Borussia Dortmund captain Sebastian Kehl admitted Real Madrid need to "create a miracle" to stop the Germans from making the final of the Champions League.
Dortmund travel to Spain for the second-leg of the semi-final clash on Tuesday with one foot in next month's showpiece event after storming to a 4-1 victory in last week's home tie.
However, Madrid are refusing to buckle in the face of adversity, manager Jose Mourinho believing "everything is possible."
But Madrid must match a slice of history to book their place in the final; only one team, AC Milan, has been knocked out of competition with a 4-1 first-leg lead.
But despite being wary of their cornered foe, Kehl is confident Dortmund are "ready for anything."
"They will try everything, they want to create a miracle," the 33-year-old told reporters.
"But we're prepared, we'll have to be fully focused on the match and then I'm sure we'll succeed.
"It's going to be a tough match, there's the danger Madrid will overrun us tomorrow, and therefore we'll have to be ready for anything."
However, there is one advantage that Madrid will be able to call upon for their all-or-nothing match against the Germans - the parochial Bernabeu crowd.
"We will try to continue bringing our positive attitude to the pitch in the Champions League," Dortmund defender Neven Subotic said.
"However, we know that our three-goal advantage doesn't guarantee us anything yet. We know that Madrid will appear a lot stronger at home than they did in Dortmund last week. "
