I too live in a place which has a large black and asian population.
A very high proportion of these follow liverpool who are of a similar age to me.
One of the main reasons for them supporting them is to do with John Barnes , who was an iconic figure back them and they felt represented black people, and Nothing whatsoever to do with Liverpool being kings of Europe at the time.
Non of them however supported Watford, where Barnes was signed from,(for those that didn't know) or West Brom who had a fantastic team with many black players at the time.
Funny that?
