Born in Barcelona, Catalonia, Olmo emerged through FC Barcelona's prolific youth ranks at La Masia, and first represented professionally its B-side. On 20 May 2006 he made his debut for the first team, playing the full 90 minutes in a 1–3 away loss against Athletic Bilbao as a number of the main squad's players were already resting for the 2006 FIFA World Cup and Barça were already league champions.
During the 2006–07 pre-season, Olmo took part in five games for the senior team, and added a second La Liga appearance, one minute at Getafe CF (1–1 draw). After a loan in the second division with lowly Racing de Ferrol, he was released by Barcelona and joined another club in that tier, Elche CF.
