Arsenal 3-1 Burnley
This is a hard defeat to stomach for Burnley who were much better than the scoreline suggests.
Sean Dyche is not hanging about. A quick shake of Unai Emery's hand and he's off down the tunnel.
The Clarets boss is not happy!
Arsenal 3-1 Burnley
Christmas cheer for Arsenal who move level on points with Chelsea - for at least two hours.

Mesut Ozil: Discuss!
Arsenal 3-1 Burnley
Lee Dixon
Former Arsenal and England defender on BBC Radio 5 live
There was going to be gaps and space as Burnley pushed forward for an equaliser and Arsenal took advantage.
Iwobi scored but Ozil does all the work, he picks the ball up in midfield an drives and drives.
That takes the pressure right off.
Arsenal 3-1 Burnley
Six of the 20 Premier League goals Arsenal have scored against Burnley have been scored in the 90th minute.
Alex Iwobi
Game over!
More magic from the boots of Mesut Ozil who goes past one challenge and another before his deflected pass falls to substitute Alex Iwobi to fire past Joe Hart.
Was Iwobi offside? It's tight but Kevin Friend allows the celebrations to continue.

Another wave of frustration sweeps the Emirates as no red and white shirt is able to connect with Sead Kolasinac's fizzing ball across the six-yard area.

Bel: 2-2 written all over this.
Coley: There is no such thing as a 'comfortable 2-0 lead'!! Never has been, never will be!
Message received, Coley. I've been well and truly told...
Arsenal 2-1 Burnley
This has been a hard-working performance from Sean Dyche's men. They've given their all in the second-half. Whatever the outcome, this will give them some encouragement before the Boxing Day home clash with Everton.
Arsenal 2-1 Burnley
Arsenal haven't had a shot on target since Aubameyang's second goal.
Eight minutes plus added time remaining. Still time for some late drama.
Arsenal 2-1 Burnley
Alexandre Lacazette is not a happy bunny.
He is very animated as he is replaced by Alex Iwobi.
The camera cuts to the Arsenal bench where Lacazette looks furious.

Ashley Barnes and Chris Wood will not be getting sent off - both are hooked before they can pick up another booking.
Sam Vokes and Matej Vydra are on.
Arsenal 2-1 Burnley
Still plenty of time for a red card. There's no love lost between these two teams. It's been a bruising affair.
Arsenal 2-1 Burnley
Chris Wood gets away with one as he trips Matteo Guendouzi.
The Burnley forward is already on a yellow and Kevin Friend decides to keep his cards in his pocket.
That was borderline.
Arsenal 2-1 Burnley
Another hush inside the Emirates as Burnley are presented with another chance - Jack Cork bending the ball wide from an angle.
This is going to be a nervy finale!
Arsenal 2-1 Burnley
Ashley Barnes has the ball at his feet just outside the Arsenal six-yard area but the flag is up for a foul.
Barnes is livid!

Gregory: Barnes-storming goal! Still time!
Dom: Great finish, but Barnes should not still be on the pitch. Burnley very lucky.
Kyle: That goal was like a goalmouth scramble you would see in a school playground - it wasn't Premier League defending. Awful defending from Arsenal and Burnley are right back in this game. The home side cannot defend.
Arsenal 2-1 Burnley
Arsenal are rattled.
From a comfortable 2-0 lead, they now look nervous and are making mistakes.
