History of Athletic Bilbao
Meanwhile, sons of the Basque educated classes had made the opposite journey and went to Britain to complete their studies in civil engineering and commerce. While in the United Kingdom, these students developed an interest in football and on their return to Bilbao they began to arrange games with British workers. In 1898, students belonging to the Gymnasium Zamacois founded the "Athletic Club", using the English spelling. In 1901, a meeting was held in the Café García, which established more formal rules and regulations. In 1902, the two Bilbao clubs formed a combined team, known as "Bizcaya", in the first Copa del Rey. They returned with the trophy after defeating Barcelona in the final. This would lead to the eventual merger of the two clubs as "Athletic Club" in 1903. In the same year, Basque students also formed "Athletic Club Madrid"; this club later evolved into Atlético Madrid. The club's foundation date is a subject of debate among football historians. The club itself declares 1898, but others claim 1901 or 1903 as the true founding year.
Athletic Bilbao cantera
The core of boys from the local Biscay region are first introduced into the Lezama "Alevín" teams at around 10 years of age and advance by an age group every season through "Infantil", "Cadete" and "Juvenil" levels. The players who are retained by Athletic after their Juvenil A spell (aged about 17) typically join farm team CD Basconia in Basauri, with the squad normally expanded further with signings from the regions’s youth clubs, most notably Danok Bat and Antiguoko who regularly challenge the professional academy teams for the title in their División de Honor group. A number of senior players have also emerged from the Txantrea club in Pamplona who have a collaborative agreement with Athletic (renewed for four more years in 2017).
The players usually spend one or two seasons at Basconia before the best are promoted to the reserve team Bilbao Athletic and then on to the senior team when considered ready to do so. There are exceptions to this sequence; notably Iker Muniain showed such promise that he was promoted early to "Juvenil A" as a 15-year-old in 2008, was selected by Bilbao Athletic as soon as he turned 16 in January 2009 and became a senior team regular at the start of the next season.
