MK Dons are the worst club. Followed by Chelsea for Abramovich and generally treating their managers like ****. Arsenal - for all the reasons mentioned previously. I particularly hated their graceless fans after the FA Cup final, (found them far worse than the Sheff Utd fans after the semi-final tbh, although I did encounter a bunch of Blunts' neanderthals on the train heading to the match) Leeds, Millwall - they're the traditional clubs to hate. Don't have as much against Man U as many do, although they piss me off when playing at home midweek and I get caught up in all the match traffic when trying to get home. And like many I've developed hate for Crystal Palace over the last few years. My Dad always hated Coventry City due to altercations with one of their fans. He'd love what is happening to them now!
I won't bother with the big clubs because nobody likes them. Hate (In order) Coventry Forest Derby Dislike Plymouth Stoke Palace Spurs Whoever Ian Holloway is managing. Whoever Neil Warnock is managing.
I maintain a simple theory, everyone in red & white stripes as this includes Sheff Utd, Lincoln & Stoke.
