High Quality Content by WIKIPEDIA articles! The Young Lions are an under-23 football team from Singapore. Most of the members of the squad are players from Singapore's national under-23 team. The team comes under the direct control of the Football Association of Singapore (FAS), but is managed as a football club and has competed in Singapore's top club competition the S.League since 2003. By entering the Young Lions in the S.League, the FAS hopes to expose young players to top-level competition, thus helping to prepare them for international tournaments such as the Southeast Asian Games. As such, the Young Lions are one of the few football clubs in the world which place an age restriction on team members while playing in a top-flight professional league. The Singaporean members of the Young Lions squad also represent the country at under-23 international tournaments.
