Carlos Manuel Oliveiros da Silva (born 9 March 1959 in São João da Madeira), known as Vermelhinho, is a retired Portuguese footballer who played as a left winger.
After beginning professionally with two lowly clubs, including local A.D. Sanjoanense, Vermelhinho signed for FC Porto at the age of 23, in 1982. In the 1983–84 European Cup Winners' Cup he scored arguably his most important career goal, as his team won 1–0 at Aberdeen (2–0 aggregate): in a foggy night, he netted through an amazing long-range lob, and went on to also play the entire final, lost 1–2 to Juventus FC.
Vermelhinho closed out his career at first club Sanjoanense at the age of 36, also having represented in one-season spells G.D. Chaves, S.C. Braga and S.C. Espinho. For Portugal he earned two caps, being picked for the squad at UEFA Euro 1984, where he did not leave the bench.
