Joachim Low will consider his future as Germany head coach after the defending World Cup champions suffered a shock group-stage elimination.
Germany were again disappointing, and after a number of warning shots, South Korea did take the lead as Kim Young-gwon turned the ball home from close range, with VAR reversing a decision to rule the goal out for offside.
The four-time champions lost to South Korea 2-0 on Wednesday, allowing a pair of injury-time goals while knowing a 1-0 victory would have been enough to advance because of the result in the other group match.
2018 - Germany | a single-goal loss to Mexico wasn't the desired start but a last gasp Kroos goal seemed to get things back on track as they beat Sweden 2-1.
And Loew, the 58-year-old who guided Germany to the world crown in Brazil four years ago, admitted he now needs time to decide whether his 12-year reign will continue - despite signing a new four-year contact in May.
Meanwhile, Germany's exit from the World Cup had Twitter buzzing.
"We believe there will be a transition that will take place after the World Cup, regardless of the outcome of the tournament, and no one is better equipped to handle that than Jogi Loew". South Korea were also eliminated despite the victory. We will analyse what went wrong and carry on working as we always did.

If England win, the star strikers looking to take them down are Messi, Ronaldo, Suarez, Mbappe, Neymar and Javier Hernandez. England have not won a knockout game at a major tournament in 12 years, and that includes defeat against Iceland.
South Korea will be one of the favourites to win the tournament, which begins in early January and runs until early February - which is a blow for Tottenham Hotspur.
The result sparked huge celebrations among the legions of Mexican fans in Russian Federation, and also back home in Mexico City, not least when locals mobbed the South Korean embassy and hoisted the ambassador onto their shoulders, before marching him around in thanks for his team's heroics in helping Mexico into the last 16. But the team never really seemed to recover from its opening 1-0 loss to Mexico.
However, even with Ozil's restoration, Germany looked sapped of craft and ingenuity in the final third.
From 30 yards out, it should have been fodder for World Cup-winning Neuer, but he fumbled Jung's dipping drive Neuer and scrambled desperately to clear.
"We were playing for the Korean people", said Cho, a cult figure at home for his ostentatious, orange bouffant.
But a 2-0 defeat to South Korea condemned Germany to finish bottom of Group F, and many rival fans enjoying the nation's failures.
"South Korea has players who can execute fast breaks, we will try to adapt", Loew said.
