Riot police in the Polish city of Wroclaw deployed water cannon on Chelsea and Real Betis supporters after trouble broke out before the Conference League final. The two sets of supporters were involved in clashes on Tuesday night, leading to some Spaniards being detained, and on Wednesday afternoon.
The atmosphere in the city centre was tense in the hours before the game, with police and officers in military clothing deployed to restore order after clashes in bars near the market square. There were 28 arrests made.
