Germany manager Joachim Loew has announced 30 players now, it will reduced down to 25 for the training camp and then 23 players will be selected before the 2 June deadline.
Sami Khedira is in despite having not played since November with ACL injury.
But considering the hot and humid conditions in Brazil, Loew will probably take a great concern over the fitness of some of the crucial members of the squad.
