I forgot to mention Roy Hodgson.
A staunch Disciple of the Charles Hughes FA coaching manual from the 1970's that set coaching at grassroots level in England to the dark ages, where the mantra was to get the ball in opposition penalty area as quick as possible in as less passes as you could.
Bobby Robson and Terry Venables the best English national coaches since Alf Ramsay both had a outward look on Football, modern and progressive and The old farts of The FA couldn't wait to get rid of them.
How the great Brian Clough was ignored by The FA for the England job shows how In the dark ages Football was in the 70's and 80's.
Clough, Paisley, Kendall the best English Coaches the last 50 years would never have been in the conversation at The FA for the England job, they were light years ahead in coaching and how the game should be played.
