Arsenal suffered another setback in their bid to finish in the Premier League top four, after they were battered 3-0 by Crystal Palace on Monday night.
Sam Allardyce’s men opened scoring with their first shot on target, with Andros Townsend turning in Wilfred Zaha’s cross.
Zaha and Townsend were both involved in Palace’s second goal too, with the Ivory Coast international picking out Yohan Cabaye to produce a brilliant dipping finish.
Luka Milivojevic converted a penalty for his first Premier League goal, to complete an impressive win at Selhurst Park.
Allardyce has now won five of his last six matches, while Wenger’s men have now lost four successive away Premier League games, conceding three goals in each.
