Reserve teams in Spain play in the same football pyramid as their senior team, rather than a separate league. However, reserve teams cannot play in the same division as the main squad.
Reserve teams are also no longer permitted to enter the Copa del Rey. Additionally, only under-23 players or under-25 players with a professional contract can switch between senior and reserve teams.
History
Founded in 1942 as Triana Balompié and named after a working class district in Seville. Legend has it that Betis, later to evolve into Real Betis, was formed in 1913 by a group of Sevilla FC directors after the club refused to sign a player who came from Triana.
In 1976, the team was renamed as Betis Deportivo and started to compile an impressive record in the Spanish U-19 Cup, winning the competition in 1983, 1990, 1998 and 1999, and finishing as runners-up in 1969 and 1992. This record was only bettered by FC Barcelona, Real Madrid and Athletic Bilbao, and Betis were also runners-up in the U-19 league in 1990.
Betis Deportivo spent the vast majority of its existence in Segunda División B and Tercera División, never reaching the promotion playoffs in the former category.
After being named as Real Betis B between 1991 and 2017, the club recovered the name of Betis Deportivo.[3]
