While there may be very little for the Koreans to play for, if recent form is anything to go by, they could well provide stern opposition for their European counterparts.
Put simply, Spain's defence of the World Cup two years ago was nothing short of disastrous.
Having won the three major tournaments that had preceded it, all eyes were on Vicente del Bosque's men in Brazil to see if they could make it four in a row.
However, the 5-1 hammering at the hands of the Netherlands set the tone, while a 2-0 defeat to Chile sealed a group-stage exit.
In terms of the Euros, the Spanish have already made history by becoming the first nation to retain the trophy four years ago. The task now is to extend that run.

Not since they played the role of World Cup co-hosts 16 years ago has there been so much optimism around the South Korean national side.
Back then, the energetic men in red caused a big impression on the watching world as they reached the semi-finals, incidentally knocking Spain out on penalties along the way.
Considering the enthusiasm that swept the country during that time, the fact that head coach Uli Stielike has overseen a near return to those levels over the last couple of years highlights how positive a job he has done.
The reason for this is simple - good results. Since losing to Australia in the final of the AFC Asian Cup in January of 2015, South Korea have tasted defeat in none of their 16 outings.
Thirteen of those matches have ended in victories, including the last nine in a row. During that sequence, Stielike's men have scored 29 goals and conceded none.
The boss has selected just 20 players for the game against Spain and the next friendly with the Czech Republic. The thinking behind that decision is that he does not want players travelling long distances only to not get any minutes on the pitch.

None of Spain's representatives from the Madrid duo, who contested the Champions League final, featured against Bosnia and that is expected to also be the case in this game.
Del Bosque should rotate his starting lineup, though, with the Barcelona players tipped to return.
Spain possible starting lineup:
De Gea; Alba, Pique, San Jose, Bellerin; Bruno, Busquets, Thiago, Fabregas, Silva; Morata
South Korea possible starting lineup:
Sung-ryong; Tae-hwi, Jeong-ho, Hyun-soo, Kee-hee; Sung-yueng, Kook-young, Tae-hee, Jae-sung, Heung-min; Dong-won
Head To Head
South Korea are yet to beat Spain over 90 minutes, but as already mentioned, they did get the better of them on penalties in 2002.
Spain have won three meetings, including the most recent clash in 2012, which ended 4-1 in favour of the Europeans.
We say: Spain 2-1 South Korea
The South Koreans are known for having great stamina so they are bound to give Spain a decent game. With a number of changes to the starting lineup, it could be a disjointed display from Del Bosque's charges, with a draw being the most likely outcome.
