马来西亚 23岁以下

The team is considered to be the feeder team for the Malaysia national football team. It is for players aged 23 and less, however 3 senior players can also be selected to play. Also in existence are national teams for the Under-20s, Under-17s and Under-15s. As long as they are eligible, players can play at any level, hence it is possible for one to play for the U-23s, senior side and then again for the U-23s.

Olympic 2000

After the 1997 FIFA World Youth Championship, FAM was aiming to qualify for the 2000 Sydney Olympic. Thus, the FAM spent about US$6 million and continued the contract of Malaysian youth team coach, Hatem Souissi. Then FAM formed a squad known as Olympic 2000 with a combination of 1997 youth squad and other under 23 players. FAM decided to include Olympic 2000 as one of the teams in Malaysia League. Their first match was against Johor FA in a qualification match for Malaysia Premier I League. The team won their first match away 1–0 before drawing 1–1 at home to qualify for Malaysia Premier I League. However the team finished bottom during the 1998 season with only 4 wins in 22 matches. The Olympic 2000 also showed poor performance at the international stage. They were humiliated by the Thailand Asian Games squad in a 1998 friendly match as the Thais beat them 9–0. During the qualification matches, Olympic 2000 only managed to finish third behind Hong Kong and Japan. It was questioned among fans how a squad that had been playing together since 1995 with fine talents and given so much exposure cannot achieve expectations.

Disbandment of Harimau Muda

After Harimau Muda project disbanded, FAM needed a fresh start for the U-23 team where a new set of players was brought in for the team with the creation of SEA Games Project 2017 team. The players in the team mainly consisted of players with ages around 18 to 21 years old where the oldest players will be below the age requirement of 22 years old when 2017 SEA Games in Malaysia started. With a bigger pool of players within age of 18–22, the players in the team will also play in other age-restricted tournament as the younger side such as U-21 and U-22 when needed.
