Rod Fanni's agent claims Nice are prepared to sell the French defender, with Celtic among the clubs interested.
Fanni wants a move away from Nice
The 25-year-old would prefer to join a club involved in Champions League, which puts Celtic in a strong position.
Fanni's agent Dominique Six told the News of the World: "We have had interest in Rod from Monaco, Celtic, Genoa and St Etienne.
"Celtic have looked at him many times. He knows about that and would have no problems about going to Celtic."
Fanni began his career with hometown club Martigues before playing for Lens and Chateauroux then joining Nice in 2005.
"I got calls a few times last season from the Nice sporting director, Roger Ricort, saying that Celtic had been at a Nice match to see Rod play," added Six.
"It is a very big club that is always competing at the top level in Europe.
"I was the agent when Momo Sylla joined Celtic, so I know it is a good club to deal with.
"I understand why there is interest in Rod. It's expected he will be in the French national team in the coming season.
"It is certain he will leave Nice this summer. I met the club president, Maurice Cohen, on Friday and we agreed this.
"The only thing that will have to be decided is the price, since Rod is under contract until 2010."
Monaco have already had a bid of £2m rejected for the player, according to reports.
