Borussia Dortmund defender Lukasz Piszczek believes that his side have "nothing to lose" against Real Madrid in the Champions League semi-finals.

The German club will host the defending Spanish champions in the first leg at Signal-Iduna Park on Wednesday.

"We're expecting a very tough game," he told Bundesliga.com. "I think Real have improved a lot since we played them in the group stages, but we've got nothing to lose.

"We've had a terrific Champions League campaign so far, which is why we're determined to get a good result against Real.

"We want to win but a goalless draw wouldn't be bad. Against Malaga [in the quarter-finals] we saw for ourselves just how difficult it can be at home after a 0-0 draw in the first leg."

Madrid failed to beat Dortmund when the sides met twice in the group stage of the competition earlier this season.
