Arsenal boss Unai Emery was pleased to see a 4-4-2 formation work for victory at Fulham.

Alexandre Lacazette and Pierre-Emerick Aubameyang both struck twice for the 5-1 win.

Emery said, "It is one process, to know better after training, after every match, after every decision, how we are better on the pitch, between the players, in our tactical system and impose our timing on the pitch in possession with the ball.

"Today is the first we played more clearly 4-4-2 with Danny and Lacazette first, and then Laca with Auba. Then Aaron is like a 10 player, but he can play near the attack and he can score or do an assist like today."
