Arsenal and Cologne have been charged by Uefa after incidents during Thursday’s Europa League match at the Emirates.
The German club face four charges, including crowd disturbances and setting off fireworks, while the North Londoners face a lesser charge over blocked stairways.
The game was delayed by an hour as many thousands of away fans arrived at Emirates Stadium without tickets, causing security problems including a number of unruly attempting to rush the gates before kick-off in an attempt to gain entry.
Conservative estimates number Cologne fans in the ground at around 11,000 despite the German club being given a ticket allocation of 2,900.
The Islington Gazette talked to a supporter who said £17 tickets had been sold to Germans for more than £100.
This case is set to be heard by the Uefa Control, Ethics and Disciplinary Body on Thursday, September 21.
