The Giallorosso haven't won a title for 11 years.
“It's such a shame for a club like this not to have won anything in the last years," Dzeko told the Athletic. “Hopefully this can change, because this club, first of all, deserves to win trophies.
“There's everything you want, everything you wish for in this club. We just need this last step: to win some trophies. Every trophy gives you more confidence and more belief that you can reach even higher, higher things.
“I have to say the club has grown so much in the last four years and it's getting bigger and bigger every year."
