In the 2009 summer de Val moved to Real Madrid, being assigned to the C-team in Tercera División.[2] He appeared in 23 matches during his first season, and in further 20 in his second.
On 27 January 2012, after making no appearances in the campaign, de Val was loaned to fellow league team UE Olot until June.[3] He appeared sparingly before returning to the Blancos in the summer.
In July 2012 De Val joined Segunda División B's CD Olímpic de Xàtiva.[4] He made his debut for the club on 26 August, starting in a 0–0 away draw against CD Binissalem.[5]

On 24 June 2013 de Val moved abroad for the first time in his career, after agreeing to a two-year deal with English Football League Championship side Doncaster Rovers, managed by Paul Dickov.[7] Dickov had tried to sign him two years previously whilst managing Oldham Athletic but at that time the compensation fee was too much.[8]
