Arsene Wenger wants Arsenal to make the most of their second chance in the Champions League ahead of the last-16 return at Monaco on Tuesday with the club aiming to rewrite history and stay in the competition.
Arsenal's hopes of reaching the quarter-finals were hit after a 3-1 home defeat in the first leg - conceding in stoppage time just minutes after a late goal from Alex Oxlade-Chamberlain made it 2-1.
Monaco have one of the best defensive records in Europe, and no team has recovered from more than a single-goal deficit going into an away leg in the Champions League era.
Wenger though believes Arsenal can produce an unlikely result against the club he guided to the French title 27 years ago.
"We have to put it right," he said. "Sometimes in life, you make a big mistake, and there is no comeback - no way you get the chance to put it right again.
"In football, you can do it, so let's just give everything to do it. We know that, in the first leg, we were impatient and threw ourselves forward too much - that we lost our patience and composure.
"We wanted too much to make a difference in the first game and forgot our basics - that means to defend well and attack well.
"We just focused on attacking well, but because a goal didn't go in, we opened ourselves up."
Wenger added: "We are in a position where Monaco is favorite. People think they have already won it, but they can still lose it.
"We can go there and create something special. I believe that we will have the desire to do it and give absolutely everything to do it."
