You're telling me mate, I'm exiled in Falkirk. Since they moved to the other side of town my local club is East Stirling FFS.
It's tough because there's so much money in London that clubs can get away with charging fortunes plus while there's a huge local rivalry it's more diffuse. I'm guessing that if you're from Darwen you're Blackburn, Nelson - Burnley and Leyland - Preston? Chorley - Bolton? Althought clubs in London are rooted in their local community they can draw support from all over, plus the commuter belt. Arsenal are less rooted in their local support, being a South London club in truth
