When I was in school, had to have a 'first division' team as well as Swans (who nobody dreamed would ever compete in that space, so two separate worlds really). So in those days of the early 70s it was all Arse, ManU, Livertool, Leeds or some strange kids that opted Chelsea. Leeds were my choice. Loved that team with Bremner, Hunter, Giles Jones, Lorimer, Clarke, Gray. Then I grew up and grew out of it.
I suppose some never do and 'support' these teams despite never having been near Anfield, Elland Rd or Old Trafford. It's like a 12 year old boy having a crush on Jenny Agutter (yep, guilty) but then never growing out of it. A bit sad and a bit pathetic.
