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.
