On a cold, sunny October day on the outskirts of Copenhagen, Denmark, a group of men dressed in black gathers outside Brondby Stadium to shoot off a couple of rockets, raise their fists and shout about how the home team will soon beat — and beat up — the visiting archnemesis, FC Copenhagen.
Police are out in force, riot helmets at the ready. Brondby-Copenhagen matches have a history of leading to vandalism, arrests and general mayhem.
