Maguire I've been to Union v Dresden which was very heavily policed. No alcohol at the game for fears of trouble but we did get a shout out over the tannoy which was nice.
35 degree heat and they hosed down the crowds on the terraces at half time which was pleasant although a little reminiscent of Schindler's List.
Dresden playing against any East German team, St Pauli or Dortmund will have a massive police presence. They're one of the best re support in Western Europe IMO and have a lot of the aggro that goes with that. They regularly get away bans from the German FA (and just turn up en masse in the home end) or home bans (and turn up outside the ground) pitch invasions, storming grounds, the lot.
