Arsene Wenger believes Tuesday's crunch fixture with Borussia Dortmund will be an open affair.
The Gunners currently have a large German contingent, with Mesut Ozil and Per Mertesacker likely to play against Dormund.
They also have Lukas Podolski out injured, while teenager Serge Gnabry could start as a sub.
And Wenger praised the German's attitude:
"For me, the most common thing about German players is their attitude," said Wenger. "They have a reputation of being 100 per cent professional."
The Arsenal chief - who turns 64 as his side face Dortmund - also talked up the attitude which German teams approach games with.
"What they give you, the German teams, is they have a desire to play. They play with a positive attitude and they have produced as well many good players recently.
"It makes it always an open game because they don't hide. We don't hide, so it should be an exciting game on Tuesday."
With Ozil, Mertesacker and Tomas Rosicky - formerly of Borussia Dortmund - in their ranks, Arsenal won't be lacking in players with a knowledge of the Bundesliga.
However, the Gunners boss is diplomatic in his evaluation of how much that may or may not help his side:
"It's difficult to weigh up how much that could help us," he said. "What is important is that we go into the game and focus on our quality and on our performance. For me that is more important than focusing on Dortmund.
"We want to come out of the game and feel that we have played at our best. If we do we will be difficult to handle for everybody."
