Speaking to Sky Germany, the former goalkeeper said: "Because now it's Borussia Dortmund's turn. They can play completely freely. [Madrid] is an absolute title machine, especially in the Champions League. Dortmund is not seen as the favorite. This is their big chance."
He added: "To some extent, luck is also a factor. A solid team effort is needed. You can't give Real any room - just like in the semi-finals against Paris [Saint-Germain]. You can't let the individual class of the Madrid players, such as Vinicius Junior, come to the fore. Then you have a chance."
