Arsenal striker Lukas Podolski says a win against Anderlecht on November 4 would be enough for the Gunners to qualify.
Arsene Wenger's men were below their very best on Wednesday night but still managed to produce a late comeback to take all three points against a determined Anderlecht team.
"It was a dramatic game for the fans and for us as well but at the end we have the three points," Podolski told Arsenal Player.
"If we lost today it would have been difficult. It was important that we won and went back to London with the three points.
"I hope [we can gain momentum]. We had 25 shots on target against Hull City and we drew.
"Today was not the best game but it's important that at the end you get the points and we have the points.
"Sometimes you have to be a little bit lucky and today was the day. When the ball is on my left foot I score 99 per cent of the time.
"It was a good moment for me and the fans because they support me all of the time.
"We still have three games left and nothing is certain yet. We have an important game against Anderlecht at home and if we win that then I think we can go through."
