KAZAN, Russia: The World and Confederation Cup champions of football Germany lost to South Korea after showing a poor performance in two to zero goal match. The Germans went home after losing to a South Korea side that had already lost to Sweden and Mexico.

The defending champions crashed out of the tournament after goals from Kim Young-Gwon and Son Heung-min. Mats Hummels said defending champions Germany's group stage exit from the World Cup finals for the first time since 1938 was a "bitter" shock for the team.

The Germans' 2-0 defeat to South Korea in Kazan on Wednesday means they finished bottom of Group F and sends Joachim Loew's side home after two defeats and a single victory.

"It is a really, really bitter evening for us," admitted Hummels, who squandered a late chance when he headed over.

"The situation is very difficult to put into words," he told ZDF.

"We did not put the ball in the net, even though we had plenty of opportunities, including myself in the 86th minute -- I have to score from chances like that.

"It is a very bitter evening for us and for all German football fans.

"We believed in it until the very end, we tried to shoot, but we just couldn't get the ball in.

"We had plenty of opportunities, we broke our necks trying out there today."

Germany qualified for Russia with a perfect record of ten wins, but Hummels said the last time the team played well was when they wrapped up qualification late last year.

"We put ourselves in this situation after the Mexican game," he admitted after the Germans lost their opener 1-0 to Mexico.

"The last game we delivered a good performance was in the autumn of 2017."
