Jenas is even more of a mystery considering he's a complete vacuum of a man.Not when you consider Jermain Jenas, a significantly less famous and successful footballer, presents the one show.
Neville was part of the treble team, an England regular and also one of the leaders of that England player revolt. He was probably already pretty widely known before he retired tbf.
Also, I'm always surprised how little people who don't follow football actually know - even when it comes to England players. For example I bet most wouldn't have a clue who Luke Shaw is despite him being England's left back for like 5 years now.
