Change for Arsenal.

Aaron Ramsey replaces the disappointing Mesut Ozil.

One way traffic at the moment, it's been all Chelsea for the last 10-15 minutes.

Zred: When Chelsea bring in Hazard why don't Arsenal bring in Ozil to counter that

Eddie: Good to see Mustafi reading Ozil the riot act for not putting pressure on Chelsea midfield players!

Chelsea piling on the pressure, can they find a third?

Chelsea boss Maurizio Sarri looks stressed standing on the touchline.

Someone get the man a ciggy.

Luke: What is worrying for Arsenal is that this defensive performance is against a side with Ross Barkley in the team.

Pamela Smith: I don't know why Arsenal just loves missing chances. You don't do that when you are up against your rival.

Jolasun: Shkodran Mustafi and Granit Xhaka has no place in the team. It would be good for the coach to play Alexandre Lacazette alongside Pierre-Emerick Aubameyang.

Pinball inside the Arsenal area, as they get peppered with shots from Chelsea.

The Gunners are retreating and are clinging on.

Here come the Chelsea changes.

Ross Barkley and Willian make way for Mateo Kovacic and star man Eden Hazard.

Unai Emery is a figure of perpetual motion - constantly cajoling and encouraging his Arsenal players. Chelsea's fans are now chanting for the introduction of Eden Hazard, who is out warming up.

Pierre-Emerick Aubameyang in on goal...and a smart outside-of-the-foot finish into the net.

Offside.

Just.

Superb stuff from Ross Barkley.

He skips past the challenge of two Arsenal players, chips the ball in between the challenges of another two, before drilling a low shot which is brilliantly tipped wide by Petr Cech.

Again it's easy for Chelsea to break clear.

Arsenal get away with one.

Sub Lucas Torreira gives the ball away and Pedro releases N'Golo Kante, but the Frenchman's low shot is brilliantly blocked by the sliding challenge of Sokratis Papastathopoulos.

Better from Arsenal, picking up where they left off in the first half.

Nacho Monreal meets Hector Bellerin's cross towards the back post, but the header is blocked.

Pascal: TORREIRA!!! Finally!

Howepundit: Emery doesn't waste time with substitutions!

Paul: Chelsea need Hazard and Moses on now!

Pedro has already got one but this effort is not so good, lofted over the bar from the edge of the box.

Where's the follow up??

Pierre-Emerick Aubamenyang with a lovely guided ball across the six yard box, but no Arsenal player is busting a gut to get on the end of it.

Ted: I get the feeling that there’s at least another three goals in this game.

Nas: This game takes me back to the great days of 20 a side street football. Where attack met attack and nobody knew what defending meant. If only more games could be like this one.

Back under way.

More of the same please, lads.

Your weekly reminder that Lucas Torreira hails from Fray Bentos, Uruguay.

Tasty.
