I fancy a 4-4-2 for this game. Sunderland shouldn't be threatening enough to pack the midfield that much.
I'm saying:
Hart,
Richards/Zab, Kolo, Kompany, Lescott
Johnson, Barry/NDJ, Yaya, Milner/Silva
Tevez, Balo (if fit)
Barry/NDJ and Yaya will have to keep back a bit in this formation to help out the "weakened" defense perhaps unlike in Liverpool with 3 holding there was scope for 1 to push forward (Yaya)
These are the sorta games we should be hammering in 5-nils. Set some pace on the campaign/put the fear of god in the top 4! Although saying that, perhaps Mancini won't want to field a full strength team due to risk of injury/rest etc.
