If I could offer my two cents from experience meeting the man.
Firstly, I thought he was a very good player, intelligent on the pitch and took up excelle t positions, hence the equaliser in 99.
However, having met him as a bright eyed 12 year old at a restaurant in London, where he was making an official appearance, I was left very disappointed in him as a person.
I queued up with everyone else to get an autograph and he asked me what my name was, I told him, and he just smirked and said 'what kind of a name is that,' and proceeded to laugh with his son who had brought with him.
My only conclusion form meeting him was he had a very high opinion of himself and that he evidently had bigoted views or some sort of prejudice towards people who looked different to him or had different names. And to do that to a kid is very low.
Obviously, that is a biased opinion on him as a person based on meeting him, and maybe that biases my opinion of h as a footballer, but I do think he was a very good player for us.
