Manchester United assistant boss Mike Phelan admits they're keen to "settle down" their defensive injuries.
Nemanja Vidic picked up a calf strain in the win against Wolves on Tuesday.
And Phelan says: "At the moment we're probably going to end up playing with one defender and nine attackers. We've got time to settle down now, we play Saturday (against Fulham), we'll have a look at the issues tomorrow. We know Nemanja (Vidic) came off with a slight problem, we just hope that he can recover in time."
