Hungarian fans did not travel to London in an organized way for the England-Hungary World Cup qualifier, but the Hungarian camp clashed at Wembley. Allegedly with Polish help - the Polish flag visible in the recording also reveals this. It is not known why the situation became tense, but there is no question based on the recording that the members of the camp clashed with the security. And as if the security guards were not on top of the situation, they ran away from the fans' harshness.
Below is the video published in the Daily Mail.
