The situation erupted with Napoli leading 1-0 thanks to a Matteo Politano strike.
There was no reason for tension, because Spezia were already safe in Serie A and Napoli had secured third place.
It’s not clear how it started, but there was a thin line of stewards and a small barrier separating the two sets of ultras in the curva behind Meret’s goal.
According to DAZN, they began throwing things at each other, including fireworks, flags and plastic seats.
Players and both coaches rushed over in a bid to calm their supporters down, but some Spezia fans broke onto the pitch and were stopped by their players from reaching coach Thiago Motta, who is reportedly leaving the club.
Play finally resumed after circa 11 minutes.
According to Sky Sport Italia, Napoli fans considered it a ‘revenge’ attack for Spezia supporters ambushing some of their rivals before the match.
