The current United States trainer, who has played for and coached at Bayern, is confident his old team can end their European disappointment but praised the Schwarzgelben attitude and quality at high pace.
"The enthusiasm!" the ex-Germany international told Spox, when asked what he admires the most about Dortmund under Klopp.
"The enthusiasm, the pace and conviction. Dortmund has some players who are technically superior to their competition and can play at the highest speed."
"Klopp became a German champion with Borussia Dortmund and is now in the Champions League final - for me he has already arrived at the highest level. You must be a good coach when you build something great like Dortmund."
When asked to make his prediction for the final at Wembley on Saturday, Klinsmann admitted that it has been an unpredictable competition this year but feels that his former club will triumph on the night.
"It is a single game, in which many uncertainties may happen and somehow those uncertainties would fit well with the course of the Champions League season. But based on the experience of recent years, the favourite in this final is Bayern Munich."
The German coach currently has the task of helping the US qualify for World Cup 2014 after parting company with the Bavarian club in 2009.
