A number of Olympique Lyonnais players could face sanctions for joining in on derogatory chants about Saint-Etienne after their 1-0 Coupe de France final victory over Quevilly on Saturday.
The trophy was presented to the fans outside the team's hotel as thousands of supporters gathered. Several players including Cris, Maxime Gonalons, Alexandre Lacazette, Samuel Umititi and Jimmy Briand could face punishment for joining in on the chants that were offensive to their rival club.
According to Goal.com France, Saint-Etienne president Bernard Caiazo stated: "It is the duty of the players and officials to be respectful and not do something that can lead supporters to misbehave.
"It is quite undignified, I do not understand it. There are some big derbies, like Manchester City v Manchester United ... you cannot imagine that the players [from these clubs] start singing these type of songs.
"We, the Saint-Etienne officials, players and fans are shocked."
Caiazo added that he will appeal to the LFP in an attempt to resolve the matter. Meanwhile, Jeremie Janot, goalkeeper for Saint-Etienne, was also critical of the OL players' actions.
"If, by any chance, there is misbehaviour and violence at the next derby, they are largely responsible. They have stirred up hatred," Janot stated on Twitter.
"The Lyon players responsible for singing anti-Etienne chants must be punished! They have a duty to set an example. It is unacceptable," he added.
In a similar case from last year, Taye Taiwo was suspended for one game and fined €20,000 for participating in offensive chants whilst playing for Olympique Marseille.
