South Korea were pelted with toffees, a Korean insult, when they returned winless from Brazil 2014 and although they again leave early, after defeats to Mexico and Sweden, they finished above Germany on goal difference in Group F. South Korea's Son Heung-Min added another goal a few minutes later in one of the most shocking results in soccer history, officially eliminating defending champion Germany.
The pattern of the first half was as expected, with Germany trying to set the tempo and the South Koreans looking to hit them on the break.
The South Koreans, who had no idea of the score in the other match, rejoiced as if having won the tournament, while 11 German players hoped the ground would swallow them.
Like Neuer, Thomas Muller broke through the ranks in Germany's national team at World Cup 2010, although the Bayern Munich forward was benched for the crunch clash with South Korea, and the 28-year-old admitted the squad were embarrassed by their displays.
Kim Young-gwon's 92nd-minute goal, awarded after a video assistant referee decision, left four-time winners Germany on the brink of elimination.

With no shortage of chances, the Germans simply could not find the composure to score - most notably, and with pressure rising to breaking point - Mats Hummels, who missed a free header in the 87th minute.
Victory will confirm Brazil as group winners, but coach Tite is warning that under-fire superstar Neymar can not be expected to win the World Cup on his own and is not yet at full fitness. Costa Rica finally got their first goal of the World Cup in the second half when Kendall Watson rose highest to head home Joel Campbell's cross.
We repeat: the team which overcame Lionel Messi's Argentina in the final, the group of ice-veined warriors which dismantled Brazil 7-1, is going home.
Since the last World Cup, they have lost Philipp Lahm, Per Mertesacker, Miroslav Klose and Bastian Schweinsteiger, while the likes of Sami Khedira and Thomas Muller no longer look to be at their best.
"Korea! Korea!" chanted fans in a Mexico City bar, leaping into the air and embracing when the Asian side scored a stoppage-time, VAR-assisted goal, and then a late second to seal the reigning champions' humiliating exit - and allow Mexico to squeak through to the last 16.
"We need to analyse this and it has to be said very clearly that we just do not deserve it".
