As the competition reaches the latter stages his players are going to have to step it up a gear if they are to win him a record fourth Europa League trophy. Not sure what else to say.
After finding the back of the net in the 72nd minute and putting Arsenal up 3-0 against Rennes, Aubameyang broke out a "Wakanda Forever" salute while donning a Black Panther mask.
With the Ligue 1 side leading 3-1 from the first leg, Aubameyang and Ainsley Maitland-Niles scored in the first 15 minutes of Thursday's return to draw Arsenal level on aggregate.
Rennes gave Arsenal a real scare shortly after the half-time restart as Ismaila Sarr picked out the post with his shot, which took a touch on its way through, after Shkodran Mustafi was caught on the ball.
Maitland-Niles was being given plenty of room down the right-hand side and he made the most of that 10 minutes later when heading Aubameyang's cross past Tomas Koubek.
The striker was famous for his masked celebrations at Borussia Dortmund, wearing Spider-Man and Batman masks after scoring, but Thursday was the first time he performed one in an Arsenal shirt.
Aubameyang missed two big chances inside a minute to complete his first hat-trick in Arsenal colours, poking wide of the post with just Koubek to beat and then skewing wide of the same post once teed up by Ramsey in front of goal.
And the 29-year-old was on hand again to score a crucial third, meaning an away goal was not enough on its own to knock the Gunners out for Rennes. And Emery, as the resident Europa League specialist (a mantle he'd probably rather pass on now he's left Sevilla), duly delivered.
