Winning breeds a new sets of fans, which inturn will grow into supporter.
Those of you old people starts supporting united because of your parents, ask them why they support united? It's because of glory, and i dont mean title alone, but then romantism that comes with the club.
Maybe it's busby babes, maybe its attacking football, maybe for most of us the co92 and the romance between having beckham in your team, for some maybe it's many things, but they're all glory in their own ways. I started to like united because of beckham, back then i dont even know what united won, but i do get enthralled with the players and their history.
So unless you support teams like norwich, please refrain from calling others glory hunter. It's unsulting and a hollier than thou attitude.
