The Singapore Premier League is Singapore's only professional football league. It comprises eight teams with extreme variance in financial resources, with the top two qualifying for the second-tier continental club competition ACL2 (in addition to playing in the SPL). In 2023, the SPL limited teams to fielding 4 foreign players at any one time in matches. This was increased to 6 in 2024-25, and 7 for the 2025-26 season. There are no maximum foreign player limits in continental competition.
In the 2024-25 season, the Lion City Sailors became the first Singapore club in history to reach the final of the ACL2, starting 7 foreign players in the final. Singapore clubs do not currently qualify for the top-tier continental club competition ACL Elite, and will need to repeatedly achieve similar results in the next few years to qualify for the top-tier.
The Singapore national team comprises Singaporean players who play in SPL clubs and overseas leagues. It only competes against other national teams.
