Borussia Dortmund centre-back Mats Hummels has revealed his pride at his side's stunning 4-1 victory over Real Madrid in the first leg of the Champions League semi-final.

In particular, Hummels was "delighted" with the way that his teammates responded to his mistake that allowed Cristiano Ronaldo to equalise on the night.

"I think we can be tremendously proud of the team's performance tonight," UEFA.com quotes him as saying. "The way we played was a measure of the players and I'm all the more delighted at how the team reacted to my mistake. The way we dealt with it and what we showed subsequently was fantastic.

"It's a superb result, obviously, but Real Madrid are even stronger at home. They're going to come at us for 90 minutes and we're going to have to defend against that.

"It's going to be the most difficult match of our careers, but if we can survive that test, we can all be very proud and that is, of course, our aim."

The two teams meet again on Tuesday night at the Santiago Bernabeu.
