Despite Villa's dominance last season, which included two wins over Arsenal that contributed to the Gunners losing the title, Villa failed to capitalize on several chances, with Ollie Watkins missing two clear opportunities.
Arsenal broke the deadlock in the 67th minute through Trossard, with Partey adding a second 10 minutes later. The victory ended Villa's recent stronghold over Arsenal and kept Arteta's side on track for a serious title challenge.
