The final category within the youth structure is the Juvenil A under-18/19 team which represents the club in the top national competition.

The successful graduates then usually move to the club's reserve team, Sporting de Gijón B which is also considered part of the cantera due to being a stage in progression towards the senior team, albeit competing in the adult league system.

The top football clubs in the Spanish leagues generally place great importance in developing their cantera to promote the players from within or sell to other clubs as a source of revenue, and Sporting de Gijón is no exception.

International players such as Luis Enrique, Abelardo, Javier Manjarín and David Villa learned their skills at Mareo.
