it is one thing that never ever ceases to amaze me over here, how much away fans are seen as an absolutely integral part of any matchday. Even on our biggest "risk" matches (against Cologne, for eg) our beergarden at Gladbach (which really is a thing of wonder) is packed with fans, even Cologne ones (normal ones, not ultras) sharing a beer and a sausage and having a laugh at Schalke in the 2nd division on the big screen. all grounds allocate between 5 and 10% of the capacity to away fans - and when (it happens sometimes) away fans are not allowed, the home ultras ALWAYS have something to say about that, usually with a banner or two.
