Arsenal are coming out of a defensive injury crisis that threatened to be a problem in the first chapter of the season, but Mikel Arteta now faces a new headache at the top end of the pitch.
William Saliba and Piero Hincapié are the only defenders now sidelined, with an expectation that the latter could be back by the weekend. Saliba is a long-term absentee left over from the summer, aggravating a back complaint during the 2026 World Cup, but also appears to be ahead of schedule and could be fully recovered some time next month.
