Korea broke through early — Eom Ji-sung's 15th-minute opener came out of the wide, overloaded build-up play that defined the whole match — then had to see out a first half in which Paraguay had their own spells of pressure. Hwang In-beom's rotation through three different midfield roles kept Korea's structure fluid enough that Paraguay never settled on a clear picture to press against, and substitute Oh Hyun-gyu doubled the lead in the 75th minute, finishing a Lee Kang-in assist that came from exactly the kind of half-space drop that had been softening Paraguay's right side all game. A comfortable 2-0 in a fixture Korea's staff had specifically scouted to exploit.

Korea lined up in a 3-4-3 against Paraguay's 4-2-3-1, but the name on the sheet mattered less than the fluidity of the roles — the build-up and defensive shapes reshaped between phases, and that fluidity is where the goals came from.

Hwang cycled through three roles inside one match. As the pivot he sat in front of the back line and distributed; he dropped into the back line to form a build shape and add an option; and at the right moments he broke the line to thicken the midfield and join the attack. A holding midfielder rotating through several roles is the on-pitch reading of the principle that the player with the most touches should carry the most variation.

Every time Lee Kang-in dropped to help the build, a chain reaction freed the right: Paraguay tracked him, their marking shifted, and space opened out wide. Lee Dong-gyeong and Kim Moon-hwan also swapped roles to scramble the marking references. The pay-off came late — Lee Kang-in's creativity produced the assist for substitute Oh Hyun-gyu's 75' goal, the moment that killed the game off at 2-0.

The structure was the familiar one: overload one side to lean Paraguay's block across, then attack the space that opened. This time it converted early — Eom Ji-sung's 15' opener came out of Korea's wide, penetrative play down the flanks, exactly the isolation the overload is designed to create. Paraguay actually had more shots (10 to 8), but Korea's were the higher-quality ones (3 on target to 1), and the two that mattered came from the designed pattern.

The staff's pre-match scouting on Paraguay flagged two specific weaknesses that the game plan was built to attack. First, in build-up: Paraguay's press doesn't commit to the ball-carrying centre-back — it's aimed one line higher, at Korea's pivot — which tends to produce Paraguayan back-passes rather than clean recoveries when that midfield press is beaten. Second, in their own defensive shape: Paraguay's front press (a 5-2-3 look, winger stepping to whichever centre-back holds the ball, full-back marked man-to-man by the opposite wing-back) leaves its two remaining centre-backs to cover the width behind it — and when a wing-back is instead pulled into a deeper, cautious block, the space out past him opens for exactly the kind of underlap Korea's full-back and winger combinations are built to exploit. Both patterns lined up with what actually happened: Hwang In-beom dropping to receive past the first press wave, and Eom Ji-sung's opener arriving from the flank the scouting had marked as the softest point of Paraguay's back line.

The multi-positionality was real — Hwang In-beom's three roles, Lee Kang-in's self-limitation, the Lee Dong-gyeong / Kim Moon-hwan switch — and here it did what it is supposed to do: give Paraguay's 4-2-3-1 no stable reference point to mark, then convert. But the roles weren't improvised; they were built against a specific scouting picture of where Paraguay's structure gives way. One holding-midfielder rotation, one exploited flank, and one moment of individual creativity from Lee Kang-in were enough to turn a scouted weakness into two goals.
