We had some of the worst managerial appointments in the history of the game, especially in the 80s and 90s.
Alan Ball, Frank Clarke, Phil Neale, Mel Machin, John Benson etc, but I would put Stuart Pearce right at the top of the list.
He had me hate going to my clubs game, he made me question why I liked football, the man was a wonderful player, but as a manager/coach he is a joke, the man has many issues and ANYONE who puts a kid's toy on the touchline and tells the world publicly about it should not be in the game.
