You didn't answer my questions, but thanks for trying.
Dzeko is going to score the same way he always does...own his own, crosses, one two's, counters, corners, FK's, PK's, hell he might even take on 3-4 defenders on his own, I wouldn't put it past him he has done it before. That should more than answer your question.
He has score over 40 goals in 2 seasons and if you watch them all of them (not even half) are from crosses.
