Arsenal defeated Brentford by a single goal to claim all three points away from home.
The winning goal came from Kai Havertz. The German was subbed on in the 79th minute of the second half and found the back of the net 10 mins later.
Despite the scoreline favouring Arsenal, it was a chaotic game with the Gunners needing to make two goal line clearances in each half. The first from an Aaron Ramsdale mistake.
