Rasmus Hojlund scored both goals as Napoli went top of Serie A with a 2-1 win over Juventus.
The Denmark forward, who is on loan from Manchester United, slid in to put the defending champions ahead before Juventus hit back when Kenan Yildiz equalised after a counter-attack.
However, Hojlund secured the points with his second, a 78th-minute header from point-blank range.
He now has six Serie A and Champions League goals for Napoli since moving to Italy on a season-long loan at the beginning of September.
Former Manchester United midfielder Scott McTominay nearly scored just before the interval when his header glanced past the near post.
McTominay was forced to visit the touchline several times for treatment, though he managed to play on.
Napoli have 31 points, one ahead of Inter Milan in second. Juventus are seventh on 23 points.
