 Thanks to the goals of "Cachito" Ramírez, the squad tied Argentina at a game popularly known as "La Bombonera" (in reference to the Estadio Alberto J. Armando where the game was played).The squad, managed by "Didi" Pereira, followed a 4–2–4 formation that typically comprised José Fernández, Orlando de la Torre, Héctor Chumpitaz, and Nicolás Fuentes as the defenders; Ramón Mifflin and Roberto Challe as the midfielders; Julio Baylón, Pedro Pablo León, Teófilo Cubillas, and Alberto Gallardo as the forwards; and Luis Rubiños as the goalkeeper.The participation of Peru in the 1970 FIFA World Cup was particularly memorable when the squad caused surprise as they advanced into the quarterfinals by defeating Bulgaria 3–2 and Morocco 3–0, and despite losing 3–1 to Germany.
