Manchester United boss Sir Alex Ferguson concedes Wayne Rooney could be unhappy if he is rested again as he was against Fulham.

There is no guarantee the England hitman will walk back into the team once he recovers from his injury.

And Fergie admits it could affect Rooney if he is left out of the starting XI again, like he was against Fulham, once he is fit.

He said: "It could. Players like to be playing every week. For now it is only one game, so it's not a problem at the moment."
