But Maniero told TMW: "As a player I would never have gone, then everyone does what they want.
"We need to understand what is behind all this, only he knows if he is right to go there or not."
As far as a replacement for Ibra, Maniero nominates a striker from Torino: "I like (Andrea) Belotti most of all, he combines quality with overflowing physical strength. He is good with his head, at protecting the ball, at offering himself. He is a great team striker."
