I really enjoyed this book. Much of the book contained perspectives, statistics, and conclusions that you just cant find elsewhere in soccer literature. The book's statistics on the underpayment of black players in the 80's in particular is fantastic. The books section on how the most successful "selling clubs" operate is awesome. Also, during the "game theory of penalty kicks" section I was unable to put the book down. Symanzski and Kuper bring in stories and statistics from media members and soccer pros that support or deny their data.
That being said, there are certain chapters of this book that draw conclusions that are either boring, or wrong. For instance, the chapter comparing the parity of the NFL and the EPL draws the conclusion that the NFL and EPL are relatively equal in parity(despite NFL having 12 champions since the EPLs conception and the EPL having 5 champions, and one team with more than half the titles). I had to really force myself through the chapter on which country is most crazed about soccer. I felt that the conclusion was only slightly interesting, and the methodology not interesting whatsoever.
This book is certainly unique, and you can get perspectives that aren't really available elsewhere. I'd reccomend this book if your a big fan of soccer, but if you are just a casual, this book probably doesn't have too much to offer you.
