Sampdoria chief Beppe Marotta admits Antonio Cassano's contract carries a buyout clause.

He revealed: "We have not talked to anyone, but we know that Juve are interested in the player. We've talked to Antonio, in the next few months anything can happen.

"He said he is fine here, but there is a buyout clause that allows him to free himself when he wishes. I, however, think that he will remain."
