Born in Lisbon, Yago played for four clubs during his youth career, starting with hometown's S.L. Benfica at the age of nine, then successively representing Sporting Clube de Portugal, Real Madrid and Valencia CF. As a senior, his first spell was with the Che's reserve team in Segunda División B, in a relegation-ending season.
Subsequently Yago continued in Spain, playing two years for RCD Espanyol B, helping the Catalans promote from Tercera División and being relegated in his second season, the exact opposite of what had happened whilst he appeared for Valencia B; in January 2010 he returned to his country for an unassuming loan spell with Gil Vicente FC, in the second level (no appearances whatsoever).
In July 2010, after not having his contract renewed by Espanyol, Yago was taken on trial by Swedish club Malmö FF, which had just lost Jasmin Sudić with a ruptured cruciate ligament. He played against Fulham in a 0–0 friendly draw, and his performance earned him a contract for the rest of the year, with the deal being confirmed by manager Roland Nilsson.
In August 2012, following a five-month spell with Girona FC in Segunda División, during which he scored in a 5–3 home win against Xerez CD, Yago agreed to a three-year contract with AEK Athens FC.
