Napoli moved level with Liverpool at the top of Group C after coming from behind to earn a 1-1 draw against Paris Saint-Germain in their Champions League clash at the Stadio San Paolo.
PSG controlled proceedings in the first half as Napoli attempted to nip at their heels with a flurry of counter-attacks.
Kalidou Koulibaly put his body on the line to block Marco Verratti’s effort before Dries Mertens and Insigne went close at the other end of the pitch.
But it was the visitors who drew first blood when Kylian Mbappe made a darting run into the Napoli box seconds before half-time, seeing his pinpoint pass calmly swept home by left-back Bernat.
Juan Bernat gave the French side the lead just before half-time with a close range finish.
The goal sparked furious protests from Napoli, who felt the ref should have blown for the break moments before.
And there was a steely look on Carlo Ancelotti’s face as the second half kicked off, with the hosts clearly determined to deal some damage of their own.
It didn’t take long for Mertens to draw three quick-fire saves from Buffon before the 40-year-old gave away a penalty for clumsily clattering Jose Callejon.
Local hero Insigne stepped up to fire in a ferocious spot-kick and salvage a point for his side, leaving all to play for in the final two game weeks.
Napoli host Red Star Belgrade in their next match, while PSG welcome Liverpool to the Parc des Princes.
