Eight of those have come in Europe – including two hat-tricks – and, ahead of facing Lyon in their last-16, first-leg clash, Dzeko spoke about hitting his peak.
"I'm 30, nearly 31, and I admit that this is maybe my best season ever," he told UEFA.com. "I do not feel 30 years old.
"I'm fit and I am ready, but it's no accident – I work a lot, before and after training.
"Scoring three goals in one game is not easy, but when I do it in the Europa League it motivates me because I know I've achieved something big.
"It motivates me to keep scoring. I think those are my only two hat-tricks in the Europa League and I hope there are many more to come."
