for the in-form Romelu Lukaku, but the Belgian's shot bounces off the woodwork.

Very ambitious effort from distance from Pierre-Emerick Aubameyang. But again it's Mesut Ozil who finds the space for him. It doesn't look like Nemanja Matic nor Fred know who should be picking him up.

All Arsenal.

Mesut Ozil pings a ball into the feet of Pierre-Emerick Aubameyang 30 yards out.

The Gunners front man spins and takes a shot on the bounce which flies a yard over David de Gea's crossbar.

Remember that turn and shot from Thierry Henry past Fabian Barthez all those years ago?

Really good from Arsenal in the opening exchanges, very impressive from the Gunners.

Sead Kolasinac is involved again freeing Pierre-Emerick Aubamenyang, but the Gabon international's cutback is over the crossbar.

Arsenal have had three attacks so far and Mesut Ozil has started every one of them.

Arsenal pushing forward and earn the first corner of the game, allowing Laurent Koscielny and Sokratis to get up top, but Alexandre Lacazette heads wide and the defenders have to jog all the way back.

Arsenal get a free-kick which is floated in by Granit Xhaka and eventually Pierre-Emerick Aubameyang's acrobatic overhead kick is sliced over.

The Gunners on top early on.
