Napoli rotated their squad for the clash with Wednesday's Champions League game against Borussia Dortmund in mind and they were only able to break down Atalanta after Marek Hamsik came on.
Rafa Benitez pleaded with fans and critics to reserve judgement of his new side until later in the season and says that he needs his players to remain calm following their 100 per cent record from the opening three clashes.
"I am very satisfied, as we won and also rotated the squad to preserve energy," the Spaniard told Sky Sport.
"The key to this team is the cohesion of the group. The fans must always stay this close to us, as their support is fundamental.
"We’re top of the table, but we should stay calm, as it’s still early to judge."
