In reply to FesteringSore:
Just sounds like a typical but high level football supporter to me.
A lot of them in my experience do nothing except watch football (or general sports but mainly football and rugby) and have little to no interest in anything outside of that world.
They seem to get totally indoctrinated in to following their chosen sport as though it is a religion as deep as a radicalised Muslim with their faith but fortunately without the prevalence of suicide bombing.
Working out on site I come across a disturbing amount of people who live this life.
