Paul Ellender (Football Conference, Football League, Football Conference North and Northern Premier league)?
Am I right?
I can think of a few who have played in three leagues but not four( I mean levels not branded sponsors of the leagues ie. I class Unibond and Dr Martins as the same). I also understand that the Conference North/South have only been around for 5 or 6 years but still its no mean feat!
Mickey Nuttell, Paul Bastock, Gareth Jellyman, Stuart Talbot, Chris Wright, Peter Costello, David Farrell are all examples of three leagues.
