Ex-Germany captain Michael Ballack has warned the European giants against underrating Ghana when the two sides clash at the World Cup in Brazil later this year.
The Germans have been drawn in the Group of Death as they face Portugal, Ghana in the United States in what is considered a deadly and delicate group.
Germany have been touted as the overwhelming favourites for the tournament in Brazil in June thanks to the impressive showing of Bayern Munich and Borussia Dortmund in European competitions this season.
But Ballack, who played for Chelsea, says Germany must be wary of the threat posed by Ghana even though the Europeans are the favourites.
"Itâ€™s definitely not easy, although Germany are the favourites," the former Germany captain Ballack said.
"Itâ€™s an even group with another very strong European side in Portugal, Ghana, one of the strongest teams in Africa, and USA, who have improved a lot under Jurgen Klinsmann, who are always really well prepared in a physical sense and can always cause an upset against the bigger sides.
"Still, I think Germany will get through, though."
Ghana will open its World Cup campaign the United States, Germany and Portugal.
