Mario Balotelli has thrown darts at team-mates, set off fireworks in his bathroom and scored brilliant goals.
He is childish off the pitch, but on it you see a whole new side of him. With his speed, strength and shooting ability, he is destined to become a great.
It all started in 2005, with an unsuccessful trial at Barcelona. Inter Milan spotted his talent and snapped him up in 2006 - they could see that he was destined to be great.
At Inter, he blossomed and slowly started to become a regular. The problem was that he wasn't getting enough playing time. With Zlatan Ibrahimovic and David Suazo ahead of him, he didn't start enough. However, when he did, you could see that one day, he would earn the nickname "Super Mario".
Manchester City saw it and subsequently swooped in with a hefty £22.5m bid in August 2010. Inter were happy to agree and made a huge profit on the temperamental striker. He was reunited with his former manager Roberto Mancini, who thought that "Super Mario" would be suited to the Premier League.
With his technical ability, he astounded the pundits and silenced the critics. Despite his "bad boy" behaviour he still shined. Then, once again came the problem of playing time, the "Why Always Me" a thing of the past. Several fights between the manager occurred and City realised that he had to go.
Finally, after a weeks of rumours, AC Milan came in with a bid. He was soon transferred and the Inter fans were extremely upset. Their rising star now sold to sworn enemies? Unacceptable.
Nevertheless, after signing for AC Milan in a transfer worth £19.5m, he is having a blast. Scoring seven goals in six games, there is no doubt of his starting position, and great things are to come from him.
With Italy, he has been simply sublime. At Euro 2012 he was the joint-top scorer, carrying Italy to the final with two crucial goals against Germany in the semis.
All this at the age of 22. With this kind of potential, Balotelli is bound to be one of the greatest players to grace the game.
