Full-time: Arsenal 2-2 Chelsea
Chelsea denied a winner! Alvaro Morata misses another clear cut chance, breaking between the Arsenal defence and moving one-on-one with Courtois. His attempt on goal is awful, dinking it straight into Cech's chest but the ball bounces back out to Zappacosta who hammers the rebound on goal. It looks destined for the top corner but it comes back off the underside of the bar!
Bellerin equalises! A cross is only partially cleared by Chelsea and the loose ball bounces to the Spaniard inside the box, who connects with a flawless half-volley, guiding it past Christensen and past Courtois in goal. Wonderful equaliser.
Goal! Arsenal 2-2 Chelsea (Hector Bellerin, 90+1)
Bellerin stays onside as he is fed down the right channel and lifts a ball across the face of goal but no one can get on the end of it!
Sanchez sees his effort from inside the six yard box blocked and Wilshere's attempt to cross the ball over to the back post is momentarily cleared. Arsenal come again though...
Four minutes of time added on at the Emirates.
Alonso has done it again, Chelsea are heading towards three points and second place as things stand.
Theo Walcott is on for Chambers before the corner comes in but Chelsea deal with it. Mustafi connects with a superb volley as the ball comes back in but Cahill makes a terrific block to keep it away from goal.
Mustafi hoofs a ball down the inside right for Welbeck to run onto in acres of space. Ozil and Sanchez are waiting in the middle but the former Manchester United forward can#'t find them, winning a corner.
Arsenal have five minutes to rescue something here.
Chelsea have the lead! Maitland-Niles has been superb tonight but on this occasion he loses out to Zappacosta, with the Italian turning inside the young full-back before pinging an inviting ball across goal from the right. There are three Arsenal players inside the six yard box but Alonso makes a terrific run in between the lot of him to drill home from close range.

Here's another Chelsea change and it is Hazard coming off. The Belgian doesn't look like he is carrying a knock as Willian comes onto replace him.
Bellerin does superbly well down the right to burst past his man and lift a cross into Welbeck but Zappacosta does well to usher the ball away.
And a change for Arsenal; Lacazette comes off to be replaced by Danny Welbeck.
Hazard frees Morata with an absurd piece of skill, allowing the Spaniard to race down the inside left channel. Hazard has raced into the box for the return but Cech gets to it first.
15 minutes left in this pulsating clash in north London.
But he was brought crashing back down to earth moments later when Chelsea were awarded the penalty.
Take off for Jack Wilshere....
Another change for Chelsea: Danny Drinkwater is on for Fabregas.
Arsenal are caught out at the back again and Fabregas can pass a ball through the middle for Morata to race onto. Mustafi is doing his best to keep up with him and manages to put the striker under just enough pressure to force him to fire wide.
Hazard steps up... and slots it past Cech! For the second time in four days, Arsenal lose a lead to a penalty - this one looked a bit soft, too. Arsene Wenger will be cheery post-match...
