The Germany legend admits he "had a feeling" he would draw Joachim Low's side and is wary of the threat posed by Ghana and Cristiano Ronaldo's Portugal.
Klinsmann's charges have been placed in Group G alongside Germany, the country he represented in 108 internationals, as well as Cristiano Ronaldo and Portugal and Ghana, which knocked USA out of the last two World Cups.
Although Klinsmann insists he will head to Brazil next year with a positive mindset, he acknowledged the scale of the task facing his team.
"It's one of the most difficult groups in the whole draw," the 49-year-old said. "Including having Portugal and [Cristiano] Ronaldo, Ghana's history with USA and, of course, Germany, it couldn't get more difficult or any bigger.
"But that's what the World Cup is about and we'll take it. Hopefully we’ll surprise some people there. We're going to be prepared. We're going to be confident."
Pressed on the subject of facing his fellow countrymen, Klinsmann added: "I had a feeling in my stomach we'd get Germany."
