Napoli are also proving to be difficult to break down in defence, with the two-time Serie A winners keeping clean sheets in their last three games.
Benitez was dealt a blow before the international break when star man Lorenzo Insigne suffered a serious knee injury during the 1-0 win against Fiorentina, which is likely to keep him out for the remainder of the season.
Cagliari head to Naples having won just once in six fixtures but with just a four-point margin keeping them out of the top half of the table, Gli Isolani will be content with their start to the campaign.
Head coach Zdenek Zeman will take confidence from his side's emphatic victories over Inter Milan and Hellas Verona on the road with four goals being netted in each fixture.
