The
Football Association of Singapore announced on 2 July 2025 on the new Singapore Premier League 2. The league aims to ensure Singaporean players continue to get sufficient playing time, and was introduced to replace the SPL under-21 competition. The league will establish a clear link between development and first-team football, with squads integrated across both competitions. This structure aligns both club needs and national development goals by expanding the base of competitive opportunities while keeping quality and progression at the forefront. Clubs must register a combined squad for both the
SPL and SPL2, with a minimum of 36 and a maximum of 50 players. At least 25 of them must be Singaporeans. First-team players and foreigners are allowed to play in the league to ensure they get sufficient playing time, of which a minimum of six locals, four of whom must be under-23, must be on the pitch at all times during matches. In addition, senior players can also participate where it is appropriate helping them to regain fitness or form. SPL2 matches will take place between Mondays and Wednesdays, while SPL fixtures will be played from Fridays to Mondays. ==Clubs==
