Nemanja Vidic and Rio Ferdinand are doubts for Manchester United ahead of tonight's clash with Real Sociedad at Old Trafford.

The defensive duo both missed training yesterday. Phil Jones and Jonny Evans may be tasked with starting in the centre of the back four.

Tom Cleverley and Danny Welbeck are also doubts for the Champions League tie with a calf injury and a knock picked up against Southampton respectively.

However all four could still play some part tonight, particularly Cleverley and Welbeck whose injuries are not serious.

Team news from Moyes: "There are a few knocks & niggles. Vidic & Rio are making progress, Welbeck & Cleverley have a chance to play." #mufc
