Roberto Mancini pessimistic on United derby prospects

Manchester City manager Roberto Mancini says his team are not "100 per cent ready to play" in Sunday's FA Community Shield match with rivals Manchester United.

Mancini also says he expects Carlos Tevez to be professional and show commitment to City, because he has no other team to play for, but can not say if he will still be with the club in a month's time.

Tevez is still on leave after the Copa America and is not expected to report back to the club until Monday.
