Media sensationalism.
Real story is somebody sold a whole bunch of home tickets to away supporters. A lot. So a ton of Germans ended up in the home sections, which is pretty lucky for the club because when you looked at the home sections in general there were many. many empty seats. Seems that Arsenal fans stayed away in droves last night.
Meanwhile, two Jerries kicked over some railings, about 4 sour Krauts hit stewards with their handbags and a few pissed in the street. Otherwise, considering there was 20 thousand of them, there was nothing much untoward beyond extremely noisy and enthusiastic support.
Daily Mail has "Anarchy at Arsenal" sprawled across the back page
No anarchy, in fact considering so many away fans got into the home sections, somebody, somewhere behind the scenes did a good job of getting the game kicked off. Must have been an older, less hysterical figure who detected the fact we were dealing with a ton of loud Germans looking to take over the place - been there, seen it, dealt with it before. The Emirates Expects!
