Mentioned in my piece on the Victoria Ground Hartlepool in the context of our game there against Gateshead as we were on the way out of the National League. Naturally referring to Snape; Fearn and McKnight!!
From Wiki: Shackleton became a sports journalist after retiring as a footballer. He had been an outspoken critic of the football establishment during his playing career, particularly so of the maximum wage rule. He used his nickname, The Clown Prince of Soccer, for his 1956 autobiography. One chapter of that book was "The Average Director's Knowledge of Football". It consisted of a single blank page. The book proved to be immensely popular, and ran into five editions within three months.
