Manchester City manager Roberto Mancini was involved in a training ground bust-up with volatile forward Mario Balotelli Thursday, the Manchester Evening News reported.

Italian striker Balotelli provoked Mancini when he mistimed a tackle on midfielder Scott Sinclair and the pair tussled as coaches tried to separate them, the paper said on its website.

Balotelli, 22, left the training session hastily before driving away from the Carrington complex in his camouflage car.
