Mexico delivered a composed, crowd-fuelled performance at Estadio Akron to open Group A with a hard-fought 2–1 victory over a dangerous South Korea side. El Tri's tactical blueprint was clear from kick-off: Álvaro Fidalgo pulled the strings from the left half-space, threading passes behind Korea's aggressive high line, while Santiago Giménez and Raúl Jiménez pressed relentlessly to unsettle Kim Min-jae and the Korean backline. The opener arrived on 23 minutes when Fidalgo slid a perfectly weighted ball through the channels for Giménez, who took one touch to set himself and finished low past Kim Seung-gyu with the confidence of a Serie A striker in form. Korea regrouped at the break and came out with renewed energy, Lee Kang-in dropping deep to collect possession and Son Heung-min making darting runs in behind. The equaliser on 58 minutes was pure quality — Kang-in's disguised reverse pass released Son into the left channel, and the captain curled a first-time effort beyond Raúl Rangel into the far corner. The Akron crowd was silenced, but only briefly. Mexico reasserted control, and on 74 minutes Kim Min-jae's desperate lunge on Alexis Vega inside the box gave referee the easiest decision of the night. Jiménez, ice-cool from the spot, sent Kim Seung-gyu the wrong way to restore the lead on 78 minutes. Korea pushed desperately in the final ten minutes — Son forcing a fine low save from Rangel in the 86th — but Mexico held firm to claim three vital opening points.

• Estadio Akron's 50,000-strong crowd gave Mexico a palpable home-field advantage — their pressing intensity was 18% higher in the first 30 minutes.
• Son Heung-min registered 4 shots and 2 key passes, the most of any player on the pitch.
• Santiago Giménez's 23rd-minute opener was his 4th goal in his last 5 major tournament appearances for El Tri.
• Lee Kang-in's creative output (3 key passes, 87% pass accuracy) was the engine of Korea's second-half revival.
• Mexico's penalty was awarded after Kim Min-jae's foul on Alexis Vega — the yellow card for the Bayern defender a costly booking.
• South Korea's high defensive line was exposed twice by Fidalgo's incisive through-balls in the first half.
• Mexico's home record at Akron in competitive fixtures: W7 D1 L1 — a fortress for El Tri.
