[1] When Knighton signed the 5' tall Hugh "Midget" Moffatt from Workington in 1923, Norris was furious when he found out; he overruled his manager and promptly sold the player to Luton Town before he'd played a League game.
[2] During his final season at Arsenal, Knighton was involved in one of the first recorded cases of doping; before a January 1925 FA Cup first round tie against West Ham United, Knighton gave the players what he described as "little silver pills", given to him by a Harley Street doctor who was a fan of the club; although the pills were successful in increasing the players' energy, the side-effects caused them to have raging thirst.
[5] Norris denied this and instead cited Arsenal's poor record that season (having finished 20th and knocked out of the FA Cup first round), but later regretted his dismissal, stating it was the one mistake in his career[6] and in his will left Knighton £100.
After leaving the Gunners, Knighton went on to manage Bournemouth & Boscombe Athletic (1925–28), Birmingham (1928–33), whom he led to the 1931 FA Cup Final, Chelsea (1933–39) taking over from the long serving David Calderhead, and Shrewsbury Town (1945–48), before their election to the Football League.
Knighton retired to Bournemouth after suffering ill health and took on the less pressurised job of a golf club secretary, during which he found time to write an autobiography, Behind the Scenes in Big Football (1948).
