Crystal Palace dominated Arsenal 3-0 on Monday night to increase the pressure on Arsene Wenger while boosting their own Premier League survival hopes.
Andros Townsend and Yohan Cabaye scored in each half for Palace before Luka Milivojevic's penalty ensured the surprise result at Selhurst Park on Monday night.
Townsend opened the scoring in the 17th minute, racing onto a low cross from Wilfried Zaha to slam home from the centre of the box.
Christian Benteke had chances on both sides of half-time to double Palace's lead but was denied first by Arsenal keeper Emiliano Martinez and then had his shot blocked by Hector Bellerin.
