Goals from former midfielder Cheikhou Kouyaté and Jordan Ayew saw West Ham United defeated 2-1 at Selhurst Park by Crystal Palace.
Robert Snodgrass had put the Irons in the lead on 57 minutes with an excellent finish, with the Irons seemingly heading towards a late Christmas present in the Boxing Day fixture, but Kouyate's low finish just 11 minutes later brought the game level.
With just moments left, Ayew's piece of skill and lofted finish was enough to beat Roberto in the West Ham goal.
