Marek Hamsik believes home advantage could be vital as Napoli look to qualify for the last 16 of the Champions League.
The Azzurri are level on six points with Borussia Dortmund and Arsenal after winning at Marseille on Tuesday.
“The battle for qualification is wide open and will be tough,” the Slovakian commented ahead of San Paolo ties versus Marseille and Arsenal.
“We hope to make the most of playing two of our next three games in Naples. I have the feeling that everything will be decided in the last tie [against Arsenal].”
Rafael Benitez’s men again impressed in midweek by collecting a 2-1 victory in France.
“We played really well and deserved the win,” the former Brescia man added. “We started well immediately and took our chances.
“It was important to end the first half with an advantage.”
