Max Killman is back on his feet with a clean shirt after having his nose mopped up. It looked like he ran into Dejan Kulusevski.

VAR check after Chris Mepham misjudges the ball which lands on his arm. Play has been stopped...boos as the check reveals no penalty. This is turning into a most frustrating afternoon for the Gunners.

In-form Villa striker Ollie Watkins has only touched the ball three times in 34 minutes. Six touches for Wilfried Zaha.

Crystal Palace are 12th... but only four points above the relegation zone as things stand. They are nowhere near safe yet.

Villa are only two places above them but seven points (if they win this).

Leeds are looking to press where possible but they are happy to sit in their own half and stay compact.

More injury concern for Wolves.

Max Killman is down receiving treatment after pulling up off the ball.

Good stuff from Brenden Aaronson who drives to the byline and pulls it back for Crysencio Summerville. He's blocked off at the near post.

Another chance for Chelsea.

Ben Chilwell brings it down in the box, has the goal gaping and options to his right but he goes for neither - instead, poking it well wide.

Solly March came back on for Brighton by the way, just the one first-half injury for them so far.

One-way traffic as Arsenal win another corner. They're throwing the kitchen sink at this but cannot score. Their latest attempt is a looping header by Takehiro Tomiyasu but it's comfortably gathered by Neto.

Half a chance.

Brenden Aaronson is teed up by Georginio Rutter in the box but his shot is deflected up and over the bar.

Ruben Neves brings down Dejan Kulusevski and Wolves think the break is on but it's brought back for a foul.

Every defender's nightmare, that ball whipped into the six-yard area.

Palace have struggled with crossing situations. They need to wise up.

It's settled a little at Stamford Bridge. Chelsea are still controlling things but Leeds have managed to temper the chances slightly.

The stretcher is out for Diego Costa, who shakes his head and has tears in his eyes as he leaves the pitch at Molineux. The home fans applaud. It didn't look good.

Raul Jimenez is coming on in his place.

They've just shown a replay of Bournemouth's goal. The first Arsenal player to touch the ball in this game was Aaron Ramsdale to pick the ball out of the his net after 9,11 seconds.

Joao Felix is still shaking his head after coming so close to giving Chelsea the lead a little earlier.

However, he has been brilliant so far in this game, it is like the ball is stuck to his feet as he glides past Leeds players.

Chelsea have had many false dawns this season, starting well only to fade, but it does feel like it is only a matter of time before they score here. At the moment, Leeds can barely handle them.

Only Glenn Murray (eight) has scored more Premier League penalties for Brighton than Alexis Mac Allister (six).
