Football Club Barcelona (FCB) has officially reported Paris Saint-Germain (PSG) fans to UEFA following a match at the Parc des Princes. The complaint centers on a highly provocative banner, or tifo, displayed by PSG supporters, which depicted a masked figure in a PSG shirt using a chainsaw on the Barcelona crest, referencing 'The Texas Chain Saw Massacre'. Barcelona also noted offensive songs sung by the fans during the game. French media reports indicate that PSG had pre-approved the tifo, though the club has not commented publicly. UEFA disciplinary regulations, specifically Article 16 (2e), address the use of provocative messages unfit for sports events, with a standard first-time sanction being a 10,000 euro fine.
