In Britain, the club you support has nothing to do with how successful, or not, they are. It's based on tribe memory and geographic loyalty. If that didn't exist, there wouldn't be five professional leagues with Ninety two teams in England alone, Scotland, NI and Wales have their own setups. That's not including lower league semi professional clubs, all of which put arses in seats regularly to support them. I support my club because I was, a) born within the sound of the Great Bell of Bow, b) within a mile of their home stadium, and c) they have been my father's, his father's, and so on back to the club forming on the banks of the Thames in 1895. You don't choose your club so much as inherit it.
