Napoli skipper Cannavaro: Dzeko is Man City's most dangerous
He insisted the Bosnian striker is now the Blues' biggest threat.
"We are ready, but I fear, above all, Dzeko," said the centre-back. "For me, he is the best centre-forward at the moment.
"I played against him last year when we played a friendly against Wolfsburg and he was really difficult to mark. He is so strong physically."
