Athletic Bilbao is a club that has remained faithful to its philosophy of competing without foreign stars and linked to a single region. This policy, which for many could be a burden, has not prevented the club from achieving 8 league titles and 25 Cups. The origin of this philosophy dates back to 1911, when the club was accused of lining up non-eligible players in the Cup. The controversy was enormous and had immediate consequences, leading the Federation to restrict participation to players from outside the state. At that time, Athletic decided to go further: Opted to sign only local players whose origins were easily verifiable. What began as a measure to avoid administrative conflicts eventually became a foundational principle that structured its entire history. In 1996, eligibility was expanded to Iparralde with the signing of Bixente Lizarazu, and in 2008 it was relaxed to include players who, without being born in the region, had been formed in it. This system is based on relying exclusively on a territory, although curiously this restriction does not apply to coaches or staff. By limiting its capture, Athletic reduces its market dramatically and is often forced to pay more to remain faithful to its policy. However, it explains that this weakness becomes a strength during sales. Athletic has no reason to sell its players at a low price, as replacing them is extremely complex. This firmness has been demonstrated in historic transfers such as Kepa Arrizabalaga to Chelsea for 80 million euros or Aymeric Laporte to Manchester City for 65 million. The Athletic system does not rely on money, but on an extremely dense network of over 180 associated clubs and the Lezama training center. There, the club does not seek players, but forms them itself. Unlike other teams that prefer established profiles, Athletic is forced to rely on its young players, not by choice, but by necessity, creating a virtuous circle where local talent knows it will have a real opportunity in the first team. As a club that belongs directly to its fans and not to an external owner, players are seen as people from the place: old classmates or neighbors.
