Aston Villa's Champions League quarter-final second leg against Paris St-Germain was marred by a system malfunction. The Europa League anthem was mistakenly played over the PA system as the players lined up at Villa Park on Tuesday. Club and Uefa sources revealed that the automated system for the anthem crashed and was overridden by another system. Several players reacted with confusion and amusement. Villa defender Ezri Konsa did a facepalm gesture, and midfielder Youri Tielemans struggled to contain their laughter. PSG's Fabian Ruiz and Ousmane Dembele exchanged puzzled glances. Fortunately, there are no Uefa sanctions for such incidents. Unai Emery's side had a heroic comeback but PSG progressed on aggregate.
