Agree. It's not just the losing, it's the manner of losing. It's the total absence of everything German with this current generation of players as you highlighted.
No fighting spirit or will.
No cohesiveness.
No organization and discipline (this is THE quintessential German trait)
This is how you go from the nation that won all 4 of its WCs beating super teams and GOATs (1954 vs. the Magyars, 1974 vs. Total Football Holland, 1990 vs. Maradona, 2014 vs. Messi) to a nation that shits its pants in a PK shootout against Paraguay. Isn't this the 1st time ever that Germany lost a PK shootout in the WC?
