After the country’s disappointing World Cup exit in the round of 16, Matthaus argued that the national team’s problems extend beyond the head coach.
The former captain called for sweeping reforms within the DFB, insisting the federation must undergo significant changes to avoid repeating recent failures.
"Every stone must be turned over and everyone at the DFB must question themselves," Matthaus told Sky Sport.
"It's not just the national coach, but all DFB officials must take responsibility for the fact that Germany has once again failed so ingloriously at the World Cup. The first big mistake was the design of Nagelsmann's extension almost a year ago."
