Neither is Iaquinta. He scores 1 out of 5 chances presented to him, which amounts to a grand 20% conversion rate (and I think I am even being generous here); he has the first touch of a mule, and is sometimes extremely selfish.
Don't get me wrong, I am neither advocating the need for Dzeko, nor am I claiming he is better than Iaquinta. I am just attempting to be objective here.
As for your Bundesliga comment, within the coming 2-3 seasons they will steal Italy's 4th CL spot. Serie A is not the once "almighty" competition it used to be, as evidenced by our suicidal form (on 3 separate occasions when we had major blips) under Ranieri last season. However, we still managed to finish 2'nd, which goes a long way to showing the level of competition we were up against. Ibra and Kaka defecting to greener pastures also deems your disregard for the Bundesliga somewhat suspect.
