Nice coach Patrick Vieira is angry over reports linking him with Lyon.
Vieira has been mentioned as a candidate to succeed Bruno Genesio, who is off contract at OL in June.
But the Arsenal Invincible said: "I'm always clear and I cannot understand all that.
"It is unfounded, unhealthy and inappropriate for the club, which is going through difficult times in its restructuring."
Nice powerbrokers Jean-Pierre Riviere and Julien Fournier resigned last month.
