The Spaniard is remaining upbeat regarding his side's chances of mounting a title challenge after pointing to their point tally at this stage of the season compared to last.
The Partenopei are currently third in Italy's top flight and sit 10 points behind Juve, but Benitez - who replaced Walter Mazzarri after he opted to leave for Inter during the summer - is happy with the campaign to date.
"It's been so far a satisfactory season for us," Benitez stated in an interview with Corriere dello Sport. "We have won 36 points in league, better than the past few years. To be above us, our opponents have needed to accomplish extraordinary feats.
"We are, however, participating in a marathon and still have 21 games remaining."
The 53-year-old was complimentary of both Juventus and Roma for their respective efforts so far this term but believes there will still be a few twists and turns before the season reaches its conclusion.
"With 60 points available, our fate has yet to be written," he concluded.
Napoli's league campaign resumes on Jan. 6 with a home fixture against Sampdoria after the conclusion of the international break.
