The BVB CEO feels his side have announced themselves to the world after being "finished" less than a decade ago
Borussia Dortmund chief Hans-Joachim Watzke believes that his side are back among Europe's elite after being "finished" just eight years ago.
Jurgen Klopp's side face Malaga in the Champions League quarter-finals on Tuesday and the 53-year-old has hailed their achievements following their brush with bankruptcy.
"Borussia Dortmund were finished eight years ago and now we belong to the cream of European football," the 54-year-old told Uefa.com.
"We are the only club unbeaten, which alone is extraordinary. If we make the semi-finals – alongside Barcelona, Real Madrid and Bayern Munich – then you could rightly say we are at the top level in Europe."
BVB drew 0-0 in the first leg against Malaga and midfielder Sven Bender says they need to remain cautious in order to progress to the semi-finals.
"0-0 was a dangerous result," the 23-year-old added.
"We have to keep the balance between attacking football and a good defence. The worst thing would be for us to be hit on a counterattack."
