HT: Arsenal 2-1 Man Utd
There have been 22 shot attempts in the first half of this match (11 for both teams).
Only once this Premier League season had a match this many shots in the first half: 22 at Brentford-Newcastle on 20 November (3-3 result).
HT: Arsenal 2-1 Man Utd
As it stands, Arsenal will go above Tottenham and into fourth in the table. Spurs take on Brentford in tonight's late kick-off.
Manchester United will be down in sixth, six points behind Arsenal, having played a game extra.
Can they complete the comeback in the second half and turn things around?

The last time Man United avoided loss in a Premier League match after trailing by at least two goals, was on 29 November 2020: a 3-2 win at Southampton after a 2-0 deficit.

You can't see this ending 2-1; both sides are frail defensively, Man Utd more so.
Every time Saka gets the ball, not only are Man Utd backing off, the fans are getting to their feet there is a real energy about the stadium. Every time Arsenal have caused problems, it has been down this right side and he's had an involvement.

Chris Palmer: Worst standard of Arsenal v United defending in my lifetime. Bring back Silvestre and Cygan.

Well, we can't grumble at that for lunchtime entertainment.
This is a great game of football.
Arsenal flew out of the blocks, took complete control, but have had their confidence knocked a bit by a Manchester United side who battled back and are far from out of this.

Ashwin R: Arteta as a player was as cool as a cucumber but Arteta as a manager is just like a dog barking from inside his yard.

And now De Gea is called into action!
Eddie Nketiah goes down in the box following a challenge but it's not a penalty. The attack is kept alive, though, and Martin Odegaard found for a fierce shot that De Gea palms away.

Save!
Arsenal look very nervy now. Alex Telles tries to take advantage with a wobbling, dipping shot that Aaron Ramsdale saves but not entirely confidently.
It all came from some awkward play at the back from the home side.

With all the VAR shenanigans, we'll have five added minutes.

Mikel Arteta never stops does he?
He's always on his feet, pointing, clapping, shouting. He looks like a man who worries. Remarkable that he's kept that hairline.

Ten Hag doesn't just have a mountain to climb he has Everest and Kilimanjaro combined to climb, defence should be top of his list for sure, but however by the sounds of it the two goals have waken United up.

United try to get in down the right again but Anthony Elanga can't quite control the pass sent his way and the ball drifts out of play.

Andrew Mitchell: United can feel hard done by VAR. Not to say that Arsenal shouldn’t have had the penalty, but it’s hard to understand how Soares blatantly handling was dismissed so quickly when Telles and Saka coming together was worthy of such extensive review.

Two more big chances for Arsenal!
The corner is only half-cleared and drops to Bukayo Saka for two attempts at goal, both of which are blocked.

Save!
Mohamed Elneny latches on to a ball 20 yards from goal and whips a shot that looks like it is creeping in the far corner until David de Gea sticks out a hand to palm the ball wide.

Manchester United are a danger to Arsenal going forward. Manchester United are a danger to themselves at the back. If they can keep the ball away from their own defence they are right in this game.
