Balotelli has long been considered an enfant terrible because of his propensity for getting into trouble on and off the field. However, Mancini, who coached the striker at Inter and then signed him for City, never lost hope that the 21-year-old would grow up and realise his potential.

"And against Spain in the final, I expect that he will carry the team. The moment of his consecration has arrived."
Mancini also claimed that he knew Balotelli would net a double against Germany, though he was disappointed that the forward removed his shirt after his second strike, thus earning himself a booking.
"I was sure that Mario would score two goals; I felt it," the former Azzurri international stated. "I thought it was his night and that he would make a difference.
"What did I think after the second goal? That he would have been able to score another. But it was a shame that he took off his shirt. He should not have gotten himself booked."
Italy will now face Spain in the tournament decider in Kiev on Sunday, with the game set to kick off at 20:45CET.
