Jeffrey Schlupp's first-half goal and Tyrick Mitchell's stoppage time strike gave Crystal Palace the victory over Burnley at Turf Moor.
Jordan Ayew drove into the penalty box in the 22nd minute, before squaring the ball across the six-yard box for Schlupp to apply the finishing touch.
Burnley had the ball in the net, but it was ruled out for offside, but Mitchell compounded Burnley's misery at home deep into stoppage time.
It is yet another home defeat in the Premier League for Vincent Kompany, who remains under pressure as the Clarets still seek their first win at Turf Moor since being promoted.
