The two clubs agreed a fee, believed to be between 10 and 15 million euros, earlier this month but the deal stalled this week when the French defender's medical showed up a tooth problem.

However, the 21-year-old's representative Roger Boli believes his client will be wearing Rossoneri colours next season.

"It is ongoing, but I'm pretty confident," Boli told L'Equipe.

"The hardest thing was that the two clubs reach an agreement on the transfer fee."
