Despite James Tomkins ensuring a nervy finish for the visitor with an 89th minute headed goal, the win left Arsenal still in sixth place but they moved on to 37 points, alongside Tottenham Hotspur and to within a point of the top four. Palace, beaten for the first time in nine games, are 16th on 18 points, just a point above the relegation zone. There must have been much satisfaction for Wenger, whose own future at Arsenal had never been more hotly debated than when his side lost this same fixture 3-0 at Selhurst Park in April last season. That defeat inspired the Gunners' successful run which ended with an FA Cup triumph and Wenger will now be hoping this victory could start another impressive sequence at the start of 2018 as they chase Champions League football for next season.Arsenal have won more #PL London derbies (120) than any other side pic.twitter.com/KYggJHZkAL

What part Sanchez will play for him remains unclear but the Chilean, whose name has been consistently linked with a move to leader Manchester City, could not be faulted and neither, naturally, could his skill. After Townsend's well-worked equaliser assisted by a pinpoint Wilfried Zaha cross had changed the game's complexion, Arsenal's nerve were settled only when Palace striker Christian Benteke hit a poor clearance out of defence, a mistake that ended with Sanchez rifling home the visitor's second in the 62nd minute. Then Wilshere, back to something near his best, picked out a delightful over-the-top, quarterback-style pass that Sanchez controlled expertly on his thigh, before sliding the ball past Palace goalkeeper Julian Speroni. Sanchez's excellence prompted the inevitable question to Wenger afterwards about whether he was fearful of losing the Chilean, especially with the striker's contract expiring at the end of the season.Man of the Match, @Alexis_Sanchez4 shots 3 on target 2 goals 2 chances created 101 touches, most in match#PL #CPFCvAFC pic.twitter.com/E1ZSBQgEMe
