Barcelona manager Hansi Flick expressed his frustration over VAR's failure to intervene during a crucial moment in their Champions League quarter-final against Atletico Madrid, where a potential penalty against Marc Pubill was not reviewed. Flick stated, 'You can make a mistake once, but not twice,' highlighting the club's decision to file a complaint to UEFA regarding the officiating. He acknowledged that while Barcelona did not play their best game, the lack of VAR intervention was 'decisive' in the match's outcome. Regarding comments made by Real Madrid manager Alvaro Arbeloa about officiating bias, Flick chose to focus on his own team, stating, 'I don’t waste my energy' on external opinions. He stressed the importance of concentrating on their performance and winning games, rather than getting caught up in the surrounding noise.
