The team will play in the Segunda División B in the 2018–19 season.

Cantera
Since 1912, Athletic Bilbao have employed a "cantera policy", which has come to be defined in an official (although not legally binding) signing policy whereby they will only recruit players with some link to the Basque Country. One of the main beneficiaries of the policy has been the Spain national team. Athletic has provided numerous players for it, second only to Real Madrid.
