Walter Mazzarri wants to see a reaction from Napoli when they play Genoa after suffering back-to-back defeats in Serie A.
Napoli have seen their title challenge fade in recent weeks, but there is still a chance of finishing the campaign in second place.
"The game against Genoa is not decisive because there are another three still to play," Mazzarri said.
"However we have never lost two games in a row since I've been at the club and it's the moment to show our attributes.
"I am counting on the fans' support in this game, which will be very difficult.
"We have to fight until the end to finish this fantastic season. We never pose any limits on ourselves. We have four big finals ahead of us and I want to get maximum points.
"Until this year Napoli weren't used to competing in the upper echelons of the table, but in two years we have done extraordinary things."
