Slovakian playmaker Marek Hamsik has warned Chelsea that they face a "confident" Napoli side in the Champions League tomorrow.
The Italian club travel to Stamford Bridge with a healthy 3-1 advantage, and Hamsik has said that they will not throw the lead away.
"We saw the Arsenal-Milan match last week and we have to make sure that does not affect us - if we use the same tactic as Milan that would be a disaster," Hamsik said.
"Chelsea have had problems and we need to exploit their weaknesses and doubts. We need to score and if we can do that then I believe we will go through.
"We're going to Stamford Bridge to enjoy the game, to play and we're confident of getting through."
Napoli boss Walter Mazzarri has been banned from the touchline for the tie after pushing an opposition player during a match in December.
