Let me kick off by saying: Great read!!
The book is by Franklin Foer, and in it, he makes an analisys on how the game itself can be seen as globalization and it's effects/results on many different cultures where it encounters corruption, racism, tribalism, nationalism and hooliganism. Don't be thrown off by all these "isms", he travelled the globe and met with many figures who give their own view and experience with the game and life. Among the topics, The Red Star Belgrade's supporters part in the Serbian nationalism is INSANE!! Berlusconi's and the Agnelli's influence over the Italian game and how Inter supporters cope with it... Chelsea's drastic change from working class to the posh style... The never ending corruption in the Brazilian league... Real Madrid x Barcelona's rivalry with focus during Franco's regime... And more including the USA, which he makes and ironic analisys in the end.
Definitely worth getting this!
