Bad: Shkodran Mustafi is injured. Good: Germany playing players in actual positions now.

Shkodran Mustafi is a central defender with some, but not much experience at right back. Jerome Boateng is a central defender with extensive experience at right back. Philipp Lahm is a right back with some experience at central midfield. For reasons unbeknownst to anyone, Jogi Löw has been playing Mustafi as a right back, Boateng as a central defender and Lahm as a central midfielder. It's been awful, because duh.

But then Mustafi went down with a pretty nasty non-contact lower leg injury, and he's been substituted in the 70th minute against Algeria. His replacement was central midfielder Sami Khedira, which moved Lahm to right back. Germany have now improved significantly because of an injury.
