The Poland international says it would be "crazy" to think that he could equal his four-goal haul against Los Blancos at Signal Iduna Park.
The Bundesliga outfit upset Los Blancos in the last four just under 12 months ago, with Jurgen Klopp's men progressing to the final after a dramatic 4-3 aggregate win, but the Spaniards now look all but certain to gain revenge, having routed BVB 3-0 in the first leg of their quarterfinal tie at the Santiago Bernabeu last week.
Indeed, while Lewandowski — who netted four times in last year's stirring first-leg win at Signal Iduna Park — says that he and his teammates will give their all on Tuesday, he cannot foresee a Schwarzgelben side shorn of the services of several key players upsetting Madrid again.
"Last year, we were a different side," the forward said during a pregame press conference. "It would be crazy to think I could score four goals again. But we are always dangerous in Dortmund. We have lots of injured players, but still a lot of potential. We still have a minimal chance and we want to give everything."
Lewandowski will start against Madrid after missing last week's first leg in the Spanish capital because of suspension.
