Chelsea boss Andre Villas-Boas has said that Napoli will provide a difficult test when the two sides meet, following this afternoon's Champions League draw.
The Italian outfit defeated Premier League leaders Manchester City in the previous round of the competition, but finished behind German giants Bayern Munich in the so-called group of death.
As a result, Villas-Boas believes his side have one of the toughest draws possible.
"I think we have one of the most difficult draws," he told Chelsea TV. "But whichever team you get in the last 16 will be a difficult team.
"Napoli is a club that represents the city and the city has great empathy with the club. It has a tremendous fan base and it is one of the most difficult and exciting games of the last 16, no doubt about it.
"They are fully motivated and they have a lot of talent coming through like [Marek] Hamsik and [Edinson] Cavani. They have a lot of talent throughout."
Meanwhile, the Blues will look to continue their recent undefeated streak with a win at Wigan this weekend.
