Aaron Ramsey says Arsenal will be “a bit more streetwise” against Borussia Dortmund when the teams meet again.
A late Robert Lewandowski strike earned the German side a 2-1 win at Emirates Stadium last month as they caught the Gunners on the break to snatch the points.
Ramsey - who also played in the 1-1 draw at Westfalenstadion in 2011 - is looking forward to putting that defeat right in Wednesday's return fixture.
"We don't go anywhere with fear - we will approach it the same as any other game. It is a massive week and one that we are looking forward to"
"I thought we played well enough to get something from the home game,” the Wales international said. “The group is wide open again. It is going to be tough but we are still confident we can qualify.
“We have been to Dortmund in the past and drew there after we conceded a late goal. We have experienced what it is like there and we know it can be a very intimidating place to play. I am sure we have the quality and the players to get a good result and put ourselves back in control of the group.
“In the game at Emirates, we were a bit naïve - it should have at least finished as a draw. We switched off and they caught us on a counter-attack in the last 10 minutes and we paid the price, which will happen at this level. We will learn from that.
“We are confident. There were periods in the game when we felt very dominant and maybe could have scored a few but we will be a bit more streetwise going over there.
“Dortmund have a very organised team and a real work ethic. They also have a world-class striker [in Lewandowski]. They were runners-up in the Champions League last season so they know what the competition is all about.
“The atmosphere in their stadium is tremendous but you want to be playing in these sorts of atmospheres. Everyone in the team will be looking forward to it. We don't go anywhere with fear - we will approach it the same as any other game. It is a massive week and one that we are looking forward to."
