Well then, I just noticed 3 things that are wrong in your tactic. First of all, Maxi Rodriguez can't be defending. You're wasting him and ruining your midfield up. switch him with Lucas. Second, play Raul Meireles and Maxi in box-to-box role, and lucas in ball recovery. that way you can attack while being able to defend.
Next (your minor mistake),play Dzeko in the right side of the attack, with the role of Complete Forward - Attack. Then give Torres the Poacher role. They will score tons of goals.
Try it, and please tell me if it worked.
Bye
