Mario Balotelli's Manchester City future has been thrown into doubt after pictures emerged of what appeared to be a furious training-ground bust-up with manager Roberto Mancini.

It is reported that Mancini stepped in after Balotelli went in too strongly in a tackle on team-mate Scott Sinclair for the City boss' liking.

Balotelli is reported to have taken exception to Mancini's intervention, leading to the pair having to be pulled apart.

He is then seen to grab hold of Balotelli's orange bib in an apparent act of fury before the young striker is dragged away by a member of City's coaching staff.

A short time later, Balotelli is believed to have left the training ground at Carrington, on the outskirts of Manchester.

Whilst it is not the first furious argument Balotelli and Mancini have had - the pair have exchanged words both on the training ground and in matches - it does come in a period where the City manager's faith in the striker is beginning to wane.
