Barcelona file fresh UEFA complaint over Champions League refs - ESPN
Barcelona has officially filed a complaint with UEFA concerning the performance of referees in their Champions League games, aiming to address perceived inconsistencies and biases.

Barcelona has lodged a second complaint with UEFA regarding the refereeing standards during their Champions League quarterfinal exit against Atlético Madrid. The Spanish champions are adamant that the officiating errors throughout both legs of the tie have resulted in "significant sporting and financial harm" to the club.
Details of the Complaint
In a statement released on Thursday, Barcelona expressed their concerns over the refereeing performance in the matches against Atlético. They highlighted that several decisions made did not adhere to the Laws of the Game, which they believe stemmed from incorrect application of the regulations and insufficient intervention from the VAR system in crucial situations.
The club emphasized that the accumulation of these errors directly influenced the matches' outcomes, leading to their elimination from the tournament. Barcelona reiterated their previous requests to UEFA and expressed a willingness to collaborate with the organization to enhance the refereeing system for a more rigorous and fair application of the rules.
Previous Complaints
This is not the first time Barcelona has raised concerns regarding officiating in this tie. They had previously filed a complaint after the first leg, claiming that a penalty and a red card should have been issued when defender Marc Pubill, already on a booking, handled the ball after goalkeeper Juan Musso appeared to restart play.
Despite their strong efforts, Barcelona's Champions League campaign came to an end as Atlético Madrid advanced with a 3-2 aggregate victory, setting up a semifinal clash with Premier League side Arsenal.
