Unlike the English League, 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, also not being able (although it was possible in the past) to compete in the Copa del Rey.
In 1991 the team changed its denomination to Cristinenc-Espanyol, being renamed Real Club Deportivo Espanyol B three years later, while also gaining reserve team status for Español. It fluctuated between the fourth and the third levels in the following decades, the longest spell being five years, with a second position in the 2001–02 season; in its three visits to the playoffs, the Catalan outfit subsequently failed to promote.
In 2009–10 Espanyol B finished in 16th position, above the relegation zone. It dropped down a division, however, in the relegation playoffs.
