Former Inter boss Rafael Benitez believes that Juventus have to be considered as Scudetto contenders.
"Juventus are among the favourites for the championship," the currently unemployed Spanish tactician told Eurosport.
"Milan and Inter haven't lived up to expectations so far and they have squads which are weaker than they have been in the past.
"Juventus, also thanks to their new stadium, have an extra gear. However, let's not forget Napoli either. They too are a side to keep an eye on."
Juventus, who beat Milan 2-0 on Sunday, are co-leaders of Serie A with Udinese. Napoli are just a point behind.
Milan and Inter are struggling with just five and four points respectively from the opening five games of the campaign.
