Sports Mole brings you live commentary of the Premier League clash between Chelsea and Arsenal.
STATISTICS! Arsenal shaded the first-half possession with 51%, while the Gunners had 10 attempts in the first period, although just two of those were on target. Chelsea, meanwhile, hit the target with two of their four attempts. Both teams have missed some excellent chances to score here.
BENCH WATCH! Arsenal are without Ozil this afternoon through injury, but Olivier Giroud, Theo Walcott and Alexis Sanchez are all on a dangerous Gunners bench. Chelsea, meanwhile, have the likes of Bakayoko, Batshuayi, Hazard and Zappacosta in reserve. Plenty of talent on both benches!
So there we have it. The referee brings the first period to a close with the two teams level at 0-0. Chelsea made the brighter start to proceedings, but Arsenal ended the first 45 minutes extremely well, and really should have made the breakthrough. A very even first half of action in London!
Monreal drills the ball back to his own goalkeeper after beating Morata for pace, and Cech does well to control on his chest. Almost a very embarrassing moment for the visitors! Arsenal then break down the other end, and Luiz has to clear ahead of the waiting Lacazette at the near post.
Chelsea need to regroup at the interval. Pedro and Willian have been invisible for the last 20 minutes or so, and Conte will surely be considering introducing Hazard at the interval.
CHANCES! Oh my word! Wonderful chance for Arsenal as Ramsey dances into the Chelsea box before poking the ball towards the far corner, it hits the post, and Lacazette somehow smashes the rebound over the crossbar. It is a quite incredible miss from the striker!
Chelsea were very impressive in the early stages of this match, but Arsenal have been comfortable for some time now, with the Gunners enjoying lots of possession in Chelsea's half of the field. Just a reminder that Alexis Sanchez is on the Arsenal bench this afternoon. We will surely see him at some point.
Morata does well to clear an Iwobi free kick, which had been threatening to find the head of Welbeck inside the Chelsea box. Arsenal are currently enjoying a really good spell here.
Pedro is a touch fortunate to escape a yellow card for a late challenge on Xhaka, with the referee deciding to have a word with the Chelsea attacker rather than issue a booking. Not too much to report in terms of chances in the last few minutes as both defences stay on top in London.
Chelsea's pace has slowed down over the last five minutes or so, and credit must go to Arsenal after a difficult start for the Gunners. It is a very even game with 34 minutes on the clock here.
Fabregas looks to find Luiz with a super cross towards the far post, but the centre-back cannot grow tall enough, and Arsenal manage to clear their lines once again. Still goalless in London.
'Chelsea! Chelsea! Chelsea!' rings out around the stadium as the home side's supporters look to rally a team that is currently allowing Arsenal a lot of possession in potentially dangerous areas. Welbeck and Iwobi are starting to find space in wide positions, while Lacazette has been a threat.
Just a reminder that a win for Chelsea would take them into second, while Arsenal would jump to fifth with all three points this afternoon. Both sides have had a couple of good opportunities to make the breakthrough at Stamford Bridge, but the score remains goalless with 26 minutes on the clock.
You do get the feeling that the first goal - if there indeed is one - could be vital this afternoon. Arsenal have certainly improved after a difficult start to the match. It is a very enjoyable game.
Morata heads over the Arsenal crossbar after another super cross from Moses. End-to-end football in the last few minutes, but the score remains goalless at Stamford Bridge.
SAVE! Wonderful chance for Chelsea to take the lead as Pedro breaks into a one-on-one situation following a super Fabregas pass, but the Spaniard cannot beat Cech!
SAVE! Courtois has to get down to keep out a strike from Kolasinac as Arsenal continue to threaten. The Gunners have had three opportunities in the last few minutes at Stamford Bridge.
CHANCE! Brilliant chance for Arsenal as Bellerin finds the head of Welbeck with a super cross from the right, but the England forward can only send his effort over the crossbar!
Arsenal come under more pressure as Moses delivers a dangerous cross into the away side's box, but Koscielny manages to head clear, and eventually Willian runs the ball out of play. There is no question that Chelsea are carrying the bigger threat in the final third of the field here.
So, still goalless with 15 minutes on the clock. Chelsea have had the better moments, but Arsenal have shown little bits and pieces in the final third of the field. Lacazette's touch and link play has been impressive in the early stages, although Courtois has been unmoved between the home side's sticks.
Bit of possession for Chelsea as they pass and probe in a central position, but Morata cannot collect a through ball from Fabregas, allowing Arsenal to build from the back through Cech.
Zappacosta has been sent to warm up as Moses hobbles around. Chelsea might well be forced into an early change. Lacazette, on the other hand, is now moving freely in Arsenal's final third.
