Óscar Sielva

Born in Olot, Girona, Catalonia, Sielva was a product of local RCD Espanyol's youth system. He made his first-team (and La Liga) debut on 30 August 2008, at the age of 17 years and 24 days, in the season opener against Real Valladolid, coming on as a substitute for Iván de la Peña in the closing stages of the game and being booked in a 1–0 home win. He appeared in four more matches in that first campaign, before fracturing his clavicle twice. In late August 2009, Sielva was loaned to FC Cartagena, recently promoted to Segunda División. He appeared in only one sixth of the league games during the campaign, often clashing with manager Juan Ignacio Martínez who wanted to play him out of position as a winger; he returned to Espanyol in January 2010. Deemed surplus to requirements at his parent club, Sielva was also only reinstated with the reserves in January 2011. On 14 November, he joined Málaga CF's B team in a mutual agreement between both clubs. Sielva was released by Málaga at the end of 2012–13. He subsequently underwent trials at FC Barcelona B, Girona FC and Swansea City, with no success. On 17 June 2014, after one year out of football, Sielva signed for UE Olot in the Segunda División B. He continued to compete in divisions three and four in the following years, representing Marbella FC, CE Europa, UD Somozas, Rápido de Bouzas and SD Ponferradina. Sielva was an undisputed starter during his spell at the Estadio El Toralín, achieving promotion to the second tier in…

Sielva was a regular for the Spain under-17 side, playing a vital role in their victory in the 2008 UEFA European Championship held in Turkey.
