Udinese and Napoli hooligans clashed on the pitch at the Friuli stadium after Napoli clinched the Serie A title.
Thursday night’s match between Udinese and Napoli ended in a 1-1 draw and that was enough for Napoli to clinch the Serie A title for the first time since 1990.
As soon as the final whistle was blown, Napoli fans raced onto the pitch to celebrate.
A number of Udinese hooligans also came on to the pitch and clashed with their Napoli rivals.
Some photos show several men using their belts as weapons to strike their counterparts.
