Born in Palmela, Setúbal District, Machado was a leading player for Vitória de Setúbal and FC Porto during the 1970s, winning two Primeira Liga titles with the latter even though he missed the entire 1978–79 due to injury. Over the course of 15 top division seasons, he amassed totals of 307 games and 25 goals; with the latter side, he was also involved in an internal dispute which resulted in the departure of 15 players, along with manager José Maria Pedroto and director of football Jorge Nuno Pinto da Costa.
After retiring at the age of 35 with his first club, Machado went on to become an assistant manager to Artur Jorge, joining his Porto staff in the 1984–85 campaign. There, he won two leagues in a row and the 1987 European Cup, remaining alongside Jorge into the 1990s when he finally became a head coach, managing both Porto and Sporting Clube de Portugal.
