The striker says the Liga giants were not thinking about last year's semi-final defeat when they took on BVB on Wednesday
Los Blancos were beaten 4-3 on aggregate in the semi-finals of the 2012-13 edition of European club football's elite competition, but a repeat of last year's defeat seems unlikely after Madrid's comfortable win in the first leg of their quarter-final tie courtesy of goals from Gareth Bale, Isco and Cristiano Ronaldo.
"I don't want to talk about revenge, only of Wednesday's game, which was a great one from our point of view," Benzema told the official Uefa website.
"We scored three without reply, a very important achievement ahead of the second leg. I'm very happy with the result.
"I don't know if that advantage is enough. We will see about that in the next game but for now we feel good.
"We will look to keep fighting until the end because Madrid are a great team."
The return at the Signal Iduna Park is scheduled for April 8.
