I think that it is impossible to pick one player out of the hundreds that played there many of which were top names at the time.How they would compare with todays superstars I am not sure
Johnny Haynes in about 1958 Our own Johnny McNicholl early 50s. to name just a couple of oldies but for sheer ability and entertainment Frank Worthington has to be in the list.
David Beckham and numerous Man Utd and Liverpool players when they were the top teams same with Arsenal and all other old Div 1 sides. to many to mention.
