Olivier Giroud scored twice as Arsenal bolstered their hopes of Champions League qualification with a 4-1 victory at Stoke City.
The visitors found the breakthrough four minutes before the break through Giroud, who was on hand to tap into an empty net following Hector Bellerin's ball.
And Mesut Ozil doubled Arsenal's lead 10 minutes into the second half, latching onto Alexis Sanchez's through ball before finishing cleverly past Jack Butland.
Stoke pulled one back in the 67th minute through Peter Crouch, who appeared to turn Marko Arnautovic's cross in with his hand.
But despite seemingly having just picked up an injury, Sanchez made sure of the result nine minutes later with a low strike into the bottom corner, with Giroud adding a fourth late on after converting Aaron Ramsey's delivery.
