Arsenal have issued a warning to Cologne fans ahead of their Europa League tie on Thursday.
The German outfit are known for their passionate support and will arrive in numbers ahead of their visit to The Emirates.
Arsenal have informed supporters of the German side that they will be ejected from the stadium should they be found in the home end or cause any trouble.
Cologne, who are back in European competition for the first time in 25 years have sold out there 3,000 tickets for Thursday’s clash, but reports suggest they could bring as many as 20,000 to North London.
Arsene Wenger’s side have made steps in an attempt to ensure there is no trouble around the ground before and after the game.
The Frenchman is expected to play a weakened team with Sunday’s meeting with Chelsea in mind.
Arsenal fans have taken to Twitter and are excited about Thursday’s potentially raucous atmosphere…
I hope London will be the same on Friday after all the Dortmund and Cologne fans have left the town. It's gonna be tough week for Londoners

Sounds like there's going to be more Cologne/Koln than Arsenal fans at the Emirates on Thursday for their massive Europa League clash
We're playing a team who care, could mean trouble.

Almost certainly I'd say. I'm disappointed I can't make that game. Playing against German teams always makes for a great atmosphere
