Ermin Zec is nothing like Dzeko, unfortunately. He's short, very quick, and a good dribbler (prototypical Balkan style player). I don't see him making it in the EPL anytime soon, he is more of a Primera Division player.
The next big Bosnian signing in the EPL should be Miralem Pjanic, from Lyon. Arsenal Wenger has been interested in him for a while now.
