Juventus ace Fabio Quagliarella believes the title race will be super competitive.
AC Milan and Inter Milan are still being considered as title contenders too despite their problematic start to the campaign.
"Are Napoli and Juventus good enough for the title? We are talking about two great teams," said the former Azzurri man.
"Napoli are really strong this season," he continued. "I think it'll be a great championship, but it will be a long and hard battle to win the title."
