Marouane Fellaini has been ruled out of Manchester United's Champions League game against CSKA Moscow on Wednesday.

The Belgium midfielder was not in the squad that left Manchester this afternoon, having failed to recover from the ankle injury he sustained in Saturday's Premier League game at Southampton.

TV replays showed Saints striker Shane Long catching the former Everton man from behind, having got nowhere near the ball with his second-half challenge.

Senior United sources are understood to be furious at the tackle and the feeling at Old Trafford is that if Fellaini had been the transgressor, referee Craig Pawson would have taken action.

It is not known how long Fellaini will be out for.
