Form guide: After conceding a late equaliser to Southampton on Saturday, United are seeking a morale boost as well as three points to consolidate a solid start in Champions League Group A. The Reds have already beaten Bayer Leverkusen at home and earned a hard-fought draw away to Shaktar Donetsk; meanwhile Real Sociedad are without a point after losing their matches to those same teams. However, they were victorious at the weekend, for the first time in eight games, when they beat Valencia 2-1 away.
Ins and outs: Nemanja Vidic missed the Southampton draw with a calf injury picked up in training last week, but David Moyes is hopeful that the skipper - who turned 32 on Monday - will be fit in time to face Sociedad. The visitors' captain Xabi Prieto returned after a month-long lay off with a thigh injury in the win over Valencia. Esteban Granero, on loan from QPR, will miss most of the season after the midfielder picked up a serious knee ligament injury.
Betting: Our betting partners bwin have United as firm favourites at 1.45, while Sociedad are 6.50 while the draw is 4.33. How about a flutter on Adnan Januzaj making his Champions League debut and scoring first in a 2-1 win for the Reds at a tasty 29.00?
Last meeting: United have never faced Real Sociedad before.
