​Borussia Dortmund chief Lars Ricken said Bundesliga clubs have a duty to act after another botched World Cup for Germany, adding that Jürgen Klopp cannot be the sole saviour of German football.Klopp as the likely future national team coach was “the all-round problem-solving package,” Dortmund’s managing director and former Germany midfielder Ricken told reporters on Tuesday on the sidelines of Dortmund’s first day of pre-season training.AdvertisementAdvertisementAdvertisement”But ultimately we as clubs are responsible and have a duty to train players in such a way that they can make the difference at a World Cup.”The 2002 World Cup runner-up was shocked by Germany’s recent exit in the round of 32 against Paraguay.”The performance of our national team is anything but satisfactory. I was at the match against Ivory Coast myself. If we had lost there, it would not have been undeserved either,” Ricken said.After a 7-1 win over Curaçao in their opener, the Germans narrowly won 2-1 against Ivory Coast after a late comeback, then lost 2-1 to Ecuador in their final group match and were beaten by Paraguay on penalties in the first knock-out round.AdvertisementAdvertisementAdvertisement”I can also understand the debate about the quality of the players,” Ricken said. “But as Germany, no matter who is on the pitch, you should beat Ecuador and Paraguay.”Germany coach Julian Nagelsmann resigned after the third straight early World Cup exit and former Dortmund coach Klopp is set to take over if a deal can be done with current employers Red Bull, where he is Head of Global Soccer.”What does he bring? Authority, experience, of course also a sense of a new beginning … and a certain clarity,” Ricken said. “I think that will do us extremely good. We get all of that, but that still does not get us a win. We (as clubs) have more of a duty than the national coach.”
