"He didn't do well to seek motivation here at Al Nasr," said Zenga.
"I didn't like what he said in the papers and those comments do him no credit. A player must find motivation even when there isn't any.
"Here he did what he was meant to do, but also dislocated his elbow and was out for 42 days. Therefore, he missed a lot of the games.
"I imagine he can play at Fiorentina, it all depends on if his mind is on the job."
