Arsenal won at Crystal Palace to move within a point of fourth-placed Liverpool thanks to two goals by Alexis Sanchez.
Shkodran Mustafi opened the scoring when he poked in after Palace keeper Julian Speroni parried Alexandre Lacazette’s shot.
The hosts caught out a static Arsenal defence early in the second half to equalise – Andros Townsend turning in Wilfried Zaha’s cross from close range.
Sanchez restored the Gunners’ lead when he squeezed a clinical strike in at Speroni’s near post before the Chile international added a third four minutes later, bringing Jack Wilshere’s superb ball under control and flicking into the net.
Palace set up a nervy finish when James Tomkins headed home from a corner inside the final minute, but Arsenal held on to ensure Arsene Wenger marked equalling Sir Alex Ferguson’s record of managing in 810 Premier League games with a victory.
