Crystal Palace are now six points above the Premier League relegation zone after a 3-0 victory over Arsenal at Selhurst Park.
Andros Townsend opened the scoring in the 17th minute, converting from close range after Wilfried Zaha teed him up despite losing his footing.
The impressive Zaha was the creator again, cutting back in similar fashion for Yohan Cabaye to curl a superb effort into the far right corner of Emi Martinez's goal just after the hour mark.
Five minutes later, Martinez tripped Townsend in the penalty area, with Luka Milivojevic finding the left corner with his spot-kick.
Palace remain 16th despite the victory, while Arsenal are in sixth position, seven points adrift of fourth-placed Manchester City with a match in hand.
