Cristiano Ronaldo is now the fourth player to score 100 Premier League goals for Manchester United, after Wayne Rooney (183), Ryan Giggs (109) and Paul Scholes (107).

He is the 33rd player in total (and the first from Portugal) to reach a century of PL goals.This match is 18 years and 173 days since Cristiano Ronaldo scored his first Premier League goal (against Portsmouth on 1 November 2003).

This is the longest gap between a player's first and 100th PL goal, breaking the record set by Ryan Giggs (17 years and 91 days).

It is a really good finish. Matic whips a great ball in; Ramsdale isn't sure if he should come out or not. Arsenal stood and watched, Ronaldo was the first to react.

Aaron Ramsdale nearly gets his side into bother again with a sloppy pass out.

United are on the home defence in a flash to set up an attack that ends with a blocked Cristiano Ronaldo shot.

This has got more twists and turns in it yet.

Alex Telles needs a bit of treatment following a clash of heads in an aerial challenge. It means we get at least 60 seconds breather after all that madness.

Craig Pawson comes to the screen and decides Telles did indeed foul Saka.

So it is not 2-0. But it might soon be.

Arsenal 2-0 Man Utd

Bukayo Saka cuts inside from the right and finds Martin Odegaard, who flicks the ball back to Saka to poke on for Eddie Nketiah to finish.

The striker is offside, though. So the goal won't count.

But wait... there's more... because VAR thinks there is a case for a foul on Saka by Alex Telles as he goes to poke the ball to Nketiah.

So we could be looking at a penalty here.

This is a fine game.

Massive Arsenal chance!

Martin Odegaard flicks the ball through for Eddie Nketiah in the box. He is in the clear and onside but fires his shot at a height that allows David de Gea to make an instinctive block.

Should have gone low.

Oh, so close to an equaliser!

Diogo Dalot unleashes a shot from range that beats Aaron Ramsdale but hammers against the crossbar.

They're getting closer.

Big calls for another penalty for Manchester United.

Jadon Sancho drives down the left and forces Cedric to drop to the turf in front of him. The Gunners defender appears to use an arm to block the path of the ball. Is he inside the box or outside?

It doesn't matter as neither on-field or VAR official see it as an offence.

Ross Matthewman: Fernandes is so infuriating. Just delivered a terrible cross, kicking the ball straight out of play from a great position, and he immediately blames the nearest teammate.

Manchester United have had a few chances since going behind. They're still in this.

Cristiano Ronaldo fires the latest over the bar from inside the box. It came from the right, via Anthony Elanga, who appears to be the most attractive method of attack for the visitors right now.

There's a Man Utd wall and a mini Arsenal one too.

Martin Odegaard chips his free-kick over both of them but misses the target.

This one is a foul according to the ref.

Anthony Elanga fouls Eddie Nketiah and gives Arsenal a free-kick around 25 yards from goal. The Arsenal striker looks like he might have tripped himself, though.

Man Utd's players don't look like they care enough. In the modern game, you've got to press, but they look so passive. It is so easy to get through them, there is no desire to make blocks, to head the ball. I wasn't the best player, but every game I'd try my best, I'd run around, I'd head it, I'd block it. You don't see any of that.
