Humberto Dionisio Maschio (Italian pronunciation: [ˈmaskjo]; 20 February 1933 – 20 August 2024) was an Argentine-Italian football player and manager who played as a forward or midfielder.

[3][4][1] Maschio started playing at Arsenal de Llavallol to later move to Quilmes Atlético Club where he proved himself a prolific goal-scorer.

[5] 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.

[6][7] 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.

Following Maschio's move to Italy, along with his compatriots Sívori and Angelillo, the trio were banned from playing for the Argentina national team by the Argentine Football Federation, and missed out on the 1958 World Cup.
