Arsenal's Champions League qualification hopes were damaged further by a 3-0 loss at Crystal Palace on Monday in the Premier League.
Sam Allardyce had lost 15 times to Wenger in the league previously but the hosts' resurgence under the former England manager continued with their fifth win in six games - which now includes the scalp of Arsenal having also beaten league leaders Chelsea.
Palace opened the scoring with their first shot on target, Andros Townsend turning in a low cross from his fellow winger Wilfried Zaha after Arsenal failed to deal with a long ball.
Zaha and Townsend were both involved in Palace's second goal too, with the former picking out Yohan Cabaye for a brilliant finish, and Luka Milivojevic converted a penalty for his first Premier League goal to complete an impressive victory over a limp Arsenal side.
Wenger's men have now lost four successive away Premier League games, conceding three goals in each, and their chances of qualifying for the Champions League - as they have every season under the Frenchman - are fading fast, with a seven-point gap to make up on fourth-placed Manchester City.
