South Korea ended its final World Cup warmup with a 5-0 rout of Trinidad and Tobago on the 31st in Provo, Utah, and the result was matched by an eye-catching debut-level display from Lee Ki-hyeok. The defender played the full 90 minutes, completed 69 of 73 passes and helped Hong Myung-bo's side leave no doubt about the value of the system it used.
That is why the match drew attention beyond the scoreline. With the 2026 FIFA World Cup squad already taking shape, South Korea needed a clean performance to test both its shape and its fringe players, and Lee emerged as one of the clearest winners. Hong had unexpectedly named him in the final squad, and the 24-year-old from Gangwon responded by showing the calm and range that got him there in the first place.
Hong set South Korea up in a modified 3-4-2-1, with Lee, Cho You-min and Lee Han-beom forming the back three, Kim Jin-kyu and Baek Seung-ho in midfield, Jens Castrof and Kim Moon-hwan as wing-backs, Son Heung-min at central striker, and Bae Jun-ho and Lee Dong-gyeong behind him. The structure worked from the start. Son scored multiple goals, Cho Gue-sung added multiple goals of his own, and Hwang Hee-chan finished the scoring as South Korea produced one of its most complete attacking performances of the build-up.
Lee's numbers explain why Hong spoke so highly of him afterward. He finished with a 95% passing rate, a 92% success rate in the opponent's half and a perfect 100% in his own half. He also added one successful tackle, two clearances and two cover actions while operating as the left stopper, and Hong called the performance excellent even though it was essentially his first A-match appearance. The coach also described Lee as a versatile player who can operate both in midfield and at full-back.
That matters because South Korea has not always looked this free. Hong had previously leaned on a rigid defensive approach that blunted the attack, but the back-three setup against Trinidad and Tobago delivered something different: control without caution, width without waste. It was the kind of performance that can only help a player like Lee, who had no link to the national setup until this season and earned his place through his form for Gangwon after making his debut for the Seong In team in Hong Kong last summer.
The larger question now is not whether South Korea passed this test. It is whether Lee's 90 minutes in Utah were enough to turn a surprise call-up into a real World Cup role. Hong has already shown he values flexibility, and if he keeps that preference, Lee may have done more than survive a trial run. He may have forced himself into the conversation before the tournament begins.
