also provided players. In 1928, these four clubs became founding members of La Liga, demonstrating further the strength in depth of the Basque canteras at the time. The saying "Con cantera y afición, no hace falta importación", translated as "With home-grown teams and supporters, there is no need for imports", made sense during these early days. The ability of the Basque Country to produce great players was made clear during the early 1980s when La Real and Athletic won four Liga titles in a row between 1981 and 1984. The Real Sociedad team included, among others, Roberto López Ufarte, José Mari Bakero, Luis Arconada and Jesús María Zamora. Xabi Alonso, a World Cup winner in 2010, is also a product of Real Sociedad's youth system. Barcelona and Real Madrid Although Barcelona and Real Madrid are well known for regularly recruiting foreign players, both are renowned worldwide for producing local players. Along with Athletic Bilbao (see Bilbao Athletic), both clubs have notable reserve teams (Barcelona B and Real Madrid Castilla respectively) that are predominantly made up of Spanish players. Numerous senior players have graduated through the ranks of Barcelona's La Masia academy, including Francisco Carrasco, Ramón Calderé, Guillermo Amor, Albert Ferrer, Pep Guardiola, Sergi, Iván de la Peña, Francesc Arnau, Óscar, Roger, Gabri, Gerard, Luis García Sanz, Oleguer, Pepe Reina, Thiago Motta, Fernando Navarro, Xavi, Cesc Fàbregas, Carles Puyol, Víctor Valdés, Mikel Arteta, Andrés Iniesta, Bojan, Jeffrén, Lionel Messi, Giovani dos Santos, Gerard Piqué, Sergio Busquets, Pedro, Cristian Tello, Thiago, Rafinha, Marc Bartra, Gerard Deulofeu and Sergi Roberto, though some of these were recruited from overseas before signing professional terms, so are not "home-grown" in the traditional sense, if in the technical sense. Similarly, numerous notable professional players have graduated Real Madrid's youth academy, known as La Fábrica (the factory). In 1966, Madrid won the European Cup with a team of 11 Spanish players and a Spanish coach, marking the first time a home-born team had won the competition. Many great homegrown players have since passed through the ranks, among them La Quinta del Buitre — Emilio Butragueño, Manolo Sanchís, Martín Vazquéz, Míchel and Miguel Pardeza. Graduates of the cantera also include Iker Casillas, Álvaro Arbeloa, Esteban Granero, Raúl, Guti, Luis García Fernández, Juan Mata, Kiko Casilla, Borja Valero, Rubén de la Red, Dani Carvajal, Álvaro Negredo, Roberto Soldado, Rodrigo, Dani Parejo, José Callejón, Juanfran, Javi García, Álvaro Morata, Jesé and
