Born in Vitoria-Gasteiz, Álava, Vélez began his career in the lower leagues, playing for local CD Aurrerá de Vitoria and RCD Espanyol's B team.
[2] He made his debut in the competition as a late substitute in a 2–0 away loss against Villarreal CF on 23 September 2007,[3][4] netting two months later in the 1–1 draw at RCD Mallorca.
[5] The following season, Vélez joined Athletic Bilbao,[6] but took almost no part whatsoever in the Basque side's campaign (only five competitive matches).
[7] His contract was mutually terminated in late July 2009, and he joined relegated CD Numancia on a three-year deal, with the former club being able to re-buy in 2010 or 2011 – Athletic teammate Joseba Garmendia also made the move.
[18] On 16 June 2023, having been unable to prevent the Galicians' relegation, Vélez signed as new coach of SD Ponferradina, who also went down to Primera Federación.
