In 2003 Sissoko made a free transfer to Spanish club Valencia CF, managed by Rafael Benítez, where he was deployed in midfield. Valencia won the 2003–04 La Liga title and in the same year became UEFA Cup champions, during which Sissoko played nine matches. The following year, Benítez left to manage Liverpool and was replaced by Claudio Ranieri.
