Rosanero president Maurizio Zamparini has revealed he is nearing an agreement with Nerazzurri supremo Massimo Moratti over the Argentine defender's transfer
The Sicilian outfit's president Maurizio Zamparini has claimed that negotiations with the Nerazzurri are in the final stages and a deal could be struck soon.
Silvestre, 27, already announced his intention to leave Palermo after just one season with the Rosanero and has been linked with both Inter and AC Milan.
Andrea Stramaccioni's outfit had originally offered €7 million (£5.6m) for the defender, who also holds an Italian passport, but have now upped their bid in order to ward off competition from their city rivals.
"I met with Inter president Massimo Moratti. We spoke about Silvestre and we are on the same page," Zamparini told Radio Radio.
"There is a 99 per cent chance that a deal will be done. It will be a transfer worth around €8m to €10m."
Silvestre moved to Italy from Boca Juniors in 2008 and spent three seasons at Catania before making the switch to Palermo last summer.
The defender, who has a contract with the Rosanero until the summer of 2015, scored five goals in 29 league appearances last season.
