Bukayo Saka admitted that Arsenal gave their fans a heart attack in their win over Benfica.
The Gunners were heading out of the Europa League before Pierre-Emerick Aubameyang nodded in an 87th minute winner.
Arsenal gave themselves a mountain to climb in the second-half when Dani Ceballos’ error allowed Rafa Silva to put the Portuguese side 2-1 up.
Kieran Tierney levelled proceedings before Saka’s crossed for Aubameyang to make it 3-2.
It completed a rollercoaster of a night, but the young winger was still keen to have a repeat.
Arsenal will now advance into the last 16 of the Europa League.
Match winner Aubameyang, who has come in for criticism recently, claimed their display in Athens was the blueprint for what they will do moving forward.
He said on BT Sport: “Definitely. I think the team showed a lot of character and I think we deserved the win.
“It was a hard game but tonight really happy for all the team.
“What we showed tonight, I think it’s going to be an example for the future.”
Mikel Arteta defended his striker earlier this week and his faith was underlined by Aubameyang’s performance.
The 31-year-old missed several chances in the first-leg last week, but Arteta was thrilled with the way he responded.
“I completely trust him because he is producing the chances, and you know when Auba has chances he’s going to score goals,” he said.
“The last few days after the game in Rome against them, where he missed three or four opportunities and normally they are three goals for him.
“He needed to react and it was great to see the way he reacted is being upset and trying to be better – and not just feeling sad for yourself in this moment.
“I am really pleased with what he’s done tonight.”
