South Korea
Taekwondo is a martial art native to South Korea. In fact, it is the nation’s national sport and is characterized by various kicking actions, most notably head-height kicks. This must be why the country took to soccer so easily. This is because, as per a 2021 poll, soccer is the most popular sport in the country.
This was evident at the 2002 tournament they hosted, with thousands of fans filling stadiums, and even more, they filled parks outside with fans to watch their matches. This was also their strongest finish, where they made the semi-finals. All of their players were excused from military service because of this feat.
