Silas began working as a manager in 2007, and led Avaí in three spells, including their best Campeonato Brasileiro Série A finish of 6th in 2009.

[2] Silas played his last game for Sporting on 25 March 1990, scoring in a 2–1 loss to rivals Benfica in the Estádio da Luz.

He went to the 1986 FIFA World Cup in Mexico, where he made late substitute appearances in the last 16 win over Poland and the penalty shootout elimination by France in the quarter-finals.

[3][4] On 20 August 1989, Silas scored his only international goal in a 6–0 win over Venezuela in 1990 FIFA World Cup qualification at the Estádio do Morumbi.

[5][6] He led the newly promoted club from Santa Catarina to a best-ever sixth place in the 2009 Campeonato Brasileiro Série A.

[10] He was dismissed on 8 August after taking two wins from 13 games in that championship to leave the team in 18th; a goalless draw in the Grenal derby against Inter had saved his job a week earlier.

[15] In March 2012, he moved to Al-Gharafa in the same league, winning 4–1 on his debut the following day against Al Ahli with two goals by compatriot Diego Tardelli.

[16] Having son the Emir of Qatar Cup in the less than three months of his initial contract with the club from Al Rayyan, Silas signed a new one-year deal in June 2012.

[20] The following 10 February, he was dismissed after a defeat to Belo Horizonte rivals Cruzeiro left the club second-from-bottom in a season that they were aiming for the Campeonato Mineiro title.
