Zola believes that Benitez has all the tools at his disposal to mount a sustained title challenge this season, rating the Spaniard as a top coach.
He told Corriere dello Sport ahead of tonight's clash between Napoli and table-toppers Roma: "They are the two clubs who should cause Juventus the most issues.
"Roma have impressed me with the results achieved so far and in the way they have collected them. But Napoli have a great coach and they really are not missing anything in order to target the Scudetto this season.
"I'm sure it will be a beautiful game tonight."
Both Roma and Napoli are unbeaten heading into this evening's meeting at the Stadio Olimpico.
