Hamsik: Napoli will use Juventus defeat as motivation
Juve defeated the Azzurri 2-0 on Saturday.
"Juve had a lot of the ball but never looked dangerous," he told Tuttosport. "Unfortunately we left Caceres alone at the corner, and we were punished.
"This defeat will give us the right sort of anger for the next games. We start next weekend against Chievo, and that will be important. We then go to Bergame [to play Atalanta] and that will also be tricky.
"We have to work hard."
