Juventus, Napoli favourites for Serie A title: Walter Mazzarri

Rome: Inter Milan head coach Walter Mazzarri is expecting a two-horse race between Juventus and his former side Napoli for next season's Scudetto.

Juventus are favourites to win a historical treble but Mazzarri warned that Napoli could surprise everyone, reports Xinhua.

"Besides Juventus, I think that in terms of financial muscle and on the strength of the last four years, Napoli could be a notch above the rest. Along with Juve," he said.

But the beginning of the new season could be intriguing given no team can afford to lose from there, according to the Inter boss.

"There are at least six or seven teams, including Fiorentina and Lazio, who will be bunched together on the starting grid. It's hard to know who has got more quality, who can do better. It depends on how you work on the pitch, on whether you manage to exploit the players' ability to the maximum," he said.
