Never known United or Liverpool to do a Soccer School in a school in a South Wales. I’ll stand corrected if someone can put me right.
As for the other thing, the lad in question was a motivating figure for galvanising the Merthyr support in saving their club. He continued to play a role after that lending his knowledge and skills for nothing in addition to paying his monies into the club.
I’m not sure if that makes him a supporter or not?
