Joachim Löw is rolling the dice, and letting Reus, Schürrle and Klose start.

Müller, Podolski and Gomez (despite scoring 3 goals in the group stage) all go to the bench to make way in the starting formation.
I hope Löw's not outthinking himself. He's been pretty good about tactical decisions, so I have to have faith that he knows what he's doing.
Let's hope that the big changes don't mess up team chemistry.
