Goals from Mateta, Ayew and Zaha were enough to condemn Arsenal to a defeat at Selhurst Park on Monday night.
Mikel Arteta’s men failed to turn up all night as Arsenal Legend, Patrick Viera executed his game plan to the end.
The defeat means Arsenal’s top four push took a blow, with their London rival, Tottenham Hotspur sitter in 4th, but only topping the Gooners on goal difference.
Arsenal have a game in hand, and will reclaim their spot if they win that game. Palace now sit in 9th, with 37 points, same with Leicester City.
