Manchester City coach Patrick Vieira has backed manager Roberto Mancini's handling of Mario Balotelli.
Mancini's tough streak came out last week when he reacted to Balotelli's showboating against LA Galaxy by substituting the Italian striker.
Vieira told the Sunday Mirror: "Mario can do some crazy things at times, but he also has all the skills to become one of the best players in the world - and that's why Roberto brought him to City. He will help him grow up and when the boy becomes a man - watch out!"
