Humberto Carlos Cruz Silva (Spanish pronunciation: [umˈberto ˈkruθ], born 8 December 1939) was a Chilean footballer that played in two FIFA World Cups (1962, Chile third place, and 1966) as centre back, despite of his short height. He also has been a close friend of Pelé since they played against each other in the 1960s. According to Pelé, Cruz was one of his best markers and in several interviews he has mentioned the classic moment when Cruz pulled down his pants so he wouldn´t elude him. He is nicknamed as "Cheetah", because of his speed and agility.
