Amílcar Barbuy made his debut for Corinthians at the end of the 1913 season, scoring in his first match. In 1916 he became the first Corinthians player to be capped by Brazil. He went on to make 19 international appearances, and was in the South American Championship winning sides of 1919 and 1922.
In 1918 Amilcar converted from a forward to centre half.
In 9 seasons with Corinthians he won 4 Campeonato Paulistas (1914,16,22 & 23).
When Amilcar parted company with Corinthians there was only one place for him to go- being from the Italian community he was already a member of Palestra Italia, and had actually played for them in their first ever match in 1914.
In 1931 Amilcar moved to Italy. He was player coach at Lazio, where the squad of 22 featured 10 Brazilians.
