2015 FA WSL
The 2015 season of the Women's Super League was the fifth season of the FA WSL, the top-level women's football league of England. The season was played from 25 March to 4 October.
Liverpool were the defending champions from the 2014 FA WSL. Chelsea became the title winners and together with Manchester City qualified for the 2016–17 UEFA Women's Champions League.
This was the second season since the WSL 2 was introduced. As part of a two-year expansion plan, the WSL 1 will increase to nine teams for the 2016 season. By the end of the 2015 season two teams were promoted from WSL 2 to WSL 1 and only one team relegated to WSL 2, with one team being promoted from Premier League to WSL 2.
Background
In December 2014, the FA WSL announced a two-year plan to expand WSL 1 from an eight to 10-team league. Two teams will be promoted from WSL 2, while one team will be relegated to WSL 2. Also, for the first time, a team from the FA Women's Premier League earned promotion to WSL 2, effectively connecting the WSL to the rest of the English women's football pyramid.This will leave WSL 1 with nine teams and WSL 2 with 10 teams for the 2016 season, and with the process repeated the following year, both WSL 1 and WSL 2 will have 10 teams each for the 2017 season.
