Hector Bellerin has hinted Arsenal's players are still adjusting to manager Unai Emery's system after victory over West Ham.

The Gunners broke up the game late on to win 3-1.

Bellerin said: "At the end of the day it's football, right, and that's what we've always been playing and there's always a few adjustments here and there that we need to make in order to play the style that the coach wants to play, but of course we've been playing with each other for a long time so even though the system changes, at the end of the day we're the same players so we still understand each other and that helps.

"It's all about the work of the team and we've been working really hard this week and we knew what we had to do in order to score goals and that's what we all did together."
