Bath born wing half Charlie Slade joined hometown club Bath City in 1910 before moving to Stourbridge in 1912 from where he joined Aston Villa, making his Football League debut at Sunderland in September 1913 and playing 3 times for their first eleven before moving to Huddersfield Town in March 1914. His Huddersfield career was interrupted by the First World War but in 1919 he returned to Leeds Road helping them to promotion from the Second Division as runners up in 1919-20. He was a member of their 1922 FA Cup winning team that beat Preston North End 1-0 in the Final at Stamford Bridge, also playing as they beat Champions Liverpool in the Charity Shield a month later, but the following season he joined Middlesbrough in October after 7 goals in 130 appearances for Huddersfield. He had 3 seasons at Middlesbrough scoring twice in 70 appearances before joining Darlington in the summer of 1925, for whom he made 24 appearances before joining non league Folkestone in 1927.
Slade was working as a scout for Crystal Palace when manager Ronnie Rooke resigned in November 1950 and Palace appointed Slade as joint-manager with long-serving player, and Rooke’s assistant, Fred Dawes. However the club had a poor 1950-51 season and in October of the next campaign Dawes and Slade were removed from their positions. Slade reverted to his position as a scout and remained with Palace until 1955.
