They finished bottom of the 20-team division, three points adrift of safety, so had to apply for re-election to the league for the 1910–11 season.

Alex Watson stepped down as secretary-manager at the end of the season, to be succeeded by Bob McRoberts, who had played as a forward for the club for seven years, and who became their first full-time manager, with no secretarial duties.

Twenty-six players made at least one appearance in nationally organised first-team competition, and there were ten different goalscorers.

Forward Charlie Millington played in 36 of the 39 matches over the season, and half-back Albert Gardner appeared in one fewer.

Walter Freeman was leading scorer with 10 goals, all of which came in the league.
