Napoli coach Rafa Benitez says his players have to be at their very best if they are to take anything away from Sunday's game against Juventus.
The Partenopei battled past the Bianconeri to win the Italian Super Cup last month and will have the support of their own fans when they host Massimiliano Allegri's side at the San Paolo Stadium tomorrow evening.
"The first difference between tomorrow's game and the Doha win is that tomorrow we play at the San Paolo," Benitez said.
"Our fans are behind us, more than ever, we saw this during our training sessions. I've said it before: hand in hand we can go far.
"The [Juventus] game is very important, we have to win to keep our positive run going. We know how strong they are so we have to be at our very best.
"We are focused on the job. Against Cesena I liked the attitude of the team, we showed personality and that's what we have to keep doing."
With Faouzi Ghoulam away on Africa Cup of Nations duty, Benitez will have to make changes in the defensive department and Miguel Britos is set to fill the void left by the Algerian.
"[Miguel] Britos is strong in the air, he's one of our most solid defenders in respect to physical strength. He's not a full-back, but he has great potential.
"He's an important player and the fans should support him because he's playing in a role that is not his, working hard to always give the best."
Asked if new signings Ivan Strinic and Manolo Gabbiadini could feature, the Spaniard said: "Both of them are working with the rest of the squad.
"Strinic didn't train for weeks because of an old injury but he's slowly recovering.
"Gabbiadini is ready, he was playing for Sampdoria, it's a matter of choosing together what role is best for him."
