Career
Born in Málaga, Andalusia, Rubén only played lower league football in his country. From 2007 to 2010 he competed in Segunda División Bachelor in representation of Real Valladolid B and Lucena CF, making no league appearances for the latter club in the last season. In the 2012 summer, after playing one year with Civil Defense Alhaurino in Tercera División and another with Juventud de Torremolinos CF in the regional championships, Rubén signed for Scottish First Division side Cowdenbeath, after his agent sent YouTube videos to manager Colin Cameron and the player impressed in a subsequent trial.
