Struggling Napoli shock Sarri's Serie A leaders Juventus

Piotr Zielinski and Lorenzo Insigne scored in the second half as struggling Napoli shocked champions Juventus 2-1 to spoil coach Maurizio Sarri's return to the Stadio San Paolo.

Sarri had not been back to Naples since being sacked in May 2018 after three successful campaigns, and before moving to Chelsea.

This season he has taken over eight-time reigning champions Juve, a move seen as a betrayal by his former team, the two-time Serie A runners-up.

Juve missed the chance to open up a six-point lead on Inter Milan at the top of the table, after Antonio Conte's side were earlier held 1-1 by Cagliari, their third consecutive draw.

"It's a victory for the whole of Naples," said Insigne on Sunday after his team's first home win in the league since October 19.

Inter are three points behind Juve with Lazio a further two points adrift in third after city rivals Roma ended Simone Inzaghi's side's 11-match winning streak.

In Naples, Zielinski broke the deadlock after 63 minutes finishing off a rebound after Insigne was denied by Juve goalkeeper Wojciech Szczesny.

Insigne volleyed in a second after 86 minutes to an explosion of joy among the crowd.

Cristiano Ronaldo pulled a goal back as the game headed into injury time for his 13th goal in nine consecutive games in all competitions.

The visitors pushed for the equaliser but Alex Meret smothered Gonzalo Higuain's goal-bound effort, as Juventus crashed to just their second defeat of the season.

Napoli move up to tenth place, 12 points off the Champions League places after ending a run of three consecutive defeats.
