Tell me about the football career of Adao
Carlos Manuel Pereira Pinto (born 3 April 1960), commonly known as Adao, is a Portuguese former footballer who played as a central midfielder.

Born in Chaves, Vila Real District, Adao started his career with hometown club G.D. Chaves, moving to the Primeira Liga in 1980 with Varzim SC. He appeared in only eight games in his first season, which ended in relegation, but helped with 27 and three goals to an immediate promotion.

In summer 1985, Adao joined Vitoria de Guimaraes. In his second year he played 30 matches as starter and scored twice – including once in 1–0 away win over S.C. Braga in the Minho derby – as his team finished in third position.

Adao signed with C.F. Os Belenenses for 1988–89. On 12 October 1988, in that campaign's UEFA Cup, he scored the game's only goal at home against Bayer 04 Leverkusen, as the Lisbon side ousted the title holders 2–0 on aggregate. Later in the season he also appeared in the final of the Portuguese Cup, won after beating S.L. Benfica.

Aged 30, Adao moved to F.C. Penafiel, spending his last three years (of five overall) in the second division. Over the course of 11 seasons, he amassed top-tier totals of 279 games and 16 goals.
