Francisco Ferreira de Aguiar (11 November 1930 – 22 May 2012), known as Chico Formiga or simply Formiga, was a Brazilian footballer and manager. Mainly a central defender, he could also play as a defensive midfielder.
Born in Araxá, Minas Gerais, Formiga joined Santos' youth setup in May 1950, but made his first team debut in the month after being promoted to the main squad by manager Artigas.[1]
Formiga became a starter at Peixe in the 1952 season, winning the Campeonato Paulista twice for the club in 1955 and 1956. In the start of the 1957 season, he moved to Palmeiras for a fee of ₢$2 million plus the transfers of Laércio and Jair Rosa Pinto.[1]
Formiga returned to Santos in 1959, taking part of the Os Santásticos squad that won two Copa Libertadores and two Intercontinental Cups. He retired in December 1962, after playing 410 matches and scoring twice for the club during his two spells.[1]
Shortly after retiring, Formiga remained at Santos to work in the club's youth categories. He took over the first team for the first time in 1978, winning the year's Paulistão, which ended only in 1979.[1]
In 2001, after being in charge of Palestra de São Bernardo in the previous campaign, Formiga returned to Peixe as a youth football coordinator.[5] He left the club after a change in the organization chart.
