Kalidou Koulibaly's stoppage-time own goal sealed Juventus a thrilling 4-3 home win against Napoli, who had fought back from 3-0 down.
Cristiano Ronaldo looked to have put the game beyond Napoli when he struck Juve's third goal just after the hour-mark following first-half goals from substitute Danilo, on his debut, and Gonzalo Higuain.
Napoli hit back as Kostas Manolas and Hirving Lozano scored within the space of two minutes before Giovanni Di Lorenzo looked to have snatched Napoli a point with a late equaliser.
But in time added on, Napoli's Senegal defender Koulibaly turned the ball into his own net to gift Juve their second Serie A win of the season in front of boss Maurizio Sarri, who was watching from the stands following a bout of pneumonia.
