Christoph Metzelder has warned Borussia Dortmund that they cannot afford to neglect their defensive duties against Real Madrid if they are to have any chance of success in the second leg of their Champions League quarter-final tie.
BVB were beaten 3-0 at the Santiago Bernabeu last week and have no other choice but to attack in the return leg at Signal Iduna Park on Tuesday evening.
However, Metzelder has stressed that it would be a huge mistake to ignore Madrid's brilliance on the break.
"I think Dortmund will go out with everything they have early on and try and create an atmosphere where the players can outdo themselves," the former Germany international told Goal.
"Dortmund are able to defend very disciplined and to force their opponent into making mistakes.
"It will be crucial for them to find the right balance, though, because Real Madrid will punish them without mercy. If Madrid score an early goal, Dortmund's morale will be shot."
The 33-year-old, who played for both BVB and Madrid during his top-level career, expects the Liga giants to progress to the semi-finals yet can still foresee Dortmund winning the second leg.
"They got a few good chances to score in the away game," Metzelder said of Jurgen Klopp's side. "On the other hand, I got the feeling that Madrid could step it up a notch whenever they wanted.
"Their defensive display also impressed me. Both Sergio Ramos and Pepe were superb in difficult situations. The centre-backs at Madrid often suffer because the team wants to attack, but they did really well in the first leg.
"Dortmund might improve with the return of Robert Lewandowski [from suspension] and they will be more dangerous.
"I can even see them winning the return leg. I doubt that it will be enough to reach the semi-finals, however.
"Madrid will be very motivated to win the second leg as well. We all saw them against Schalke [in the last 16]."
