Arsenal maintained their perfect start to the season with a 2-0 win away at Sunderland, though the scoreline flattered a side that Mikel Arteta admitted faced its toughest test of the campaign so far. David Raya's crucial second-half penalty save from Enzo Le Fée proved the turning point, with Bruno Guimarães scoring against his former club Newcastle-supporting rivals two minutes later before Bukayo Saka added a stoppage-time penalty after Reinildo was sent off for fouling him.

The victory was Arsenal's sixth in six games across all competitions this season, including the Community Shield, but Sunderland's disciplined, physical display gave Régis Le Bris cause for optimism despite the defeat. Substitutes Guimarães and Jurriën Timber, introduced at half-time for Myles Lewis-Skelly and the injured Ben White, changed the game's complexion, while Raya's brilliant save kept Arsenal level before their late double breakthrough sealed the points.
