Khedira winning fitness battle
Khedira has been struggling with a thigh injury but Germany assistant coach Hans-Dieter Flick is confident the former Stuttgart man will be available for the clash in Vienna.
"With Sami all has gone to plan and we are on target," said Flick today. "His muscle injury has healed. He trained with the ball yesterday and will do so today.
"We are confident he can play on Friday but we won't take any risks. He won't play if he is not fully fit as we have a commitment to the players."
Cologne's Lukas Podolski remains a doubt for a game against an Austrian side Mesut Ozil believes should not be taken lightly.
Khedira's Real Madrid team-mate said: "For Austria it is their last chance in qualifying and they will be extremely motivated.
Bayern Munich's Toni Kroos added: "The game should be explosive and the crowd will make a great atmosphere. But if we are focused we should prevail as we are the better team."
Germany currently top Group A with maximum points from their five games. Austria are fourth but just three points behind second-placed Belgium with a game in hand.
