Segunda B

Aside from those teams relegated from La Liga, Spain's second division has also included the reserve teams of the country's top soccer clubs, known as B teams. These B teams allowed sides to nurture new talent at minimal cost, as well as to recycle older players. But reserve teams cannot play in the same division as their senior team, and are thus ineligible for promotion to La Liga. Reserve teams are also no longer permitted to enter the Spanish Cup. In short, there is often no incentive for a reserve side to do well.
