Dzeko has admitted being in and out of the side does not allow for City's forwards to establish any kind of consistency in their form or understanding with their fellow forwards.
"There's myself and three fantastic strikers so obviously we can't all play at the same time," said Dzeko.
"So sometimes it can be difficult to find your rhythm. You could play one game and then be on the bench for the next three.
"I think confidence is the key to playing at your best, of course. Plus the more games you play, the more goals you are likely to score.
"But, as I say, with many good strikers at the club that's how it's going to be. As a player, you accept that and just try your best each time you play.
"That's what I do and will continue to do. I've always wanted to stay at City and fight for my place.
"My motto has always been, 'Never give up'. I hope the City fans who have always been fantastic towards me have seen I can score important goals for the team."
