UEFA Opens Disciplinary Proceedings After Chaos in Lyon
European football’s governing body has officially opened disciplinary proceedings against Fenerbahçe, alongside club players Mattéo Guendouzi and Mason Greenwood.
What began as a tense battle on the pitch quickly spilled over into fiery post-match celebrations and confrontations, drawing the immediate attention of UEFA officials. In that high-stakes fixture in Lyon, Fenerbahçe secured a 2-1 victory, sealing an elimination that cut short Olympique Lyonnais’s European campaign.
Flashpoint and Provocation on the Pitch
Statements released by the Turkish club confirm that European soccer authorities formally launched the dossier earlier in the week. The proceedings target both the Istanbul-based organization and two of its most prominent summer arrivals: French midfielder Mattéo Guendouzi and English forward Mason Greenwood.
The controversy centered around post-match antics directed toward the home crowd. Guendouzi, a former Olympique de Marseille player who was targeted by sections of the Lyon support from the pre-match warm-ups onward, reacted visibly to the hostile environment.
French sports desks confirmed that the midfielder made an offensive gesture—specifically a middle finger—toward the Lyon supporters, touching off a broader melee on the pitch as tempers flared at the final whistle.
Guendouzi Defends Actions Amid Hostile Crowd
In the immediate aftermath of the fixture, Guendouzi defended his actions publicly. He insisted he had done nothing wrong given the provocation he faced from the stands.

According to comments reported by regional and national French media, the midfielder stated that supporters had insulted his mother, his family, and his children.
Greenwood, who also previously played for Marseille, joined his teammate in taunting the Lyon supporters as the Turkish side celebrated their aggregate progress.
Fenerbahçe Prepares Legal Defense
In response to the unfolding UEFA investigation, Fenerbahçe issued a formal statement outlining their legal and administrative stance. The club stated that it will present all necessary arguments before the competent bodies to protect the rights and interests of both the team and its players.
No timeline for a final ruling has been officially announced by governing authorities.
