In a historic win, Greece hands Klopp his first home defeat.

Despite the German team's dominance in the match, with around 80 percent possession in the first half, they failed to convert their superiority into goals.

Greece exploited gaps in the German defense during the second half, sealing the match with a low shot from Korbelis that changed direction and found the net.

Klopp: The result is part of the process

With this victory, Klopp continues his quest for his first win with the German national team, having taken charge in July after the team's early exit from the World Cup.

After the match, Klopp said: "I could have accepted not winning, but we cannot lose a match like this. We have been together for a week, and we are all integrating, which takes time."

He added: "The result is not satisfactory, but it is an integral part of the process."
