Both sides are looking to win the Champions League clash on Tuesday as they look to progress to the knock-out stages.
Cavani said: “I’d like to score to reward the fans and give them something to celebrate. I will give everything to Napoli, who have a big faith in me.
“I want to score for my team, for the club, for the coach, for the people. For us the Champions League is a really important competition. We need points and a win would be good.
“Their aim is to progress to the next round, so they will come here to play their game. We must take advantage of the space created because we need points too.”
