Shortly after the final whistle, fights broke out on the square at Groupama Stadium, where Lyon fans attacked a small group of Besiktas supporters. The incentives started when Gedson Fernandes opened the score, when this block of two dozen people who were invited by the Istanbul club cheered on the right side of the Turkish bench and looked at the scorer, arms in the air and in the middle of several security guards. The scenes of celebration were repeated at the end of the game, when they celebrated the victory with the players and staff, and the two local corners responded with whistles.
A physical confrontation then occurred, at exit H, where CRS quickly intervened, using tear gas, before forming a cordon in the middle of the corridor. Garbage cans were thrown on the ground and the interior doors of the stadium were locked as a precaution for several minutes, until the rest of the group, some of them with Turkish flags, were evacuated around 11:25 p.m., not without tension. Which somewhat spoils the results of a controlled night so far.
