Diafra Sakho could be staying in London for the time being - but almost certainly not with West Ham.
The forward has been used largely as a second-half substitute in the Premier League this season under Moyes, scoring twice in his 14 appearances.
Sakho has now been given permission to hold talks with Palace and undergo a medical at Selhurst Park.
The West Ham United forward is the subject of a £10 million bid from Crystal Palace, according to reports.
Whilst the 28-year-old has been a reliable servant to West Ham, the aforementioned figure would represent fantastic business for the club, and would allow David Moyes to strengthen in other areas of his squad.
Their results have improved since Roy Hodgson took charge but form of star striker Christian Benteke, who has just one league goal, suggests the Eagles would benefit from another attacking threat.
"We are doing it as best we can and as professionally as we can".
The striker whose summer move to Ligue 1 side Rennes infamously collapsed on deadline day is understood to have grown frustrated at the Hammers. "We don't want to bring players in for the sake of bringing them in".
