There's a long ball and a real scramble. Arsenal don't clear their lines and when Barnes gets the second chance he doesn't miss - just puts his laces through it. Burnley are back in it.

Ashley Barnes
Game on!
An absolute gift for Burnley as shocking defending by Arsenal allows the visitors to haul themselves back into this.
The Gunners have four or five chances to clear the ball before Ashley Barnes drills low and hard into the corner of the net.

Kolasinac pushes Long and though Long makes the most of it, you are not allowed to stop a player moving like that.
I think he is lucky to get away with that, it could easily have been given as a penalty.

Where's the Christmas love?
Kevin Friend is being made to work hard to earn his money.

A push on Kevin Long by Sead Kolasinac inside the Arsenal area but no penalty!

Is this going to end 11 v 11?

Jack Cork had the ball in the Arsenal box and 30 second later Kolasinac is breaking at the other end of the pitch.
Aubameyang in that position takes a touch to draw the defender in, another to get away and the third is a lethal finish.
Joe Hart has got no chance. Near post but it's so fast. That combination Lacazette and Aubameyang, they'll get a lot of goals this season.
Pierre-Emerick Aubameyang
Smashing finish!
Burnley are caught cold after an attack goes wrong and Arsenal punish them on the counter with a terrific finish from Pierre-Emerick Aubameyang who lashes past Joe Hart.
It's a rocket shot from the Gabon striker but where was Burnley's defending?

Nasty collision between Bernd Leno and Chris Wood.
Wood doesn't see the Arsenal keeper come rushing out of his area to make a headed clearance. The Burnley striker catches his opponent and it's a booking for Wood.

Arsenal have done enough. It has not been scintillating but a very good goal. Burnley are well in the game. The team talk from Sean Dyche will be encouraging.
But Arsenal have quality on the pitch, you may fear they'll get more chances.

Ben Mee got the ball in loads of space but had a trampoline touch. The ball gets to Lacazette who does great, but a brilliant brilliant tackle from Kevin Long. Timing was everything otherwise it was a penalty
