Real Madrid defender Pepe admits their performance was error-ridden in defeat to Champions League opponents Borussia Dortmund.

Robert Lewandowski struck four times in the 4-1 win.

Pepe said: "We did not start the match well. We expected a lot from them and made expensive mistakes. But the important thing is that we can turn around the tie and get to the final. We have to think about ourselves. We played badly and we have to accept it, but there is still a match to go."
