In reality of course most United fans are "glory hunters" and soon, City will may not have the same amount but will have plenty. People from all over the world who watch the Premier League, usually support one of the best teams or the best team, that has been United, because first, people want to support their idols and secondly there games are shown more than any other teams. Then in England, it's the same, I grew up through an age of United dominance and despite being midland based, most people support United, simply because although we're in Midlands, still 30/40 mins from any Blues/Villa/WBA, so automatically, kids don't see teams very local, while plenty of the United supporting friends I have, their dads like football but aren't sort of die hard fans so as a kid when you watch TV and you have no one influencing who you should support and then you see Cantona, Giggs etc...your much more likely to look at them as idols and support that team rather than seeing Villa with Steve Stone and Alan Thompson in the midfield.
If City start to dominate around the English league and in Europe, the next generation, we'll see a helluva lot of City fans coming up.
Unfortunately, that's the world. Thankfully, I grew up with my Dad a big Villa fan who was willing to take me from a young age.
But like anything, Federer is my favourite tennis player because when I started watching tennis properly 5/6 years ago, he was so dominant, played so beautifully and won, it was just great to watch and even though his dominance is no more, I still support him because I did also for 5/6 years.
Barcelona, last year really it started, just the football they play drew me to them, I've barely missed a game of theirs since, especially this season, missed about 4 league games. I guess I'm a glory hunter but I just can't take my eyes off their football and really do love likes of Messi which makes me support the team.
United have an extremely large base of glory hunters, if they can't admit it then they are simply stupid but being a glory hunter is nothing to be ashamed of, well unless you are bought up a fan of a local team, taken to games and then at some point after the age of 12 (cut off point!) start supporting someone like United!
It's just logical.
