I'd stick with the two up top and the defensive mid, but I'd play with 3 deep midfielders, supporting the front 2. You have the pace up front and the delivery in Arteta, maybe play Arteta as a deep lying playmaker [support], Rodwell as Ball winning midfielder [Support] and Cahill as a supporting midfielder. Play it through the middle with a narrow width and slow the tempo down. But barring all that, you shouldn't have much of a problem against most of the sides, just sticking with your current formation and slowing down the tempo would be just as effective.
