A (Spurs fan) friend of mine often opines that Spurs and Arsenal fans aren't really that different, we just wear different coloured shirts.
Basically true. I think there is a bit of a mentality difference which reflects the histories of the clubs. I think we've always seen ourselves as the grammar school boys with Spurs being the unruly comprehensive school down the road, but there's a fair bit of similarity.
Serious question though. Would you rather be an Arsenal fan or a Spurs fan right now - and obviously I mean that if you were a nuetral who had to chose one club or the other which would you choose? I know who I would go for and its not the team with a c*nt as a manager.
