The Italy international is also wanted by Tottenham.
Massara said: “We are concentrated on the game and our season. The transfer market is open, even if we already said that there are no particular needs, and we continue to maintain that.
"We'll see if there are any opportunities from now to the end of the window, but I consider that very difficult.
“We are absolutely convinced we have a strong squad, a great coach and are capable of competing at the highest level, which we intend to do to the end. We are recovering players from injury and expect a fine end to the season."
