Roberto di Matteo is already facing a battle to win over the Chelsea dressing room.

The Daily Star says he is struggling to impose himself with the players because he is so unpopular in the dressing room.

Despite being a former Blues player, the Italian has done little to get the squad on his side since his arrival last summer as assistant manager.

He is seen by many as being arrogant and aloof - and with owner Roman Abramovich only giving him the job until the end of the season, he is set to have his authority tested by the club's powerful stars.
