Dortmund: Captain Iker Casillas said Real Madrid were given a UEFA Champions League wake-up call as they lost 2-0 to last season's beaten finalists Borussia Dortmund in their quarter-final second leg match but still went through to the last four 3-2 on aggregate on Tuesday. Germany winger Marco Reus scored both Borussia's goals to spark hopes of the hosts reaching the semi-finals.
However, Real held on but patently missed their star performer Cristiano Ronaldo, who was on the bench because he had not recovered fully from the knock to the knee he took in the first leg. "Maybe it's good for us to receive a wake-up call like that from time to time," said Casillas.
"We committed errors at the back that cost us and we cannot commit in the semi-finals.
