 Manager José Mourinho defended Begović's performance, attributing it to fatigue.His first competitive fixture was the 2015 FA Community Shield on 2 August at Wembley Stadium, in which he was unused in a 1–0 loss to rivals Arsenal.Six days later he came on as a substitute for Oscar when Courtois was sent off for conceding a penalty with a foul on Bafétimbi Gomis, who converted it for a 2–2 draw.
