The Gabonese forward entered the FA Cup final against city rivals Chelsea with a reputation as one of the best forwards in the Premier League - and while others shrank under the spotlight, Aubameyang came up big with the match-winning brace.
He reaffirmed his reputation and some, scoring either side of half-time as Mikel Arteta's men ended a difficult domestic season with silverware.

The question now rolls onto what happens next and whether he decides to stick around
Christian Pulisic - who has had an impressive end to the season - had given the Blues an early lead but Aubameyang would show he is as cool as they come when presented with a chance to equalise from the spot.
Willy Caballaro, in for Kepa Arrizabalaga and known as a penalty specialist, was helpless, diving to the right as the ball flew in to the corner to his left.
He then truly proved why he deserves to be regarded among the world's elite, netting the winner with a sublime finish in the second half. The 31-year-old received the ball on the left hand side of the box and proceeded to turn Kurt Zouma inside out before lifting the ball brilliantly over Caballero.
It capped what has been another stellar season for Arsenal's undisputed main man, the striker having found the net 29 times in 44 appearances in all competitions.
Aubameyang scored twice as Arsenal beat Chelsea in the FA Cup final on Saturday night
In fact since his arrival in January 2018, no Premier League player has scored more goals than Aubameyang.
Saturday's brace took him to 70 in 109 games, two more than next highest Mohamed Salah.
Those numbers are remarkable and one can only wonder where his club would be without him.
But life without him is something Arsenal fans fear is a very realistic possibility in the not too distant future.
Aubameyang has just one year remaining on his current deal and he must now decide what he is to do with his final years at the top level.
He will be 32 by the time his contract is set to expire, meaning now could be his last chance to push through a move to one of Europe's biggest clubs.
