''Our personal aim is 10 wins from 10 games,'' Germany coach Joachim Loew said.
Turkey and Belgium, meanwhile, are fighting to finish second in Group A for a playoff place.
''Germany hasn't been beaten for long time,'' Turkey coach Guus Hiddink said. ''We are not at their level. However, we believe we can cause upsets at home. I hope we defeat them here.''
Visiting Germany was prepared for a hostile reception at the Turk Telekom Arena, where Turkey will look to redeem a 3-0 loss at Germany one year ago.
''The Turks didn't show their true face in Berlin,'' Loew said. ''Tomorrow the Turkish team will be roared on by an enthusiastic crowd. There will be a lot of emotions in the game, there will be a lot of motivation.''
''I'd like to be able to make the team selection tonight,'' Loew said. ''All three will go to training today, but whether they'll be able to train or not is unclear.''
Loew acknowledged the loss of Oezil would be a big blow for Germany.
''He's the one who can make things happen. But if he can't play, we'll find another solution,'' Loew said. ''Mario Goetze is another who can play behind the forwards. Andre Schuerrle is another who can drop back.''
Hiddink has recalled midfielder Hamit Altintop despite the Real Madrid midfielder being sidelined all summer to a back injury. Paris Saint-Germain forward Mevlut Erdinc was also included in the squad, while Hakan Arikan has replaced injured goalkeeper Tolga Zengin.
Fenerbahce midfielder Emre Belozoglu - who was singled out as Turkey's main threat by Loew - has a slight injury but is expected to play.
''I believe our chance against Germany is 51 percent,'' midfielder Arda Turan told Turkish TV. ''Germany is a world-class team but in a match played in our country, nothing should scare our team or fans.''
Four Germany-based players could play for Turkey, with Bayer Leverkusen defender Oemer Toprak in line for his debut after choosing Turkey over Germany where he played at youth level. Striker Tunay Torun and midfielders Mehmet Ekici and Goekhan Toere are the other three.
''A player should not decide which country he represents for sporting reasons,'' Loew said. ''A player has to decide himself without pressure from the coach.''
