When I started that I thought it might be just him running on and off the pitch! Surely someone noticed in training that he wasn't a professional footballer ffs
Saw a thing on him where Le Tissier is talking about him (might be in that video linked haven't watched it) and he said that he turned up as a trialist in training, which happened all the time, he didn't think he was very good and thought that was it, then he was on the bench for the next game. Think he ended up playing for a team up north in the conference north, so he wasn't completely hopeless, obviously not PL level though.
