I've never been a City fan but am a huge fan of Dzeko (it's a given, since I'm Bosnian). I have watched at least 90% of his games over the past couple of years, and have also watched City play just about every weekend over the past year or so...and can say one thing: He is exactly what you need to get past the big boys in the EPL. Not only does he score in bunches, but he assists and creates opportunities in other ways for teammates. Having said that, he has never quiet had the midfield support he now has at City....so his game could go to a whole new level!
Very excited to see how well he does. Just give him a few games to adapt to the EPL, then he'll be up and running for the long term.
