Nemanja Vidic not ready to return for Man Utd: Ferguson

Sir Alex Ferguson reveals captain Nemanja Vidic "won't be available" for Manchester United's Champions League tie against CFR Cluj-Napoca despite admitting he is concerned about his side's recent defending.

The Serbian had not been expected to return before Christmas following a serious knee injury, but despite being back in training Ferguson believes Sunday's derby against arch-rivals Manchester City will also come "too soon" for the centre-back.

Ferguson promises to field a side that can win against Cluj despite have already won Group H, as Cluj, Braga and Galatasaray could all still qualify for the knockout phase of the tournament.
