Against Borussia Dortmund, Real Madrid failed to score without the injured Cristiano Ronaldo and only just hung on to advance to its fourth straight Champions League semifinal after losing 2-0 on Tuesday.
With its star striker on the bench because of a left-knee injury, Madrid could afford to miss an early penalty and still go through 3-2 on aggregate.
"We are pleased to have reached the semis, that was our goal. But we are not pleased with the way we did it,'' Madrid coach Carlo Ancelotti said.
Marco Reus scored in the 24th and 37th minutes, both times after Madrid mistakes, while Borussia Dortmund wasted several excellent opportunities in the second half, including a shot against the post.

Reus doubled the lead after another mistake by Madrid as it tried to move the ball forward. Reus passed to Robert Lewandowski, whose shot hit the post, but Reus was there to drive the rebound into the roof of the net.
"After we missed the penalty, they got the upper hand. We lost possession too often and we basically gifted them the goals,'' Ancelotti said. "It could have
