Balotelli is a big money target for Mancini at City.
He said: "It is difficult not to talk about a great player who at times does wonderful things on the field and then has some irritating attitudes.
"I can only speak well of him because he behaved with me and was always professional. When one is young, there can be the odd mistake. This is to be allowed.
"He is 20 years old, I think he is the future of Italian football and hope Marcello Lippi will consider him, as he'd be of use to the Nazionale in South Africa. When someone is world class, he is world class! Waiting a few months won't make much difference."
