The Gunners shocked eventual competition winners Bayern at the Allianz Arena last season, and although the win was not enough to stop their elimination, it signalled a rebirth of sorts.
Since then, Arsenal have won 12 of their 13 away games in all competitions, with just a draw to blot their copy book.
They are sitting pretty at the top of the English Premier League, and if they manage to beat Dortmund, will ensure their progress into the next round of this season’s Champions League at a canter.
While there can be few tougher tests in club football at the moment than taking on Dortmund at their own home ground, Wenger thinks last season’s win over Bayern gives Arsenal more than a little hope.
"We do take belief from Munich last season," he said. "We play everywhere to win. That will not change and we will have a positive attitude to this game.”
And Wenger feels his team is now more balanced both at home and away.
“Maybe we had not the same belief at home because we failed in a few big home games. You could feel there was a bit more scepticism and less belief at home, although hopefully we have got that behind us now after Liverpool."
Meanwhile, Wenger has reacted to the lyrical interview Jurgen Klopp gave to The Guardian ahead of tonight’s clash.
The Dortmund boss claimed that his team is like heavy metal to Wenger’s opera, but the Frenchman is not singing the same tune.
"I am not a great specialist in music," Wenger said. "Dortmund is a very good football team and Arsenal as well … therefore we should see a good symphony."
