Following Szczęsny's form after playing consecutive Premier League matches, Arsène Wenger confirmed that he would remain Arsenal's first choice goalkeeper, stating, "he's done nothing for me to take him out." On 16 February, Szczęsny made his UEFA Champions League debut against Barcelona at the Emirates Stadium, making saves in a 2–1 victory. On 27 February, Szczęsny let in a last-minute Birmingham City winner in the League Cup Final; a header from Nikola Žigić caused confusion between Szczęsny and defender Laurent Koscielny where the latter pulled out of a clearance at the last minute causing the former to lose control of the ball, which rolled right into the path of Birmingham forward Obafemi Martins, who converted from close range.
