FC Barcelona has officially submitted a complaint to UEFA concerning the refereeing during their UEFA Champions League quarter-final tie against Atletico Madrid. The club's statement highlights several contentious decisions made by referee Istvan Kovacs, particularly a missed penalty for a handball by Marc Pubill in the first leg and a red card issued to Eric Garcia in the second leg. Additionally, the non-awarding of a penalty for Dani Olmo has drawn criticism. This complaint follows an earlier submission after the first leg, which UEFA rejected as inadmissible. Barcelona contends that the accumulation of these refereeing errors has adversely affected the matches' outcomes, leading to both sporting and financial repercussions for the club. They have reiterated their call for improvements in refereeing standards and expressed a willingness to collaborate with UEFA to ensure fairer application of the Laws of the Game.
