Real Sociedad de Fútbol B (also known as Sanse) is a Spanish football team based in San Sebastián, in the autonomous community of Basque Country. Founded in 1951, it is the reserve team of Real Sociedad and plays in Segunda División B, holding home games at Campo José Luis Orbegozo of the Zubieta Facilities. Unlike in 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.
