If you enjoyed this book then I highly suggest Soccer Against the Enemy by Simon Kuper. This is the book that Foer modeled his book after. Some may even say he ripped it off.
If history is your thing then you must read The Ball is Round by David Goldblatt. Possibly the best sports book ever written.
Great book (written by a fellow Spurs supporter as well).
Other good books are Inverting the Pyramid (about tactics, formations, etc.), 'Ajax, the Dutch, The War' (about Ajax and Jews during WW2), Football Against the Enemy, The Glory Game by Hunter Davies (a great piece of football journalism—a must read), Futebol (about Brazil), Brilliant Orange (about Holland), and Sheilas, Wogs, and Poofters (which details the history of soccer in Australia).
