Manchester City officials feel Mario Balotelli has turned the corner.

Balotelli is once again available for selection for tomorrow night's make-or-break Manchester derby with United after serving a ­three-match ban for his red card in the defeat at Arsenal.

A City insider told the Sunday Mirror: said: "There has been a noticeable change in ­Balotelli since his sending off at Arsenal.

"He has settled right down and seems to be focused on his job, which hasn't always been the case since he came to the club.

"A number of players have made their feelings clear to both Balotelli and Roberto Mancini that they felt one player was being given too much freedom.

"It was beginning to cause ­problems in the dressing room and was also damaging Mancini ­because to some extent he has staked his reputation on Balotelli."

The insider added: "All top players are given some ­concessions. That doesn't cause any problems as long as they are delivering on the pitch. The feeling was that Balotelli was not doing enough to be considered a special case."
