CD Aurrerá Ondarroa

Club Deportivo Aurrerá Ondarroa (Ondarroako Aurrera Kirol Elkartea in Basque) is a Spanish football team based in Ondarroa, in the autonomous community of Basque Country. Founded in 1921, it plays in, holding home matches at Zaldupe.

Development fee
In February 2018, the club received a €600,000 windfall resulting from the transfer of their former youth player Iñigo Martínez who moved between the region's biggest clubs Real Sociedad and Athletic Bilbao. Although less than 10% of the €32 million fee (the standard youth development payment percentage) due to a prior agreement between Aurrerá and Real in the event of a big move involving the player, it represented three times their annual budget and allowed for significant improvements to be made to facilities.
