Arsenal have lost their first encounter against the 2012/13 bridesmaid in the UEFA Champions League - Borussia Dormund, but Aaron Ramsey is optimistic that the Gunners are capable of exacting vengeance against the German side.

"I thought we played well enough to get something from the home game," Ramsey told arsenal.com.

"The group is wide open again. It is going to be tough but we are still confident we can qualify."

The Gunners will be visiting the Signal Iduna Park on Wednesday after falling 2-1 at home on matchday 3, and Ramsey knows that it is tough to secure a win at Dortmund's home turf.

"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," he said.

"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."

The Welsh international player cautioned his teammates to be more cautious when attacking, as Dortmund is as equally deadly on the counterattack as they are attacking.

"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," he emphasised.

"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."
