Steaming in by Colin Ward. Haven't read many about football in all honesty, and regrettably this book was the catalyst for a plethora of boasting bore-athons from Aquascutum clad goons from all corners of the country. Written towards the end of the 80's, it documents the author following his club Arsenal, England and Chelsea (his friends team) and is brutal, hilarious and fascinating in equal measure. He doesn't shy away from nor make any apology for the violence he was involved in, but throughout the book there are telling insights into what it means to be a working class football fan in England and what is written in the introduction is quite prophetic....
Also, I think it's called 'As long as you don't kiss me', A local journalists 20 year document covering Notts Forest during Brian Clough's tenure is well worth a read.
