Milan told to reject PSG bids for Silva
The highly-rated Brazilian defender has been strongly linked with a move to the Qatari-back Ligue 1 side the past week.
Speculation has been mounting that the French outfit are preparing to offer in excess of £40 million for the Selecao star.
However, with the 27-year-old believed to be in Paris waiting to undergo a medical, it now appears the Rossoneri want to keep hold of Silva.
"Berlusconi intends to resist all offers from PSG for Thiago Silva," Galliani told Sky Italia.
PSG sporting director Leonardo added: "There is no agreement.
"Many details have not been defined but this is normal considering the type of deal we are talking about.
"We will wait and see but I don't think the negotiations will take very long."
Thiago Silva has also been the subject of speculation regarding a part-exchange deal involving Barcelona midfielder Thiago Alcantara.
