Born in
Setúbal, Silvino started his professional career with hometown's
Vitória de Setúbal in 1977. He moved to
Vitória de Guimarães after five years at the club. Silvino was signed by
Benfica for
1984–85, but did not appear once in that year's
Primeira Liga, barred by
Manuel Bento. After a loan to newly promoted
Aves in the
following campaign, he returned, going on to have an interesting battle for first-choice status with
Neno for several seasons and helping the team to win four league titles. Silvino played in the
European Cup finals in
1988 and
1990, having
captained the side in the latter. He rejoined Vitória Setúbal in 1994 upon leaving Benfica, then moved to
Porto for the
1995–96 season: despite not having to face competition from
Vítor Baía in his
second year (as Baía had left for
Barcelona) he featured rarely during his stint, and closed out his career at northern neighbours
Salgueiros, retiring in June 2000 aged 41. Subsequently, Louro began a career as a goalkeeping coach, successively at Porto,
Chelsea,
Inter Milan,
Real Madrid and
Manchester United, always under countryman
José Mourinho. Several of the goalkeepers he worked directly with (Baía,
Petr Čech and
Júlio César) went on to win the
Best Goalkeeper award, given by
UEFA. ==International career==
