The French midfielder has gone back to his homeland for the remainder of the season after struggling to make an impact at Upton Park due to persistent injury concerns
West Ham has confirmed midfielder Alou Diarra has joined Stade Rennais on loan for the remainder of the 2012-13 season.
The 31-year-old joined the Hammers in the summer from Marseille, but has found first-team opportunities limited to just five outings due to the excellent form of Mohamed Diame and persistent injury concerns.
The France international recently told L'Equipe recently of his desire to leave the club after making just one Premier League start all season: “Yes, I want to go. It's breaking point.
"With the current coach [Allardyce], it is impossible. There's no dialogue, no explanation. At West Ham, I wasted my time."
Rennes will be the sixth French club Diarra has played for during his time as a top-flight player, after having spells at Le Havre, Bastia, Lens, Lyon, Bordeaux and Marseille respectively.
