Spot on.
Elia hasn't done anything to warrant a starting position yet.
Delps and Quags to start. Matri has been starting far too long, and might be losing motivation. Give him something to think about.
I think we are already playing 4-4-2, a flexible 4-4-2 where a midfielder or 2 become an attacker when Vuci or Matri moves back and create some space upfront.
I think DP can fit in the formation, but we'll probably see Quag.
