UEFA opens Mason Greenwood probe after Lyon celebrations

UEFA opens Mason Greenwood probe after Lyon celebrations

UEFA has opened disciplinary proceedings against Mason Greenwood and Fenerbahce team-mate Matteo Guendouzi after alleged provocative celebrations following their Champions League play-off win over Lyon. The Turkish club confirmed the probe in a public statement and says it will defend the players and the club before UEFA.

The move puts Greenwood under the spotlight just weeks into his Fenerbahce career and raises the prospect of sanctions that could affect the club's early Champions League fixtures, including a meeting with Roma.

Key Takeaways

What triggered the UEFA Mason Greenwood investigation?

According to reporting from the Daily Express, UEFA announced disciplinary proceedings against Greenwood and Guendouzi after Fenerbahce's Champions League play-off second leg against Lyon.

The former Manchester United forward joined the Turkish Super Lig club in the summer and helped Fenerbahce reach the main draw of the Champions League. That on-pitch progress was overshadowed by scenes after the final whistle.

Several members of the Lyon crowd attempted to gain access to the pitch while Fenerbahce players celebrated. Greenwood and Guendouzi were spotted allegedly provoking the home fans. Their previous links to Marseille, Lyon's fierce rivals, added extra heat to the reaction.

Greenwood was caught on camera appearing to grab his groin area toward Lyon supporters. Guendouzi was seen appearing to stick his middle finger up at the crowd. Those images have drawn UEFA's attention.

ESPN reported that Guendouzi was at the centre of a mass brawl after Fenerbahce's 2-1 win in France, with clashes on the pitch and in the tunnel involving players and staff from both sides. Lyon said the closing stages were marked by high tensions after what it called a provocative celebration by Guendouzi in front of home supporters.

What did Fenerbahce say about the Mason Greenwood case?

Fenerbahce confirmed the UEFA action in an official release. The club said disciplinary proceedings had been opened against Guendouzi and Greenwood, as well as against the club itself, following the Champions League play-off second leg.

In the statement, Fenerbahce said it would present the necessary defences before the relevant UEFA bodies to protect the rights and interests of the players and the club. It added that all required information, documents, and defence materials would be submitted, and that developments were being closely monitored.

That public response underlines how seriously the club is treating the matter, especially with proceedings opened against both the players and Fenerbahce as a club.

Could Mason Greenwood miss Fenerbahce vs Roma?

RomaPress reported that Greenwood and Guendouzi are at risk of being disqualified for Fenerbahce's Champions League meeting with Roma. Roma are due to open their Champions League campaign away to Fenerbahce on Thursday, September 10.

The outlet noted that a brawl broke out after Fenerbahce's win over Paulo Fonseca's Lyon side, describing a chaotic mix of mockery, physical confrontation, and verbal abuse, with Guendouzi among those involved. UEFA's decision to open proceedings is why both men now face uncertainty over availability.

No final punishment has been announced in the available reporting. Until UEFA completes the process, any ban or suspension remains a risk rather than a confirmed outcome. Fenerbahce's defence submissions will be central to how the case develops.

Why does Guendouzi's Lyon history matter here?

Context from ESPN helps explain why the scenes escalated so quickly. Guendouzi played for Marseille between 2021 and 2024 and was repeatedly booed throughout the Groupama Stadium match. Tempers flared to the point that teammates had to hold him back.

After the brawl, Guendouzi was captured shouting "Allez l'OM" toward a pitchside camera, referencing Marseille. He later said he felt disrespected by the home crowd and argued that banter "goes both ways," claiming supporters insulted his family for the entire match.

Asked about the "Jul" hand gesture associated with Marseille pride, Guendouzi said everyone knows he supports OM and framed the gesture as banter rather than malice. Lyon, meanwhile, publicly criticised what it called a provocative celebration in front of its fans.

Greenwood's alleged gesture toward the crowd placed him in the same disciplinary frame as Guendouzi, even though much of the post-match narrative centred on the Marseille-Lyon rivalry.

What is next for Fenerbahce in the Champions League?

Despite the controversy, Fenerbahce left France with a 3-2 aggregate win and a return to the Champions League league phase. Coach Ismail Kartal called the qualification incredibly fulfilling and a source of pride for Turkish football and the club's fans.

The Express reported that Fenerbahce's league-phase slate includes a home meeting with Liverpool in early October, an away trip to Atletico Madrid, a visit to Aston Villa, and further matches against Slavia Prague, Shakhtar Donetsk, LASK Linz, Roma, and Villarreal.

That fixture list raises the stakes around any possible suspension. A temporary absence for Greenwood or Guendouzi would not only reshape squad planning for the Roma game but could also ripple into other high-profile European nights.

For now, the verified facts are clear: UEFA has opened proceedings, Fenerbahce has confirmed them publicly, and both Greenwood and Guendouzi face potential consequences while the club prepares its defence. Further clarity will depend on UEFA's next steps and any sanctions that follow.
