Born in Ferrol, Galicia, López graduated from Racing de Ferrol's youth system, and made his professional debut on 14 May 2005 when he came on as a late substitute in a 2–2 home draw against CD Tenerife for the Segunda División championship. In July he was loaned to lowly SD O Val, in Tercera División.
López returned to Racing in June 2006, and after appearing sparingly in the first part of the season (with his team now in Segunda División B), he cancelled his contract and joined Narón BP in the fourth level. In June 2009 he signed with Celta de Vigo, initially being assigned to the reserves in division three.
After scoring 13 goals with the B-team, López made his official debut with the main squad on 13 June 2010, playing 14 minutes in a 0–2 away loss to Real Sociedad. On 13 February 2013, he renewed his contract until 2018.
On 9 July 2015, López signed a contract extension with Celta until 2019, being immediately loaned to Sheffield Wednesday. Roughly one year later, still owned by the latter, he joined Real Valladolid.
