The Derby D’Italia started slowly and gradually gained momentum.
Juventus and Inter Milan played out a 1-1 draw in Serie A at the San Siro.
It took 73 minutes to break the deadlock, with 20-year-old Argentinian striker Mauro Icardi lashing a powerful shot into the Juventus goal with his first touch of the ball.
Arturo Vidal levelled the game just two minutes later in a tense game, showing quick feet inside the box to snatch the equaliser for Juve.
The result means Napoli leapfrog both sides and sit in top spot with nine points from three games, both Inter and Juve have seven points.
