FC Barcelona has escalated its concerns over officiating, filing a second formal complaint with UEFA regarding the refereeing in their dramatic Champions League quarter-final exit to Atletico Madrid.

The club's frustration stems from a series of contentious decisions across both legs of the high-stakes tie. The first leg featured a particularly controversial moment where a potential penalty for a handball by Marc Pubill was not awarded by referee Istvan Kovacs.

Controversy followed into the second leg, with Barcelona pointing to Eric Garcia's red card and a denied penalty appeal for Dani Olmo as key grievances that altered the match's dynamics.

This marks Barcelona's second official approach to UEFA, after an initial complaint following the first leg was dismissed. In a detailed statement, the club argued that an "accumulation of errors" in applying the laws of the game, including insufficient VAR intervention, directly impacted the tie's outcome, causing significant sporting and economic damage.

Beyond seeking redress, Barcelona's complaint concludes with an offer to collaborate with UEFA, aiming to improve the refereeing system for greater fairness and transparency in future competitions—a move that underscores the intense pressure and fine margins at football's elite level.
