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(www.menmedia.co.uk).
Balotelli, 22, left the training session hastily before driving away from the Carrington complex.
Balotelli last month accepted a club fine of 340,000 pounds ($553,700) for misdemeanours on and off the pitch and Mancini said he was ready to give him another chance.
