Manchester United could spring a derby day surprise with Tom Cleverley able to train on Saturday.
It was feared the Reds midfielder could be out for up to a month after he limped out of Wednesday's Champions League defeat to CFR Cluj with a suspected calf strain.
But the 23-year-old has made decent progress in the last 24 hours and United will make a final assessment after the final training session at Carrington.
United travel to the Etihad Stadium on Sunday afternoon to face Manchester City with a number of question marks over their squad.
Nemanja Vidic has trained well all week and although boss Sir Alex Ferguson has stated the game with City has come too early, the Blues would not be surprised to see the Serbian take his place at the heart of the Red Devils' rearguard.
Nani and Anderson are definitely out, but Shinji Kagawa and Antonio Valencia may have done enough to make the substitutes bench.
The game of bluff is equally in play from City boss Roberto Mancini. Both David Silva and Gael Clichy have shaken off injuries and are expected to come straight back into the side.
United are 29.00 to beat their city rivals 3-2, and are 4.50 to keep a clean sheet. A 2-2 draw can be backed at 11.00.
