They are arguably the most accomplished Asian football team, but South Korea face a tough task if they are to progress from the group phase at the 2022 World Cup.
The squad is coached by Paulo Bento, the former Portugal manager who was charged with leading the national team to Qatar when he replaced Shin Tae-yong, whose time was up after the 2018 tournament.
Bento's career includes coaching Sporting Lisbon and leading Portugal to the semi-finals of Euro 2012, but he was later sacked.
The team is recognised by Fifa as Korea Republic.
South Korea World Cup 2022 squad
Each country’s final World Cup squad of 23-26 players must be submitted to Fifa by November 13. The replacement of injured or Covid-19 positive players is allowed up to 24 hours before a team’s first match. This year the World Cup will run from November 20 to December 18.
Who are likely to be the star names in the squad?
Dubbed the most under-rated striker on the planet, Tottenham Hotspur forward Son Heung-min is the highlight of the squad.
In 2018, he was pivotal to South Korea stunning Germany, knocking them out of the group stage in Russia.
The key question is whether he can elevate his explosive Premier League form to the biggest stage of all.
However, required surgery on a fractured eye socket puts his World Cup with South Korea in serious jeopardy. The Tottenham Hotspur forward was injured during his team's Champions League win at Marseille.

What is South Korea's World Cup record?
South Korea made their World Cup debut in 1954 and have competed in the most editions of any Asian country.
They have taken part in nine consecutive showpieces, finishing in the group stage every time except for in 2010 when they made the Round of 16 and in 2002 when they finished fourth place, their best result.
Their form coming into Qatar is a mixed bag, with this year's international friendlies seeing them draw to Costa Rica and Paraguay, beat Egypt 4-1 and Chile 2-0, and defeats to Brazil and UAE.
South Korea are currently 250/1 to win the World Cup 2022.
