The Rossoneri chief has revealed his side are in talks with Inter regarding a possible signing of the defender
The Rossoneri are looking to bolster their defence ahead of the upcoming campaign and the club's chief has now revealed that they have enquired about signing the Argentine from their San Siro rivals.
"We're in talks with Inter for Silvestre," the 68-year-old told reporters. "Now I will meet with the Inter directors to find an agreement.
"We still haven't agreed upon what kind of deal it will be for Silvestre."
Meanwhile, the Milan vice-president is hopeful of a quick recovery of Robinho, who suffered a thigh injury in late July, while insisting that youngster M'Baye Niang will not be loaned out until the end of August at the very earliest.
"We're counting on having Robinho ready for the Champions League play-offs," Galliani added. "If Niang leaves Milan then it won't be before the play-offs."
The 28-year-old centre-back has made 20 appearances in all competitions for the Nerazzurri last term.
