Juventus coach Antonio Conte was delighted with their victory over Napoli.
Conte says they made a statement with their 3-0 win.
"Napoli are a very, very strong side who can still improve," he told Sky Sport Italia after the 3-0 victory.
"Rafa Benitez said they are at 75 per cent, so they can still achieve a great deal and I'm convinced they'll fight for the Scudetto to the end.
"Last season they finished second and over the summer invested heavily on the transfer market. It was a great Juventus performance."
