I'm a fool to let myself draw in this discussion, but nevertheless, here we go.
I never supported Celtic, never. I quite like Celtic, just like i love clubs like Palermo, Lille, Valenciennes and several English clubs amongst whom Arsenal (the horror, this is the ultimate proof that i'm not a real Spurs for people like you).
I consider myself more of a football fan than a fan of a club (here is the assist, come one score...that is what you like most of all...don't let this occasion in a million pass).
But nevertheless i also consider myself a fan of two clubs: Spurs and Racing Genk.
Am i a lifelong fan of those clubs ?
Racing Genk exists 25 years and i'm 52 years old...i used to be a fan of a club that doesn't exist anymore (in fact the signature that really sealed that clubs's fate, was that of my wife). So i had the luxury to be able to choose another club, but although i love Genk, it will never be like supporting that other club.
And now the big revelation. Since being a kid, i used to be a Man Utd fan. But in 1999 after the treble, i got fed up with the club (the ultimate reason: because they refused to play the FA Cup in order to play a WC for clubs in Brazil). And then for some reason i became a Spurs fan...i guess that makes me a glory hunter ???
End of discussion.
