That’s the interval, and Arsenal look home and dry – but you can never write off this Leeds side. Still, it’s a long, long way back for the visitors at this rate.

That was a delightful third goal, but once again you have to question Meslier. He’s had a nightmare half. The worst half by a goalkeeper at the Emirates since Runarsson’s game against Man City in December.

It’s three for the Gunners! Bellerin had a wild shot on his left foot earlier, but shows what he can do on his right here as he finds a bit of space in the box and thrashes an effort into the near post past Meslier.

Again the goalkeeper should do better, but it’s a great finish.

So, after all that, Arsenal do score a penalty. Another one for Aubameyang. Turning into a lovely afternoon for him.

Meslier has been shaky today – he should have done better with the first goal, and the penalty was down to his carelessness on the ball. For all the talk of Bielsa’s tactical nous, you won’t win these games if your goalkeeper is making those sort of mistakes.

Aubameyang scores his 200th club career goal, making no mistake from the spot as he sends Meslier the wrong way. Superbly struck spot-kick, and Arsenal are in control.

What are you doing, Meslier?! The keeper has the ball at his feet, dallies, doesn’t clear, and Saka nips in to nick the ball and gets fouled by the Leeds No1!

No VAR needed this time, and Aubamayeng to take…

Before referee Stuart Atwell overturned that David Luiz afforded a second for a joke, shouting: “it’s a red card.” A nod to his one at Wolves last week. No luck for Arsenal here, though, as that penalty is overturned.

Arteta and staff perplexed at that decision. Arteta talking to fourth official and stating case. Consistency again surely the issue.

The referee watches the challenge back, and overturns his previous decision. No penalty for Arsenal, and both Saka and Arteta are baffled.
