UEFA opened a disciplinary proceeding against players Matteo Guendouzi and Mason Greenwood, both from Marseille, after the incidents that occurred during the Champions League play-off tie against Lyon. Both players were targeted by the European football regulatory body due to their behavior during the tie.
Fenerbahçe is also the subject of a separate disciplinary proceeding. The Turkish club faced Lyon in the other semi-final of the play-off for qualification to the Champions League group stage, and the club's players will also have to answer to UEFA.
What motivated the disciplinary proceedings were the provocative celebrations of both players at the end of the play-off matches. The celebrations were considered excessive and provocative by the European sports authorities.
UEFA did not specify which articles of the disciplinary regulations were allegedly violated, but confirmed the official opening of proceedings against the players and the Turkish club.
