Ollie Watkins scored two goals as Aston Villa maintained their 100 per cent away record with a 3-0 success at Arsenal.
The visitors started brightly and John McGinn had a first-minute strike ruled out by referee Martin Atkinson following a review.
But Villa went ahead on 25 minutes. Bukayo Saka tried to clear Matt Targett’s cross and, under pressure from Trezeguet, steered the ball into his own net at the back post.
And they got a deserved second on 72 minutes with a close-range header by Watkins from Ross Barkley’s superb delivery.
Watkins made the points safe only three minutes later, this time providing a crisp first-time finish following a driving run by Jack Grealish.
Villa’s win, their third on the road this campaign without conceding a goal, moves them up to sixth spot on 15 points, three clear of Arsenal in 11th.
