Last weekend Arsenal's players took 828 touches on the ball during their 4-1 victory over Norwich; Dortmund had 713 in their 1-0 win over Hannover 96 in the Westfalenstadion. There will be some magic moments..
"The German teams have a desire to play and they come with a positive attitude," said Wenger.
"We have some German players and we know their quality. It makes it an open game . . . they don't hide. We don't hide and it will be exciting. We are always looking for perfection and that keeps me going as a manager.
"What is good for me is that after a period of frustration for our fans we can make them happy again and let them enjoy the game."
