The Rossoneri have reportedly made a 6m offer for defender Yanga-Mbiwa, but the French club rejected it out of hand, even though he only has a year left to run on his contract.
"They think they're really smart at Milan. They just sold a defender for 45m and would like to sign one equally as good for a pittance," slammed Nicollin on Canal+.
"If they were to come to me with an offer of 25-30m, then I might think about selling the lad, but from what I understand they want to spend no more than 5-6m.
"Let them focus on making their little movies. We don't care. If a suitable offer does not arrive, then Yanga-Mbiwa will stay."
