Preview: Manchester City vs Manchester United
London: Manchester City`s main injury problems lie in defence, but Gael Clichy (ankle) is set to return for the Premier League champions, with fellow left-back Aleksandar Kolarov (groin) also close to full fitness.
James Milner (hamstring) and Micah Richards (knee) are likely to miss out for the home side, while Jack Rodwell (hamstring) should be available for selection for Roberto Mancini.
David Silva (hamstring) is a worry for the hosts, and could be replaced by Javi Garcia in the centre for a more defensive formation.
The visitors have injury problems in midfield, with Anderson (hamstring) likely to miss the festive period after picking up a knock against Reading, and Tom Cleverley (calf) also a doubt.
Antonio Valencia (thigh) and Nemanja Vidic (knee) could both be available for selection, although Sir Alex Ferguson has said he feels the game will come to soon for the Serbian captain after a second long spell out.
Nani (hamstring) is almost certainly out of the game, while Shinji Kagawa (knee) could take a place on the bench after time on the sidelines.
