Humberto Dionisio Maschio (; born 20 February 1933) is an Italian-Argentine former football player and manager who played as a forward or midfielder. At international level, he represented both the Argentina national team, winning the 1957 Copa América, and the Italy national team, taking part in the 1962 FIFA World Cup. Club career Maschio started playing at Arsenal de Llavallol to later move to Quilmes Atlético Club where he proved himself a prolific goal-scorer. He joined Racing Club in 1954 and was part of the Argentina national team that won the 1957 South American Championship. That team, and its forward line in particular, was nicknamed The Angels with Dirty Faces (a reference to the then-celebrated Angels with Dirty Faces movie) due to both their irreverent style of play as well as to their less than rigorous attitude to training. The nickname followed Maschio when he, along with fellow national team forwards Antonio Valentín Angelillo and Omar Sívori, moved from Argentina to play football in Italy after the tournament. There, the trio was also known as The Trio of Death due to their clinical ability in scoring goals. Maschio had originally been linked with a move to Juventus in 1956, but their interest cooled following the international between Italy and Argentina in Buenos Aires that year when he looked ineffective. Instead he signed for Bologna in 1957, but although he paired up with Bernard Vukas there, he was unable to recreate the form he showed at Racing. From Bologna Maschio moved to Atalanta, who bought a half-share in him during the 1959–60 season. In Bergamo Maschio regained the form that had taken him to international prominence scoring heavily, and creating numerous chances for his colleagues. At Atalanta Maschio moved from playing as central striker to a deeper role which allowed him to use his vision and creativity. So impressive was his form at Atalanta that he moved to Inter Milan in 1962. However, Maschio failed to fit in with manager Helenio Herrera who used him as a central striker and his time in Milan was of limited success. Following his time at Inter, Maschio briefly played with Fiorentina. His performance brought him to the Italian national team to play in the 1962 FIFA World Cup. He returned to Racing in 1966 to win the Copa Libertadores and the Intercontinental Cup in 1967. He finished his career with the Avellaneda side with
