Fenerbahce midfielder Matteo Guendouzi has been handed a four-match European ban—with two matches suspended—and fined 50,000 euros (£43,000) due to his involvement in a brawl following their Champions League play-off victory against Lyon. His teammate, English striker Mason Greenwood, received a one-match suspended ban and a 30,000 euros (£26,000) fine for similar conduct.

The incident occurred after Fenerbahce's win, which secured their place in the league stage with a 3-2 aggregate victory. Lyon goalkeeping coach Antonio Ferreira also faced consequences, receiving a five-match ban, two of which are suspended, for what UEFA described as a "serious assault" during the post-match clashes.

Guendouzi's punishment stemmed from his actions, which included:

• Insulting others present at the match
• Provoking spectators
• Violating basic conduct rules

Greenwood was penalized for "violating the basic rules of decent conduct" as well. Both clubs, Fenerbahce and Lyon, were also fined 50,000 euros for their teams' conduct.

During the match, Guendouzi faced repeated boos from Lyon supporters and appeared to taunt them after the victory. Following the final whistle, he was seen shouting "Allez l'OM" towards a pitchside camera, referencing his former club Marseille. A confrontation ensued as he left the field, leading to a melee in the tunnel involving players and security personnel.

In a post-match interview, Guendouzi expressed feeling "disrespected" by the taunts from Lyon fans, stating, "When you have 60,000 people insulting your family, your mother, your children, even before the game... I find that disappointing." He emphasized the need for officials to intervene in such situations.
