English Premier League club Arsenal and Bundesliga outfit FC Cologne, have been charged by Europe’s football governing body UEFA following incidents during Thursday’s Europa League match.
According to bbc.com, FC Cologne face four charges, including crowd disturbances and setting off fireworks, while Arsenal face a charge over blocked stairways.
The game was delayed by more than an hour as thousands of FC Cologne fans arrived at Emirates Stadium without tickets.

The case is expected to be dealt with by the UEFA Control, Ethics and Disciplinary Body on 21 September.
