Athletic Bilbao
The club is known for its "cantera" policy of bringing young Basque players through the ranks, as well as recruiting players from other Basque clubs like Joseba Etxeberria and Javi Martínez. Athletic's official policy is signing professional players native to or trained in football in the greater Basque Country, which includes Biscay, Gipuzkoa, Álava and Navarre (in Spain); and Labourd, Soule and Lower Navarre (in France). Since 1912, Athletic has played exclusively with players meeting its own criteria to be deemed as Basque, and has been one of the most successful teams in La Liga. This can be seen as a unique case in European football; it has gained Athletic both admirers and critics. The club has been praised for promoting home grown players and club loyalty. The Basque rule does not apply to coaching staff however, with several examples of non-Basque managers both from Spain and abroad having coached the first team.
