Mario Balotelli cut short training at Brescia on Thursday amid claims of a bust-up with coach Fabio Grosso.

Gazzetta dello Sport has reported local sources have claimed possible tension between the two men during training on Thursday.

“Mario, go," the World Cup winner is said to have told the striker, who would have then left an hour into the session.

The 28-year-old was described as being “very angry" - however club officials insist there's no issues.

Grosso hooked Balotelli at halftime of his first game in charge in defeat to Torino.
