Emile Smith Rowe and Bukayo Saka scored second-half goals as Arsenal beat Brentford 2-1 and moved within one point of the top four.
The Gunners started quickly at Emirates Stadium, with Saka testing David Raya shortly before Alexandre Lacazette tapped in a Granit Xhaka cross, only for the goal to be ruled out for offside.
Smith Rowe eventually broke the deadlock with Arsenal's 17th shot of the match, cutting in from the left and finding the bottom-right corner on 48 minutes.
Arsenal's second goal came 11 minutes from time as Saka finished well off the far post.
Christian Norgaard got a goal back for Brentford in second-half stoppage time but it was too late to prevent Arsenal recording back-to-back victories.
The Gunners remain sixth but have at least two matches in hand on all of the teams above them.
Brentford stay 14th with 24 points, six points clear of the bottom three.
