Jürgen Klopp suffered a shocking 1-0 home defeat to Greece in his Germany Nations League debut on Sunday, marking the first loss ever for the German national team against their opponents. Greece's substitute Dimitrios Kourbelis scored the decisive goal in the 74th minute with a deflected shot at the WWK Arena in Augsburg. Despite dominating possession with 77% according to Opta, Germany struggled to create clear chances against the Greek defense.

Karim Adeyemi forced a fine save early on, but Konstantinos Tzolakis was otherwise untested. Klopp acknowledged the result was part of the rebuilding process, stating he was responsible for the lineup and formation changes. Greece had a plan, and defender Jonathan Tah prevented another goal before Kourbelis stunned the home fans.

The result leaves Germany preparing to face Serbia in Munich before a reverse fixture against Greece next Sunday. Klopp emphasized continued squad rotation as he looks to rejuvenate the four-time World Cup winners.
