The UEFA is planning to punish both clubs for the actions of their supporters, who set off fireworks, caused incidents on the tribunes and threw objects at Guendouzi. The European football governing body will also investigate the actions of players and staff members. Guendouzi's past with Olympique Marseille, the arch-rivals of Lyon, is seen as a contributing factor to the unrest. The fans of Lyon threw objects at Guendouzi, causing the unrest to escalate. The UEFA's investigation will look into the incidents on the tribunes and the actions of players and staff members, including Guendouzi, who was at the centre of the unrest. The disciplinary committee will consider possible suspensions for players and staff members involved.
