With that win they held their fate in their own hands, knowing victory over South Korea would guarantee them of a place in the last 16.
Mueller has scored 10 goals over two World Cups but was relegated to the bench after drawing a blank in Germany's first two matches in Russian Federation, with attacking midfielder Leon Goretzka selected instead. South Korea and Germany came in third and fourth, respectively, with three points apiece.
The goal was ruled out offside on field but confirmed by use of the Video Assistant Referee.
While the Germans were clumsy in front of goal, Kim Young-gwon and Son Heung-min scored late while their teammates defended superbly with last-minute tackles and hard collective work.
But he was caught out as a long ball left Tottenham forward Son with the simple task of walking the ball into the net to spark jubilant celebrations among the Asian side, even though their elimination had already been confirmed.
Lukaku & Hazard put Belgium on verge of last 16
The North-African side were dealt another blow ten minutes later, when Romelu Lukaku doubled the lead with a precise low finish. Tunisia captain Khazri grabbed their second goal just before the final whistle of their second defeat in Russian Federation .
"Ki and Park are very important to us, not just strategically but also mentally, they help the other players", Shin added.
Mexico's 2018 World Cup was dangerously close to coming to a heartbreaking ending.
That left Germany with 40 minutes to find the one goal they needed to qualify at Mexico's expense and Kroos, their lifesaver against Sweden, just fired wide nearly at the same time the Swedes went 2-0 up through Andreas Granqvist's penalty. The 1994 was a thriller, finishing 3-2 to Germany, but the 2002 match was all the more significant considering the fact that it was a semi final. This is how humiliating defeat was for the Germans: in the last four World Cups they have reached at least the semi-final.
"I didn't think Thomas Muller had been that convincing in the first two matches and I wanted to make a point there [by dropping him]".
Their reward for reaching the semis was a match against the always unsafe Germany, who had cruised through the tournament up until that point. "We need a couple of hours to see things clearly".
