William Johnstone (18 May 1901 – 1975)[1] was a Scottish footballer who played as an inside forward or centre forward.
His clubs included King's Park and Clyde (two spells) in Scotland, and Reading, Arsenal and Oldham Athletic in England.
[2][3] While at Clyde, he was selected for the Glasgow FA's annual challenge match against Sheffield in September 1926, scoring twice,[4] and moved to Reading a few weeks later.
[5] In his first season with the Royals, he had a prominent role in the club's run to the FA Cup semi-final in 1926–27,[6][7] and scored the winning goal in a giant-killing victory over reigning English champions Sheffield Wednesday in the same competition two years later.
[8][9] Signed by Arsenal in summer 1929, technically he was a member of the Gunners' squad that won the Football League title in 1930–31, but he made only two appearances in that campaign before moving on to second-level Oldham mid-season, having failed in his efforts to break into what was a very strong attacking line-up at Highbury.
