Former Germany international Michael Ballack has questioned the German Football Federation's decision to reward Joachim Low with a new contract shortly before their World Cup campaign.
Long-serving boss Low extended his deal with Die Mannschaft less than a month before the competition started, taking him through until the end of Qatar 2020.
The move appears to have backfired, however, as a poor showing in Russia saw Germany fall at the first hurdle at the showpiece competition for the first time since 1938, culminating in a humiliating 2-0 loss to South Korea on Wednesday.
Ballack is unsure why Low extended his terms before the tournament, with Sky Sports News quoting him as saying: "The result from Wednesday in Kazan was a total shock for me.
"After a European Championship or World Cup, you can judge the work that has been done in the previous two years. Friendlies and tournament qualifiers for a footballing nation like Germany are not proper indicators of the state of our team.
"For this reason, it was unnecessary to give Joachim Low a four-year contract extension just four weeks before the World Cup started. Whether Low is still the right person to manage this team, I cannot say.
"There is no explanation as to how a team with this quality can end at the bottom of this group. How can this group of players struggle with all these basics of football?"
Germany's next scheduled match is a UEFA Nations League clash against France in early September.
