5. Mario Balotelli & Roberto Mancini

On Thursday, photographers snapped some compromising images of Mario Balotelli and his manager Roberto Mancini in an all out brawl. At one point, Mancini could be see trying to physically remove Balotelli from the pitch, before the pair began pushing and shoving each other and eventually had to be pulled apart by stunned staff and players. The incident was sparked by a tackle on Scott Sinclair, which Mancini believed was so bad that had it taken place in a Premier League game, two red cards would have been warranted.
The Consequence In the aftermath of the bust up, Mancini claimed the player would
not be disciplined by the club, ruling out a fine or possible suspension. Mancini also ruled out selling the player in the January transfer window. However, this is just the latest in a series of off-field incidents involving Balotelli, who is proving to be a distracting influence at the club. The Italian has only started two Premier League games this season, scoring just once. Though he may not be sold this month, he could be kicked out in the summer. Source(s):
