Tomáš Souček frames South Korea’s 1,670-meter Guadalajara test
tomáš souček is in the mix as South Korea and Czechia meet in Guadalajara, where the World Cup 2026 match is being played about 1,670 meters above sea level. South Korea had an altitude warm-up period in Utah; Czechia did not.
Guadalajara at 1,670 meters
The kickoff came at 8pm local time, 12pm AEST, 3am BST and 10pm EDT in Zapopan, where conditions were around 27C and falling, with wisps of rain drifting around. Those numbers matter because this is the kind of opening-round game that often tilts toward caution, and both sides would have taken a draw.
Guadalajara is not just a different city from Utah. It is a different test. The match sat roughly 1,670 meters, or 5,480 feet, above sea level, and that is the immediate physical edge South Korea had already started to handle before kickoff.
Hong Myung-bo’s shape shift
Hong Myung-bo and João Aroso moved South Korea from a proactive 4-4-2 to a more conservative 3-4-3, with Kim Min-jae pivotal in holding the back three together. Seol Young-woo worked at right wingback and Lee Tae-seok at left wingback, while Hwang In-beom remained the player knitting the midfield together.
That structure gave South Korea a way to absorb the altitude without giving up too much control. Lee Kang-in and Son Heung-min were identified as the main sources of individual brilliance further forward, so the shape put the responsibility on the back line and midfield to keep the game stable long enough for those two to matter.
Czechia’s late route
Czechia reached this point much later than South Korea, finishing the first Uefa group phase behind Croatia and then going through Playoff Path D. They beat the Republic of Ireland and Denmark on penalties after 2-2 draws, then followed with a 2-1 win over Kosovo in Prague and a 3-1 win over Guatemala in New Jersey.
That run left them as the 40th of 42 nations to qualify, which is why the altitude gap matters here more than it would in a typical group match. South Korea had a warm-up block in Utah; Czechia arrived without that acclimatisation runway, and Vladimir Coufal’s side had to manage the conditions on the day instead of preparing through them.
Amin Omar handled the match, but the real dividing line was the environment above Zapopan. South Korea entered with altitude work behind them and a shape built for control, while Czechia came in on the back of a late qualification surge and a shorter preparation window.
