The Gunners head to the Allianz Arena to take on Bayern Munich in the Champions League Round of 16 second leg and Wenger feels there could be a massive reward for his side despite them losing the first fixture 3-1 in north London three weeks ago.
"I am convinced that if this team can find a big game, with a big win, you will see a completely different animal," he told reporters.
"This season we have fought to find that in the big games and we have another opportunity tomorrow night and I hope the team takes this chance.
"I have a great respect for this team and its attitude and they have not been rewarded yet. It is important for the end to our season that we do it tomorrow."
