The defender talked up the prospect of moving to Barcelona only last week.
But he now says: "Until the end of my contract I will stay at Milan, then we'll see. I just signed a new one with the Rossoneri until June 2016 and we'll see if there is time to enter into a marriage for life.
"Now I'm concentrating on the Copa America, but when I return to Italy I will speak with (Adriano) Galliani: I must explain myself."
"I have been telling him there is nowhere better than Milan," added Thiago Silva.
