The Senegalese striker was that desperate to leave the Hammers in the summer that he conducted a medical with Rennes without the club's permission.
His fortunes haven't changed much since then, having not started one Premier League game this season.
It is for this reason that Sky Sports claim Sakho wants to leave the club.
A move to Crystal Palace is on the rocks despite the two clubs agreeing on a fee between £10m to £12m.
This may be due to Sakho's desire to return to France.
In an interview with French journalist Claude Atcheba, the 28-year-old said that he wanted a "change of scenery" and "France provided a good challenge."
