Roland Eitel told Bild am Sonntag newspaper it was still unclear whether Klinsmann, who led an unfancied Germany team to third place, would return to the sidelines.

"Juergen has enough work to do right now," Eitel said, noting he had two years worth of work to catch up on at his California firm Soccer Solutions. Eitel said Klinsmann is also analyzing training and match data from his two years as coach.

Eitel said Klinsmann had received coaching offers from Mexico and the United States.

"And they're all serious," he said. But when asked if Klinsmann would take any job, Eitel said: "We'll have to wait and see."

Klinsmann said after the World Cup he planned to take six months off before making any further plans.

Ricardo La Volpe left Mexico after his contract ended after they lost 2-1 to Argentina in the second round at the World Cup in Germany. La Volpe moved to Boca Juniors, the most popular club in his native Argentina.

U.S. coach Bruce Arena's contract was not renewed after the Americans were knocked out of the World Cup at the group stage. The president of U.S. Soccer, Sunil Gulati, has identified Klinsmann as a top choice.
