Waldir Cardoso Lebrêgo, best known as Quarentinha (Brazilian Portuguese: [kwɐɾenˈtʃĩ j̃ɐ]; born in Belém, Pará State, 15 September 1933 – died in Rio de Janeiro, 11 February 1996) was a Brazilian football (soccer) player who played as a forward who and was notable for his fearsome left foot.
He won four Bahia State League (1953, 1957, 1964, 1965), three Rio de Janeiro State League (1957, 1961, 1962), two Rio - São Paulo Cup (1962, 1964), one Mexico Tournament (1962) and one Paris Tournament (1963). He was also the top goalscorer for three consecutive years in Rio Leagues (1958, 1959, 1960).
Quarentinha won 11 international caps for the Brazil national football team between 1960 to 1963, scoring 11 goals. No-one in the history of Brazilian football has a better goal average (one goal per game). Quarentinha also played six friendly games for Brazil in which he scored six additional goals. His greatest regret was to be left out of the Brazilian squad that defended the World Championship crown in Chile in 1962. On 12 May 1963 he was in the squad at San Siro Stadium, in a match against Italy, Pelé's only game played in Italy. He never played in FIFA World Cup and died at 62.
