Dzeko concedes life as a bit-part player is difficult, but with so much talent in the squad, each player must accept some time on the bench.
He told The Sun: "There is myself and three fantastic strikers so obviously we can't all play at the same time. 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."
