Crystal Palace dealt a heavy blow to West Ham’s ambitions of playing European football next season with a 5-2 victory at Selhurst Park.
Palace, who had not previously scored more than three goals in a league contest this season, led by four inside 31 minutes, opening the scoring with a Michael Olise header before Eberechi Eze made it two with a superb bicycle kick.
Emerson intensified the Irons’ woes when he turned the ball into his own net before Jean-Philippe Mateta got on the scoresheet just after the half hour mark.
