The German side takes on the Spanish giants in the Champions League quarter-final second leg at Signal Iduna Park on Tuesday night after losing 3-0 at the Santiago Bernabeu last week.
Despite trailing so heavily to a very dangerous team, Australian gloveman Langerak is of the belief that BVB can bridge the gap with Real in front of die Schwarzgelben faithful.
"Our Champions League adventure isn't over, even if we lost the first leg 3-0.
"We're always capable of scoring one or two goals, especially at home. We can, and we need to. We'll just have to see what happens."
"I can't say. For the team's sake, I hope Roman recovers by Tuesday," he added.
