Italian police arrested eight people overnight after fighting broke out among fans in Naples on Wednesday as Napoli faced Germany’s Eintracht Frankfurt in the Champions League, Alessandro Giuliano, Naples police chief, said.

Five of those held were Napoli supporters and the other three were visiting fans from Germany, Giuliano said.

The Italian authorities banned fans living in Frankfurt from attending the match amid concerns about possible violence, but a group of supporters made the trip anyway.

Footage showed supporters clashing with anti-riot forces and a police car in flames, with objects being tossed towards the police while overturned tables and chairs lay smashed on the ground.

“These are not fans, they are criminals, thugs. I wonder if they would make the same mess in Germany?” Italy’s deputy prime minister Matteo Salvini wrote on Instagram.
