The Brazil defender is also being linked with Barcelona.
Galliani said: "I can assure everyone that Thiago Silva is priceless. PSG and my friend Ancelotti asked repeatedly for him, but he loves Milan just as his President Silvio Berlusconi loves him.
“I don’t understand how some can criticise the President when he has put so much into the club during a moment of world financial crisis. We should only be grateful to him.”
