 By 1941, "la Blanquirroja's" star-studded squad was beginning to show its age.In the same year, Peru and Argentina played a three-game series for the Copa Roque Saenz Peña in Lima, and a struggling Peru managed to draw twice before finally losing the third match 3–0.The national squad's diminishing effectiveness was most apparent during the South American Championships of the 1940s, where the team's most positive performances came from goalkeeper José Soriano.
