The following season, 1913–14, Charles made 31 league appearances and scored seven goals.[4]

A quarter-century of league appearances followed in 1922–23, Blackpool's final season under the guidance of Norman. Charles scored three goals, all in victories (one a single-goal result against Manchester United at Bloomfield Road on 31 March).[10]
Frank Buckley was installed as manager for the 1923–24 campaign, and he selected Charles on only six occasions in the league. He managed to score one goal, however, in a 1–1 draw at home to Stoke City on 15 September.
