I usually play 4-2-2-2 with two central midfielders and two wingers (both wing-backs as well) at Citeh. I usually go with Jo and Robinho up front with Petrov and SWP as wingers, midfield usually rotates but generally contains 2 of the Johnson, Elano, Gelson and Kompany. My back four is usually always Garrido-Dunne-Richards-Zabaleta, though Onouha usually comes into consideration as Zabaleta goes through some rouch patches.
This is all basic squad though. Haven't played 09 so I don't know the ins and outs but I'd suggest going after a good left back and a better right back. Zabaleta is generally poor in the FM games I've played, perhaps go after Rafinha from Hertha or something.
