Haven’t seen any of it, couldn’t believe it when someone told me.
Last time this happened to them they had a root and branch review of their entire setup which has been help up as the envy of World football.
To me it looked like a few key players were under cooked or out of form.
Neuer, Boateng, Hummels, Khedira, Ozil, Draxler all looked way below the standards you normally get from them in a Germany shirt.
My guess is big changes starting with the manager hopefully they try and get Klopp from Liverpool.
