"It's one of the best games of my life, as to win against a side like Juventus is remarkable," the Spaniard told Rai Sport.
"We dedicate this to all the Napoli fans who were with us today and watching from home.
"Rafael was excellent, Higuain made the difference in attack, but the whole team did well, everyone deserves this title."
