The Champions League last-16 second-leg tie between Napoli and Eintracht Frankfurt was marred by violence as visiting fans clashed with police in ugly scenes in Naples before the game.
Around 600 Frankfurt fans descended on the Italian city despite being barred from attending the second leg after unsavoury incidents between supporters before the first leg in Germany last month.
Car windows were broken and fans hurled flares, chairs and other objects as innocent bystanders took shelter in bars and restaurants. A police car and other vehicles were set alight.
Police in riot gear eventually managed to calm the situation, shepherding the fans onto buses to take them to their hotels.
Further clashes were avoided as the majority of Napoli “ultras” were stopped from coming into contact with the German fans. They did throw stones and bottles at the buses, however.
Matteo Salvini, Italy’s deputy prime minister, wrote on Instagram: “These are not fans, they are criminals, thugs. I wonder if they would make the same mess in Germany?”
Police had been on high alert in the Italian city — around 800 officers had been deployed — as more than 600 fans arrived from Germany despite Frankfurt forgoing its allocation of tickets for the round-of-16 match in protest. That number was boosted further by Atalanta ultras, who have a bitter rivalry with Napoli.
The German club was objecting to a decision by local authorities in Naples banning any fans who are residents of Frankfurt from buying tickets, following unrest between supporters during the first leg in Germany.
Napoli won that match 2-0 but local police made several arrests in the buildup amid altercations between fans.
