On 3 December 2011 Cuenca netted his second league goal, playing the entire 5-0 home routing of Levante UD. On 31 January 2013, he was loaned to Eredivisie side AFC Ajax until the end of the campaign. Cuenca made his debut for his new team 10 February 2013, against Roda JC Kerkrade at the Amsterdam Arena, assisting Daley Blind in his first ever goal for Ajax as the match ended in a 1-1 draw.
