Speaking after their 1-0 win at the Signal Iduna Park, Arsenal mentor Arsene Wenger comments on his side's recent win against Borussia Dortmund as better than their away-leg win against Bayern Munich in 2012.

"People think that maybe [Bayern] Munich took it a bit easy, which I did not think at the time, but it was true they had beaten us 3-1 at home and maybe in their head had already qualified.," Wenger told arsenal.com.

"Tonight both teams had to win and I must say we had to win even more because we lost at home and knew we had to go to Dortmund and Naples."

Wenger highlighted the fact that the Gunners took good care of the ball throughout the game, which prevented Dortmund from creating scoring opportunities out of interceptions.

"We looked more stable defensively because we have experience in midfield not to lose the ball in stupid positions," he added.

"Dortmund are especially dangerous when you lose the ball - to counter that, you need maturity."

The French tactician hailed the performance of goalscorer Aaron Ramsey, who has seemed to be very comfortable and adjusted to his role on the pitch for the Gunners.

"He just shows how difficult it is to have assessment on players because one year ago everyone said 'yes, but Ramsey cannot score goals. He's in box in the right positions, but he can't score," revealed Wenger.

"This season he scores game after game. I was always positive with him because when you watched the games again he was always in situations where he could be dangerous."

Arsenal have immensely benefitted from their winning form in the English Premier League, which translated in players' gaining confidence as the season progresses.

"This season he has gained confidence and he has an unbelievable engine to go from box to box. Confidence and his ability of course makes him a dangerous player."
