Juventus defender Leonardo Bonucci admits they let themselves down in defeat to Napoli.

Bonucci says the result showed Juve still did not have the title sewn up.

"I must congratulate Napoli for a great performance," Bonucci wrote on his official website. "Our opponents last night deserved it more than we did.

"What this defeat really showed me is firstly that the Scudetto is still not won, and secondly that it will keep our feet on the ground.

"You can always learn more. Napoli showed that they had more hunger than we did yesterday.

"The Juventus that I know has always shown more hunger than their opponents."
