In How Soccer Explains the World by Franklin Foer

In How Soccer Explains the World by Franklin Foer, Foer takes a story telling approach to explaining how soccer has contributed to globalization. So far I have read about how the fans of Serbia's most successful team, Red Star Belgrade, interact and intimidate opposing fans. These Serbs call themselves the Ultra Bad Boys and find themselves completely justified because they have "no use of firearms and no beating of the enemy after he loses consciousness." This, however, is not limited to just Serbia, violence is in integral part of the soccer culture.
