Napoli striker Edinson Cavani believes that his side are capable of knocking Chelsea out of the Champions League.
The two sides were drawn together in the round of 16, with the opening leg to be played in Naples.
Cavani scored both goals as Napoli defeated Manchester City last month and the Uruguayan is confident that a similar result can be recorded against the Blues.
"I am always optimistic. If we have beaten Manchester City, we are also able to win against Chelsea," he told the Daily Star. "I am not unhappy with the draw. I am ambitious and want to win by defeating the best rival and this is a big chance.
"Them having the second leg at home does not worry us. At City's stadium we obtained a point, but the key will be in San Paolo.
"With our fans in Napoli we have nearly a goal advantage. That will be a big pressure to Chelsea."
Cavani, 24, joined Napoli in 2010 from Palermo.
