West Ham United let a lead slip as their six-game Premier League unbeaten run came to an end against Crystal Palace on Saturday.
The Hammers looked set to extend their rich vein of form when Sebastien Haller finished off a magnificent team move nine minutes into the second period, only for the visitors to turn the game on its head.
Patrick van Aanholt levelled from the penalty spot shortly afterwards, then Jordan Ayew struck the killer blow three minutes from time, knocking home from close range to score a goal that a lengthy VAR check confirmed.
