The
Singapore Premier League, formerly known as the S.League, was introduced in 1996 to replace the semi-professional
FAS Premier League. It is the first professional football tournament in Singapore. The
Prime League was introduced in 1997 for reserve teams of the Premier Division. After the professional league, the
Singapore Football League (SFL) was played for clubs associated with the
FAS. It made up the next tier and included two divisions. The SFL qualification tournament, Singapore Island Wide League or the IWL, is the next tier for newly registered
Football Association of Singapore clubs. In 2018, the Prime League was dissolved, making the then-called NFL the next tier. Outside the FAS leagues, the most competitive are the high level amateur tournaments known as the Cosmopolitan Football League, or the Cosmoleague, and the Equatorial Football League, locally known as the EFL. These leagues consist of mainly expat players and its members are known to have beaten the SFL and IWL clubs in pre-season friendlies. However, clubs from these leagues do not gain entry to SFL or IWL as the leagues are not organised by the FAS. == Current system ==
