On 1 January 2015, Szczęsny made errors leading to both goals in Arsenal's 2–0 defeat at Southampton. He was later fined £20,000 by the club for smoking in the changing room showers after the match. He was dropped to the bench for the rest of the Premier League season, with David Ospina replacing him in goal. Szczęsny was selected to start in the 2015 FA Cup Final, keeping a clean sheet in a 4–0 victory over Aston Villa at Wembley Stadium.
