Chelsea have immediately lodged an appeal against the sending off of midfielder Mikel Jon Obi early in their 2-0 defeat at Manchester United on Sunday.

A club spokesman told a news conference after the game an appeal for wrongful dismissal was already under way.

Referee Mike Dean dismissed Mikel for a foul on Patrice Evra after 32 minutes.

"We were playing well until Mikel was sent off and the game changed. It seemed the wrong decision," said new Blues manager Avram Grant.
