AJ Auxerre
Sissoko played as a striker in the youth system of French club AJ Auxerre.

Valencia
In 2003 Sissoko made a free transfer to Spanish club Valencia CF, managed by Rafael Benítez. 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. In his second season at the Estadio Mestalla, Sissoko played 21 matches in La Liga and also appeared in the UEFA Champions League.

Liverpool
Sissoko moved from Valencia to Liverpool for £5.6 million in the summer of 2005. His first appearance was against Kaunas on 26 July 2005. In the summer of 2007, Sissoko rejected offers from Barcelona, CSKA Moskava and Juventus to stay at Merseyside.

Juventus
In January 2008 Sissoko transferred to Italian club Juventus, where he would team up with former coach Claudio Ranieri, for a fee of €11 million. He made his first appearance for the club in February 2008, coming in as a 67th minute substitution for Tiago in a Serie A fixture versus Cagliari Calcio. Sissoko scored his first goal for Juventus on 2 March 2008, the equaliser against Fiorentina. During the first half of the 2008–09 season, he regularly featured in the starting line-up, forming a partnership with youngster Claudio Marchisio as the centre midfield pair in Claudio Ranieri's 4–4–2 formation. His 2008–09 season ended early after he broke his foot in March 2009 ruling him out for the rest of that season and into the start of the 2009-10 season.

In April 2012 Sissoko captained the squad against rivals Olympique de Marseille in Le Classique, but was sent off in the 86th minute for two bookable offences in a game that finished 2–1 to the Parisian club.
