The Slovak is over the moon after a historic victory in Turin but warns the Azzurri against complacency.
Midfielder Marek Hamsik netted a fantastic brace to give the Partenopei their first away win over Juve in 21 years and could barely contain his enthusiasm after the encounter.
“We are very happy at this win,” he beamed on Sky Sport Italia.
“The coach told us at half-time that we were not playing that bad and we did good in turning the game around in the second period.
“The boss is doing so much and has instilled a great spirit. We wanted to win this match.
“I like this system, but we must still work and improve. Now we must keep our feet on the ground and take one game at a time.
“I dedicate the goals to my girlfriend who will soon give birth to my son.”
Napoli have managed three wins and one draw since Mazzarri took over from Roberto Donadoni last month and have now temporarily climbed into fifth in Serie A ahead of today’s games.
