City boss Roberto Mancini has already expressed public concerns about his new centre forward's struggle to adapt to the frenetic and physical nature of the English domestic game. Dzeko is not worried, though. He has been here before.
"When I first went to Germany I didn't play very well," he told the Daily Mail.
"For about a half a year I didn't do what I can, and I think people must have thought I was hopeless. But then I got used to the league and to the team and then I began to do what I can do.
"I know that I have to do that quicker here, but playing for a big club in the best league in Europe has always been my big ambition - and it's come true. It's different and harder than the Bundesliga. You have to always be strong and fight for every ball.
"The referees are different too. They don't whistle as they do in Germany, where every small contact is a foul. Here [he punches his fist into his palm] it's no foul.
"Away at Notts County [in the FA Cup] it was hard because the pitch was small and it was like a fight for 90 minutes.
"There was no football there, but I know I can play football and I want to show that."
