The Gabon international almost put his side through to the next round with a terrific volley goal in extra-time.
Unfortunately, defensive errors led to the visitors scoring in the 119th minute and going past on away goals. Aubameyang did have a final opportunity at saving Arsenal but could not tap the ball in from six yards away.
“I don’t even know. I feel very, very bad,” the striker told BT Sport as he attempted to explain the miss. “This can happen. I don’t know how I missed this chance. I was tired and I had some cramps as well, but it is not an excuse. I have to score this goal, but it can happen.”
Aubameyang added on Arsenal’s exit from the competition, “What can I say? It’s very, very hard, very tough. It was a tough game again. I think we missed putting some pace in the game – that cost us a little bit. Then the last minute goal was unlucky for us. That’s it.
“We try to keep improving in the league and we’ll try to win as many games as possible, and we’ll see how many chances we have to qualify [for the Champions League].”
