Napoli skipper Paolo Cannavaro rates Manchester City striker Edin Dzeko as the Premier League leaders' most dangerous player.
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."
