Cologne have been fined £53,000 by Uefa following fan trouble during their match against Arsenal in the Europa League.
Kick-off was delayed by an hour after thousands of ticketless Cologne supporters arrived at Arsenal’s Emirates Stadium for the match in September.
About 20,000 Cologne fans arrived in London, despite a ticket allocation of only 2,900.
The German club were issued with four charges by Uefa, including crowd disturbances and the setting off of fireworks.
They have been banned from selling tickets for one European away match, though that is suspended for two years.
