Kalidou Koulibaly scored a spectacular own goal in stoppage time to hand Juventus a stunning 4-3 victory over Napoli in a thrilling Serie A clash on Saturday night.
Napoli had fought from three goals down at the Allianz Stadium, but their hard work was undone by Koulibaly goal on 93 minutes.
Goals from Higuain, Danilo, on his debut and Ronaldo seemed to have been enough to hand the defending champions a win over one of their key rivals, but Manolas and Lozano scored within the space of two minutes before Giovanni Di Lorenzo grabbed a late equalizer.
With the Carlo Ancelloti-led charges seemingly taking a point, Koulibaly sliced a freekick into his own net deep into extra time, following a sumptuous freekick front the right wing.
Juventus threatened early on with an effort from Ronaldo, but Napoli goalie saved spectacularly to deny the Portuguese.
Napoli hit back almost immediately with an attack of their own, which Szczesny saved, before Danilo gave the home team the lead with his first touch of the match, having replaced the injured Mattia De Sciglio.
It was a blistering counter-attack led by Douglas Costa that caught the visitors napping at the back, with the summer signing getting at the end of the Brazilian's pass to finish.
It was 2-0 a minute later, this time Gonzalo Higuain finishing after Napoli failed to clear a freekick inside their box.
Napoli came back the stronger of the two sides in the second half, but it was the home team that once again scored, this time Szczesny unable to deny Ronaldo from inside the box as the scoreboard changed to 3-0.
The visitors, however, hit back with two goals in two minutes, before Di Lorenzo scored late on to pull them level, only for Koulibaly to score an own goal in added time to deny them a point.
