The Gunners head into the game looking to claim their first European points of the season after disappointing defeats by Dinamo Zagreb and Olympiacos in their first two group games.
Arsenal have won only one of their four home games against Bayern in recent history.
And Wenger, whose side beat Watford 3-0 to move into second place in the Premier League table, concedes that the Gunners will have to be at their best if they want to have any hope of beating Pep Guardiola’s men.
“The confidence level is there, the needed result is there as well – we know exactly what is required [because] a 0-0 is not even a good result. To score goals, we have to attack,” Wenger told Arsenal’s website.
“It is true that [we have delivered big results] before, but we want to do it again because we feel a bit that the pain inflicted [in the Champions League] was a bit by ourselves. Maybe subconsciously we thought ‘anyway we will win these [first two games]’.
Arsenal’s home record against German clubs is W10 D1 L5; overall it is W15 D6 L11.
“Now to correct that we need a great performance. What we want to do is play up to our level – that will be needed because we play against a big team.”
Bayern have scored eight goals with no reply in their first two fixtures, winning 3-0 at Olympiacos and 5-0 at home to Dinamo.
The German side have won on their last two visits to Arsenal, which were both round of 16 first-leg assignments.
