West Ham supporters in Seville violently clashed with Eintracht Frankfurt fans last night with the two teams in Spain for Europa League matches.
German side Frankfurt defeated Real Betis 2-1 on Wednesday night and West Ham fans were already in the city ahead of facing Sevilla on Thursday.
Betis' match with Frankfurt had been brought forward 24 hours by European football's governing body UEFA in a bid to avoid crowd trouble.
But footage emerged on Wednesday of Frankfurt and West Ham fans clashing violently in the centre of the city.
