ABC have just shown a doco here in Oz, about Indonesian football. Lots of fan violence and corruption. Worth a look. ABC have iView service, so hopefully link works in NZ.
Features Persija Jakarta fan group Jakmania, and culminates in Persija winning their first title in 17 years. I didn't know Jakarta has 30M people! The city goes a bit nuts.
Stadium scenes similar to what you get in South America. Some teams, their fans are banned from travelling. Often the away team is taken to the ground in Armed Personal Carriers!! Could have been interesting for the Newcastle boys, if they had had to play away.
Even when Jakmania visit Bali to play Bali United, which supposedly has the most chilled fans in Indonesia (perhaps related to Bali being mostly Hindu), their is crowd trouble. Bali United are losing and a rumour goes around the ground, that they are throwing the game!! Match has to be stopped for a time, as the home fans vent their anger.
