Barcelona have lodged a formal complaint with UEFA following their 2-0 defeat against Atletico Madrid in the first leg of the Champions League quarter-finals, disputing the refereeing decisions during the match held on Tuesday at Camp Nou.

The complaint centers on a key incident early in the second half when Barcelona appealed for a penalty after Atletico goalkeeper Juan Musso appeared to put the ball back into play from a goal kick. Shortly thereafter, Atletico defender Marc Pubill handled the ball inside the six-yard box before regaining possession. Referee Istvan Kovacs allowed play to continue, and the Video Assistant Referee (VAR) team did not review the decision, prompting sharp protests from the Barcelona coaching staff and players.

In an official statement, Barcelona confirmed that their legal department submitted a formal protest to UEFA focusing on the sequence in the 54th minute. The club argued that the opponent’s handling of the ball in the penalty area should have resulted in a penalty, which they say was a clear refereeing error further compounded by VAR’s failure to intervene. Barcelona has requested UEFA open an investigation, grant access to refereeing communications, and formally acknowledge any mistakes made, along with appropriate corrective measures.

The interpretation of such incidents has varied in recent UEFA competitions. For instance, in the 2024 quarter-finals, a similar situation involving Bayern Munich and Arsenal did not result in a penalty despite an apparent handball following a restart. Conversely, in another 2024 match, VAR sanctioned a penalty after a comparable sequence between Club Brugge and Aston Villa. This inconsistency has contributed to the controversy surrounding the Barcelona case.

Barcelona manager Hansi Flick expressed his frustration after the game, criticizing both the non-awarded penalty and the team's early reduction to ten men following Pau Cubarsi’s red card just before halftime. Cubarsi was sent off in the 44th minute for fouling Giuliano Simeone as the last defender, leading to a free kick from which Julian Alvarez opened the scoring for Atletico. Flick questioned the legitimacy of the dismissal and lamented the perceived lack of VAR involvement, stating he could not understand why technology was not used to address these critical decisions.

Atletico coach Diego Simeone, meanwhile, defended the referee’s judgment, emphasizing that the official’s determination matched what the players involved perceived during play. Simeone described the situation as one of common sense and dismissed calls for further scrutiny.

The second goal for Atletico came early in the second half from Alexander Sorloth, effectively sealing their advantage heading into the second leg. Barcelona’s protest to UEFA highlights ongoing debates about VAR’s role and the consistency of officiating in high-stakes Champions League matches.
