Hong Myung-bo made a notable mid-cycle switch, abandoning the 4-2-3-1 used throughout Asian qualifying in favour of a 3-4-3 with a back three — a shape he ran across three consecutive pre-tournament friendlies. As of June 5, he has framed the shift as deliberate adaptability, noting that relying on a single tactic in World Cups is difficult. Six centre-back options in the squad signal how deliberately the structure was resourced. Reports suggest Park Yong-woo's absence influenced the decision, though that reading is editorial inference rather than a direct managerial admission. South Korea's qualifying defensive record was among the AFC's best: 8 goals conceded, 92 shots allowed.

Son Heung-min is the unconditional focal point. The 33-year-old captain has 56 international goals and contributed 10 in Asian qualifying — joint second-highest. His club season at Los Angeles FC produced only two goals before the tournament, though he scored twice in the Trinidad and Tobago friendly and was managed to the bench against El Salvador on June 3. Whether he operates at his 2022 Qatar level is the closest thing South Korea has to a single-factor tournament determinant.

Lee Kang-in, 25, provides the primary creative infrastructure: 5 goals and 6 assists in qualifying with 37 chances created. Kim Min-jae anchors the back line with a 74.4% aerial duel success rate in qualifying, bringing Bundesliga physicality to Hong's new three-man defence.

Group A — Czech Republic, South Africa, Mexico — is played in Guadalajara at 1,571 metres. Mexico's co-host status brings a partisan crowd to every fixture at that venue. A realistic knockout-round path runs through South Africa and Czech Republic, with the Mexico match likely deciding second place. Advancing from the group is achievable and probably the most likely single outcome; altitude and midfield depth concerns make sustaining high-intensity pressing across three matches harder to execute than the qualifying template suggests.

South Korea's ceiling here is the round of 16, or a quarter-final if Son rediscovers top form and the bracket opens. Their floor is a defensively disciplined side that keeps scores tight but struggles to generate chances against organised opposition without the captain at his best. The 3-4-3 switch cuts both ways — potentially harder to prepare against than the familiar qualifying shape, but also still embedding in real time. South Korea tend to exceed their paper quality when early results are clean and key individuals click; this draw gives them a credible opportunity to find out whether that pattern holds.
