Sixth-placed Arsenal, who have finished in the top four in 20 consecutive seasons under Wenger, now have 54 points from 30 games -- seven points behind fourth-placed Manchester City, who have played a game more.
"It's damaging of course," a seemingly dispirited Wenger told Sky Sports when asked about how serious the blow was to their chances of Champions League football next season. "That's the most difficult thing for us tonight."
Rejuvenated Palace, winners of four of their previous five league games under Sam Allardyce, started confidently and opened the scoring when former Tottenham winger Townsend swept the ball home at the end of a smart passing move after 17 minutes.
