Mario Rivas

Mario Rivas came through the academies of Atlético Madrid and Getafe before senior football took him to CD Móstoles URJC, where he made his debut in September 2019 and needed over a year to open his account, scoring against CD Leganés B in November 2020. From there the path ran through Leganés B, where 43 appearances and 9 goals earned him a single first-team outing for the club in the Segunda División, coming on as a substitute against UD Almería. Spells at Alcorcón, Lleida Esportiu, Navalcarnero and Real Ávila followed, mostly on free transfers — at Real Ávila he scored 12 goals in 31 appearances.

That form carried him to Felgueiras 1932 in July 2025, and his first season in Portugal has been his best yet: 10 goals in 33 Liga Portugal 2 appearances made him the club's top scorer. Among the highlights was a brace away at Oliveirense in May 2026, in a match Felgueiras won 5–1.

Rivas stands 191 cm tall and, despite Transfermarkt listing his preferred foot as right, is in fact ambidextrous. He has a twin brother, Óscar, who is also a professional footballer.
