A first-half Goran Pandev brace proved enough to earn three points at the Luigi Ferraris, as the Partenopei overtook Roma at the top of the table.
Benitez was praised for his brave decision to leave some star names out of his starting line-up, but the former Liverpool boss felt he was merely being prudent.
I am consistent rather than courageous, the Champions League winner told Sky Sport Italia.
I have experience and have been in Europe many times, so I know squad rotation is necessary to make everyone in the side stronger. The team won with character.
Despite keeping a clean sheet, and having conceded just four goals in six matches, Benitez believes there are still some cracks in Napoli's defence that need repairing.
I didn't like some things, as we allowed too many crosses into the box, but it's not easy in these conditions, Benitez said. But I thought the game was closer to 3-0 than 2-1 all the way through.
Benitez added that Napoli's supporter base was putting high expectations on the squad after a strong transfer window for the club, but did concede that he feels that there is still a lot more to come from his side.
It is tougher for the fans, as they see the team winning almost every game and think we can win everything. We know that's not the case, he said.
