Germany are under pressure to win World Cup 2014 as they step up their preparation for the tournament, says Oliver Bierhoff.
Joachim Low's men, who qualified top of Uefa Group C with nine wins from 10 matches, will face USA, Ghana and Portugal in the group phase.
Bierhoff, who represented his country 70 times, is expecting a tough challenge in Brazil despite their favourites tag.
"The pressure is there, of course, and it's not going to be less," the 45-year-old told reporters.
"The desire of us, the fans and also the players is huge to win a title there in Brazil. We know we are one of the favourites, but we know it's a hell of a lot of work."
Sami Khedira is one player who will be hoping to earn a call-up to the squad but he must first overcome an anterior cruciate ligament injury in order to be considered, with Bierhoff confirming that a number of options are being weighed up.
He added: "Everybody has chances. I mean, we know the players for quite a while. So for example we know what kind of player Sami Khedira is, what kind of a character he has, his personality.
"But of course it's very important that a player is 100 per cent fit. Despite that, everybody has the same chances."
