Later on Saturday, two-time World Cup champions Uruguay battle reigning European champions Portugal as slim +180 chalk, while Sunday's action has Spain taking on host nation Russian Federation as a heavy -180 bet, and the surprising squad from Croatia clashing with Denmark as -120 favourites.
South Korea's players were unaware they had been eliminated from the World Cup when the final whistle went after their remarkable 2-0 win over Germany which also sent the champions crashing out of the tournament, goalkeeper Cho Hyun-woo said.
The 4-time champions needed to beat the unfancied Asians by two clear goals in their final group F match in Kazan to advance to the last 16.
In Russia, the Germans got off to a awful start with a 1-0 loss to Mexico, and their campaign ended on an even more bitter note after a stoppage-time victor from Toni Kroos against Sweden gave the false impression they had finally kick-started their tournament.
They remain unbeaten but, save Germany, there is no team to have disappointed more.
Cushions with what appeared to be a British flag design on them were also thrown in the direction of the team.
You've got to admit, though, they didn't deserve to reach the round of 16. How are we going to be unsafe to an opponent if we do not get our performance right? Modric has scored in two games out of three at Russian Federation 2018, while Eriksen's shoulders carry both Denmark's creative and goalscoring threat. I can not answer why that happened. I think we need to take action.More news: Uruguay not just focusing on Cristiano Ronaldo

The knockout stage of the 2018 World Cup is officially set.
It's a far cry from four years ago when the Germans handed host nation Brazil the most humiliating defeat in World Cup history on its way to winning the trophy for the first time since 1990. Maybe we invited the wrong players. They did not have speed in the game.
Given the defensive nature of both of these sides, this fixture is unlikely to be the most open we see in the knockout stages.
The country now joins a small but unlucky club of title defenders who crashed out of the first round at their next World Cup, a feat last achieved by Spain at the last World Cup in 2014. In any case, with a new generation of talented players at his disposal, he has what he needs to start rebuilding. Brandt was picked the World Cup ahead of Leroy Sane, the forward who had 10 goals and 15 assists in 27 Premier League appearances with Manchester City this season.
Andrés Guardado is a name and a face many might know for his existence in European football over the last few years.
