The unrest occurred ahead of kickoff in a game between Aston Villa and Legia Warsaw. On Friday, Aston Villa said they had lodged a complaint with UEFA over the conduct of Legia Warsaw and the behaviour of the club's supporters. Legia Warsaw initially claimed that Villa had given them a lower allocation of tickets than they were entitled to under UEFA regulations. "Due to the inability to authenticate and distribute tickets effectively, Legia Warsaw returned the tickets to the host club," Legia Warsaw said in a statement on Saturday. Therefore, we strongly object to Legia Warsaw being blamed for Thursday's incidents in Birmingham."
