Lorenzo Insigne’s penalty cannoned agonisingly back off the post as Napoli lost 2-1 to runaway leaders Juventus in a Serie A thriller that saw both teams finish with 10 men.
Miralem Pjanic converted the 28th-minute free-kick after Napoli’s young goalkeeper Alex Meret was sent off for a professional foul on Cristiano Ronaldo and Emre Can made it 2-0 before half-time.
Despite operating with reduced numbers, Napoli hit the post through Piotr Zielinski between the Juve goals and Pjanic’s second yellow card for deliberate handball gave them hope – as did Jose Callejon’s 61st-minute goal.
Insigne provided a superb assist but could not complete the comeback after Alex Sandro fell foul of a VAR review for handball having blocked Fabian Ruiz’s goalbound shot.
Napoli’s relentless pressure then dropped off and Massimiliano Allegri’s undefeated Juve now boast a mammoth 16-point lead over Carlo Ancelotti’s men at the summit.
