Pierre-Emerick Aubameyang rescued Arsenal's Europa League campaign from the jaws of defeat as his late winner secured a dramatic 3-2 victory over Benfica in Greece
Arsenal were staring down the barrel of elimination at the round-of-32 stage for the second successive season after Diogo Goncalves' stunning first-half free-kick and Rafa Silva's second - after a costly Dani Ceballos error - gifted Benfica the advantage after Aubameyang's opener
The collapse left Arsenal with half an hour to salvage their season, and they rose to the challenge in thrilling fashion
Kieran Tierney's venomous strike sparked the comeback, which was sealed with three minutes remaining when Aubameyang peeled away to the back post to head in Bukayo Saka's cross, and Arsenal into the last 16 of the Europa League after a 4-3 aggregate win
With their hopes of a top-four finish floundering and their chances of domestic cup silverware over, it was make or break for Arsenal at Olympiakos' Georgios Karaiskakis Stadium, the stand-in venue for their Europa League round-of-32 second leg in light of the UK's strict coronavirus travel rules
But despite being almost 2000 miles away from the Emirates Stadium, the Gunners were at home, quickly outnumbering Benfica in midfield and establishing control of the contest
In a game of season-defining importance, Arsenal nerves were settled on 21 minutes when Aubameyang latched onto Saka's perfectly-weighted reverse pass and floated the opener into the Benfica net to give the Gunners, after a VAR review, the lead in the tie for the first time
Former Tottenham defender Jan Vertonghen headed Benfica's first chance harmlessly over as Arsenal cruised towards a half-time lead, but they were stopped in their tracks by a moment of individual brilliance
After Ceballos was penalised for a needless foul on midfielder Julian Weigl, Goncalves whipped an unstoppable free-kick into the top corner of Bernd Leno's goal to hand Benfica a crucial away goal with his first for the club
Aubameyang had the ball in the Benfica net early in the second half in almost identical circumstances to his first-half strike, but this time the Gunners captain fell foul of a VAR offside review
Things took a turn for the worse on the hour when Ceballos' calamitous defensive header released Rafa Silva through on the Arsenal goal, and the Portuguese registered Benfica's second away goal of the tie which left the Gunners needing to score two unanswered goals
Benfica looked to have secured an unassailable lead but Arsenal had other ideas, with Tierney's fierce strike into the far corner breathing life back into the Gunners' campaign six minutes later
Substitute Darwin Nunez was unable to punish two defensive mix-ups involving David Luiz and Gabriel Magalhaes as Arsenal's hope of progressing hung perilously by a thread
But, with three minutes remaining, the Gunners completed their remarkable comeback and once again Saka was the creator, curling a sumptuous ball to the back post which Aubameyang stooped to head in as Arsenal booked their place in Friday's last-16 draw in the most dramatic of circumstances
The draw will take place on Friday, February 26 in Nyon's House of European Football at 12pm UK time
