David Moyes's side had carved out a three-goal lead with just over half an hour gone as Jesse Lingard, Jarrod Bowen and Tomas Soucek capped off a blistering start.

But a Soucek own goal late in the first half swung momentum toward the Gunners, who set up a thrilling finish by forcing Craig Dawson to put through his own net with 30 minutes remaining.

And Alexandre Lacazette completed the comeback late on as he headed home from close range to steal a share of the points.
