The club played for two seasons in the Lancashire and Cheshire Amateur League, before turning professional and joining the Lancashire Combination becoming second division champions at the first attempt. They followed it up with a fourth place and runners up spot in the Central League. In an attempt to progress the club joined the Southern League. The club rejoined the Central League for the 1919–20 season and in 1921 became one of the founder members of the Football League's Third Division North. However the club resigned after two seasons, as it was felt that it could not attract enough support to justify a League side – in spite of the fact that average attendance of 5,480 in 1922 was almost 2,000 more than neighbouring Rochdale, who played in the same Division. The full Celtic story in the League is detailed in "Manchester A Football History" where Celtic are given the same level of analysis and research as the Manchester region's other sides.
