Dear me. I've got no idea why he doesn't just clear that.

He should just hit it with his left foot, just put his foot through it.

He makes a real mess of it and it's game over. It's poor play and he's put his team in a really bad position.

What is it with keepers this weekend?

Illan Meslier dithers after a back-pass by Liam Cooper and Bukayo Saka is straight on to it.

Meslier and Saka get in a tangle and this time the referee does award a penalty.

Mikel Arteta is not happy at all with Stuart Attwell's decision. The normally composed Arsenal boss has flung his arms in the air when the referee decided against awarding the penalty.

When you look at it head on, there's not that much contact. It's like an upper body lean.

It's clumsy - this is one of those decisions that's subjective.

Attwell takes a good look at the incident again before deciding it's NOT a penalty.

Bukayo Saka goes sprawling inside the box after Laim Cooper's challenge.

Arsenal arms go up for a penalty? VAR are looking at this and Stuart Attwell is now heading for the pitch side monitor to take another look.

Mikel Arteta will like what he is seeing. Arsenal are dominant but Leeds - as they showed with the attack which lead to Jack Harrison's attempt - are very much in this.

Arsenal need a second goal to settle nerves while Leeds look good on the counter. This is an intriguing contest.

Big chance for Arsenal to double their lead but Luke Ayling throws himself at Pierre-Emerick Aubameyang's attempt from inside the area.

That's a very important block.

You never see any change in Leeds when they concede.

They could go 1-0 or 2-0 down - you don't see heads drop. They stick to their system.

That's more like it.

A terrific ball forward by Jamie Shackleton finds Raphinha in the penalty area who squares to Jack Harrison to fire straight at Bernd Leno.

Much better.

Look away now Leeds fans...

Leeds have won none of their last 30 matches in London when conceding first, since a 2-1 win over QPR in May 2011.

Saka does really well to win back possession and is then fouled again from behind. He's the Jack Grealish of the Arsenal team isn't he?

Bukayo Saka is causing Leeds all sorts of problems with his pace. He's just won another free-kick but Arsenal quickly lose possession. It's gone a little bit quiet since the goal. Marcelo Bielsa is in his trademark crouching position observing every kick.

What have Leeds got up their sleeve?

Marcelo Bielsa's side have been pegged back by their dominant opponents but suddenly space opens up for Mateusz Klich about 20 yards out.

High and wide.

Daniel Cheng: That was classic Aubameyang cutting in from the left. Welcome back captain!

Arsenal have a spring in their step.

They look energised with Pierre-Emerick Aubameyang back in the side.

They've take the game to Leeds from the start and they deservedly have the lead.

These are the moments of class Arsenal have been missing. It really was a brilliant finish. He was on the left and came on to his right foot - what he does so well.

Instead of aiming to the far post he cuts it into the near post - really clever.

Great cross by Jack Harrison which falls nicely for Patrick Bamford whose header is straight at Bernd Leno. A really bright move which allowed the visitors a first clear sight of goal.
