"I'd be delighted," he told Sky Sport Italia. "First of all because Alessandro is a great player.
"He's turned out to be decisive for the National Team despite playing for Bologna, and we know how difficult it is to make an impact at a provincial team.

"I have known him for years. I hope he arrives here."
