The Peru national team enjoyed its most successful periods thanks to footballing generations from the 1930s and the 1970s. The 1930s generation led Peru at the inaugural FIFA World Cup in 1930 and won the 1938 Bolivarian Games and the 1939 Copa América, with goalkeeper Juan Valdivieso and forwards Teodoro Fernández and Alejandro Villanueva playing important roles. The 1970s generation qualified Peru for three World Cups and won the Copa América in 1975; the team then notably included defender Héctor Chumpitaz and the forward partnership of Hugo Sotil and Teófilo Cubillas, often regarded as Peru's greatest player.
