I think you're being ignorant. Cologne fans tore our stadium apart and stadium staff and security couldn't handle them can you image what angry Russians would do?
Hopefully Arsenal staff will have learned lessons and will beef up security for the home tie.
Heck, a Marseille fan stabbed a security guard in the neck in Bilbao yesterday. Hooliganism is real.
What? I was referring to the away leg, not the home leg.
