Real Sociedad de Futbol "B" (also known as Sanse) is a Spanish football team based in San Sebastian, in the autonomous community of Basque Country. Founded in 1955, it is the reserve team of Real Sociedad and plays in Segunda Division, holding home games at Campo Jose Luis Orbegozo holding 2,500 spectators of the Zubieta Facilities.
Unlike in nations such as England, 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 their senior team. Therefore, the team is ineligible for promotion to La Liga, the division in which the main side plays. Reserve teams are also no longer permitted to enter the Copa del Rey.
The team's origin dates from 1952 when the Real Sociedad youth team were runners-up in the Copa del Rey Juvenil and the club's board sought to bridge the gap between the talented teenagers and the senior team: the concept of Real Sociedad de Futbol Junior was introduced, but economic problems delayed its first official match until 1955, immediately after the youth team won the Copa Juvenil.
