Manchester City Stars Mario Balotelli And Jerome Boateng Clash In Friday's Training Session

Italian striker has a history of controversy

Manchester City players Mario Balotelli and Jerome Boateng had be separated by their team-mates in Friday's training session at the club's Carrington training ground.

Balotelli reacted angrily after a tackle from the German defender and the two were involved in a heated exchange before being pulled apart by fellow City players.

The duo later reconciled their differences but this latest incident will do manager Roberto Mancini no favours at a time when the Italian is denying that the mega-rich club have any problems inside their dressing-room.

Italian forward Balotelli is renowned as a troublesome character and fell out with former manager Jose Mourinho whilst both were at Inter last season, something that led to the 'special one' warning City against signing the forward.

"The guy has incredible qualities, but sometimes does not know how to use his brain," Mourinho told The Sun last summer.

City did not heed the warning and their £24 million summer signing has impressed in front of goal, most recently with a brace in the club's 3-0 win over Red Bull Salzburg in the Europa League on Wednesday.

However despite his undoubted talent, it is the youngster's attitude that has been a problem throughout his career - something City fans saw when he was red-carded in their 2-0 victory over West Bromwich Albion a few weeks ago.

One of Balotelli's team-mates at City, experienced midfielder Patrick Vieira, believes that the young striker needs to work harder if he is to fulfill his potential and become one of the top players in the world.

"I think he’s already one of the best finishers in the world," he said.

“But that’s not enough to make a career. He’s got to work harder – he’s still young and he’s got to improve his game a lot.

“I think if he does that he will be successful but he needs to work more for the team."
