Juventus great Fabio Cannavaro says AC Milan sent a message with Sunday's win at Napoli.

Cannavaro insists Milan coach Stefano Pioli has what it takes to lead them to the Scudetto this season.

He told Il Corriere dello Sport: "He sent a message, yes, but to win it there is still a huge job to do.

"I still think that, given Juventus' evolution, it would be a huge mistake to consider Allegri irremediably excluded from the fight; and Napoli, who lost the other day, remain in the running.

"It's a challenge among four."
