Napoli visited Spezia in the final matchday of the Serie A season, a game in which, despite there being nothing in play, saw ugly scenes in the stands. The referee Marchetti saw the game halted in the 12th minute.
After Matteo Politano's goal, according to 'La Gazzetta dello Sport', ultras from the home team threw bottles and smoke bombs towards the Napoli fans. In that moment, away fans reacted by invading the neighbouring area and that led to fighting between the fans.
Immediately, the players tried to calm things down and the stadium's security had to go onto the field of play to prevent things getting out of hand. Finally, after a more than 10 minute delay, the match resumed in the 23rd minute. Napoli won, this sort of "friendly" by now, 3-0.
