I believe that we are yet to see the best of Edin Dzeko. When City put crosses in the box, he gets on the end of them - the Blackburn home goal best illustrated this in my mind. He also scored decent headers against QPR and Spurs away.
I think Mancini likes the idea of playing with overlapping full backs sending crosses on to the head of a main striker and it was only his slight loss of form (and the return of Tevez) that led to him being on the bench.
I'd like to see us stick with the 4-2-3-1 with Dzeko at the front of that formation
Hart
Zaba, Kompany, Lescott, Clichy
Barry, Yaya
Silva, Aguero, Nasri
Dzeko
