The former Chelsea midfielder thinks that Joachim Low's men need to find a left-back solution and spoke about who might play in attackGermany icon Michael Ballack says the nation are "desperate" to win the World Cup next year following Friday's group stage draw.
Joachim Low's men were pitted against USA, Ghana and Portugal in Group G, with a clash against former coach Jurgen Klinsmann a particular highlight.
Klinsmann's former Mannschaft captain Ballack, knows that his former coach has a major challenge ahead and hopes that they can shake off their defensive issues to challenge for the trophy in Brazil next summer.
"I know Germany is well prepared," Ballack told Goal. "They are a good team but they're desperate for success, for a title and they will go for the title I'm quite sure.
"There are not many weaknesses, but if you talk about one certainly it is left-back. We have been struggling for a long time because for a long period, Philipp Lahm played there, then he swapped to the right side.
"The centre-backs are not weaknesses, but we have to find the right couple. The coach still needs to find the right couple for the starting XI and left-back."
Ballack also lauded the talent of strikers Miroslav Klose and Mario Gomez but hinted that the World Cup 2010 semi-finalists will continue their recent habit of fielding 'false nines'.
"I'm sure with Klose and Gomez, we have two really good strikers and they will play when we need them," the former Chelsea midfielder said. "But it's all about the decision by the coach, how he feels comfortable."
