Napoli coach Walter Mazzarri feels Juventus are the title favourites.
The two teams meet today.
Mazzarri said: "The directors have invested well and Conte is an excellent tactician. At this moment they are certainly the favourites, including against us tomorrow. I see other teams in the running too, as it's too early to give a definitive opinion on the candidates for the Scudetto. All I ask from my men is to be a little more clinical than in recent outings."
