Borussia Dortmund's Mats Hummels has said it's important his side look to keep a clean sheet against Real Madrid tonight but is also hoping to come out with victory.
The two sides clashed in the group stages of this Champions League campaign with BVB sealing a 2-1 victory over Madrid at the Westfalenstadion and earning a hard fought draw at the Santiago Bernabeu.
Hummels thinks the memory of these results will definitely stick in the minds of both sides during Wednesday's match.
"We know how good we can be and what teams can expect from us if we play to our potential and the crowd gets really loud," Hummels told Borussia Dortmund's official website. "But we also know from the second game how good they are, they upped the pressure and caused us some real problems, both with and without the ball."
The big German defender, who has just recently returned from injury, is set to feature against last season's Spanish champions and has urged his Borussia Dortmund teammates to focus on keeping Real Madrid quiet if they hope to reach the final.
"It will be crucial that we attack and defend as a whole team," he added. "If all 11 players have the same idea we are very difficult to beat."
Jose Mourinho's men are the highest scoring team left in the competition and keeping a clean sheet will be no easy task.
Hummels knows that, aside from Cristiano Ronaldo, Real Madrid have plenty of other very dangerous players who are capable of turning the game on it's head at any time.
He said: "Real are a lot more than Cristiano Ronaldo and have a top player in every position. But that partly applies to us as well."
