Not sure if they've been mentioned here before but I've bought a couple books over the last couple weeks after finishing up Fever Pitch. Bought How Soccer Explains the World which appears to be an interesting book detailing how the game has caused clashes and coming together between civilizations, how it's affected economies, and everything else.
I also got The Miracle of Castel Di Sangro which is a book about a small ragtag club in a town of 5500 people in the mountainous region of Italy called Castel Di Sangro. Talks about their rise from Serie C2 in 1993 all the way to Serie B in 1996. They're currently below C2 again, but should be an interesting read and I've heard it talked up as a great book on a daily footy podcast I listen to while at work.
