Juventus scored twice in extra time as the Serie A champions beat nine-man Napoli 4-2 in the Italian Super Cup at Beijing's `Bird's Nest' stadium on Saturday.
The team from Turin had to come from behind on two occasions and a bad-tempered period of the game saw Napoli reduced to nine men moments before the regulation 90 minutes finished at 2-2.
Juventus seized the win in extra time with Napoli fullback Christian Maggio scoring an own goal and Montenegrin striker Mirko Vucinic putting the game beyond doubt.
Juventus had come into the game the day after the unsettling news that coach Antonio Conte has been banned for ten months following an inquiry into match-fixing.
But it was a sweet victory for the club's number two Massimo Carrera - who is taking charge during Conte's absence - particularly as Juventus' last competitive defeat was at the hands of Napoli in the Coppa Italia.
Juventus did not look like the team that had won all but the final game of last season during the opening half, and just before the half hour Napoli broke the deadlock with a well-taken goal from Cavani.
His initial shot was well saved, but Cavani kept his composure, raced back to collect the ball, and then drove it past the Juventus captain as he was still getting back to his feet.
Juventus were soon level via a Kwadwo Asamoah volley, but Napoli hit back thanks to a clever chip by Macedonian Goran Pandev which looped over the keeper.
Napoli's aggression in defence proved their undoing when Juventus drew level again through a penalty, the referee having no hesitation pointing to the spot when Vucinic was pulled down in the box.
Vidal coolly slotted the spot-kick to De Sanctis' right to level the scores and set up a frenetic final fifteen minutes of normal time.
Pandev was the first player to be sent off after he appeared to insult a referee's assistant on 85 minutes, Juan Camilo Zuniga then dismissed following a second yellow card.
Juventus went ahead seven minutes into extra time when Maggio headed into his own net past a desperate De Sanctis before Vucinic confirmed victory moments later.
