Therefore, the team is ineligible for promotion to the Malaysia Super League, the division in which their parent side competes in. Reserve teams are also no longer permitted to enter cup competitions other than the Malaysia Challenge Cup.

The team is officially known as Selangor U-23 on the club's official promotion and website, as the Malaysian Football League, the governing body of the top two divisions in the Malaysian football league system has rules that prohibits reserve teams from having different names than their parent team.
