Pierre-Emerick Aubameyang admitted last season's Europa League heartbreak against Olympiacos was in his head when he scored the winner to send Arsenal through to the last-16 against Benfica.
The Gunners captain's late header - his second of the game - saw Arsenal overcome a major scare to beat their Portuguese opponents 3-2 in the second-leg and 4-3 on aggregate in Athens.
One year ago, Aubameyang put a chance wide late on against Olympiakos as the Gunners exited the competition on away goals at the same stage, with the Gabon forward delighted to right the wrong of last year on Thursday night.
