The first realistic task that the Korean national team will face in this World Cup is ‘adaptation to high altitudes.’ Ahead of the competition, the national team played a final warm-up match against El Salvador in Salt Lake City, Utah, USA, testing its ability to adapt to the alpine environment over 1,300 meters above sea level. This is a very strategic choice considering that Guadalajara, Mexico, where the group stage of the finals will be held, is located at an altitude of more than 1,500 meters above sea level. In fact, Mexico's overwhelming performance came from using this high-altitude environment as their home, and managing their stamina in an environment with low air density will be a key variable in getting through the group stage. In order to overcome these adverse geographical conditions, Hong Myung-bo is on a critical test where he must maximize tactical flexibility and achieve the best performance through thorough data-based condition management.

Looking at the group stage bracket, Korea will face the hosts Mexico and South Africa in turn, starting with the first match against the Czech Republic. In particular, the second match against Mexico, ranked 15th in the FIFA rankings and backed by enthusiastic support from home fans, is expected to be the biggest match of this group stage. Mexico already took the lead in the tournament, showing off its powerful firepower from the first game, led by threatening attackers like Julian Quiñones. The match against Mexico will be a difficult challenge as we will have to experience from the opponent's perspective the weight of the home advantage we enjoyed during the 2002 Korea-Japan World Cup. In addition to the rivalry between the two teams, who have faced each other several times on the World Cup stage in the past, how to effectively block Mexico's quick offense and defense transition will be a measure of coach Hong Myung-bo's tactical capabilities.

This tournament, which was expanded to 48 countries, also brought about significant changes in the method of advancing to the tournament. With three countries playing in a group, the top teams in each group advance to the round of 32, creating more complex situations than before. If you make it to first place in your group, you can expect a relatively easy matchup, but if you fall to second or third place in your group, a thorny path awaits you as you have to face the strong players of Group B, E, or G. In this situation, the national team needs detailed management that goes beyond scoring three points in each game and also takes into account goal difference management. In particular, the final game of the group stage, against South Africa, coincides with the symbolic date of the Korean War Memorial, so it will be a game that requires more mental armor and responsibility for the results from the players than ever before.

In modern soccer, the World Cup is more than just a sporting event, it is also a huge stage where political dynamics between countries are projected. As the past confrontation between the United States and Iran showed, the 90 minutes on the pitch can sometimes become a symbolic chapter that encapsulates the tension between the two countries. Fortunately, in this group stage, South Korea faces opponents who must compete purely on soccer skills rather than on political influence. Nevertheless, Mexico's strong home advantage and high altitude environment pose more difficult obstacles than any opponent. The national team has the task of not being swayed by these external variables and combining the experience of key players, including Son Heung-min, with coach Hong Myung-bo's seasoned resourcefulness to provide a moment of joy to the entire nation once again in the summer of 2026.
