24' Aubameyang has just made his way to the side of the pitch to get some treatment as he was caught on his mouth and the referee spotted the cut was bleeding. He's quickly patched up though and sent back out onto the field.
22' BLOCK! It's better from Chelsea now and Pulisic makes a driving run down the right and Azpilicueta slides it into him. He pulls it back from the byline for Mount in the middle, who hits the shot first time, but Mari is there to make an important block.
20' Chelsea are trying to get themselves back into the game, but their passing is sloppy whenever they move out of their own half. Gilmour switches play out to Chilwell, who is in space on the left, but his first touch is poor and it bounces straight out.
18' Chelsea just can't deal with Arsenal's high press at the moment and they're almost caught out again as Odegaard wins it back in midfield. He spins and tries to lay it off to Saka, but Zouma is there to intercept it.
15' The visitors are still moving the ball upfield quickly and Holding finds space down the right again. He spots Smith Rowe making a late run into the box from the left and tries to pick him out with a cross, but James is there to head it back to Kepa.
13' Arsenal are moving the ball upfield quickly but Partey's throughball into Saka is intercepted. The visitors keep hold of it through Odegaard, who switches play out to Holding on the right, but his cross is overhit and Aubameyang can't get close to it.
11' MISS! None of the Arsenal defenders spot Havertz's run off the back of them and he's teed up by Jorginho. He drives into the box and lifts his shot over Leno, who rushes off his line, but it's too high and sails over the crossbar.
10' Chelsea are unbeaten in their last eight home Premier League matches against Arsenal (W6 D2), since losing 5-3 at Stamford Bridge in October 2011 under Andre Villas-Boas.
8' Arsenal go long again, this time with Gabriel playing the long ball over the top to Aubameyang. The forward brings it down well before turning away from Azpilicueta to get into the box, but the offside flag is up against him.
6' Chilwell steps away from Holding and slots the ball into Pulisic ahead of him on the left. There are no Chelsea players in the box, so he pulls it back for Mount, who hits an early low shot on goal, but it's straight at Leno.
4' It's Chelsea's turn to keep possession now and they're keeping the visitors penned back in their own half. It's patient play from them though as they try to open up some space in behind Arsenal.
2' Arsenal are seeing a lot of the ball in the opening couple of minutes here and have already played a couple of long balls into Chelsea's box. Aubameyang has chased them down, but they've been too far ahead of the forward.
1' Odegaard gets the game underway for Arsenal!
