Supporters poured out of Guadalajara's Estadio Akron waving flags and singing after the final whistle, while thousands gathered at fan zones in Monterrey and Mexico City. The win guarantees Mexico a place in the last 32 and confirms the hosts as Group A leaders with six points from two matches, an important milestone for a team playing in front of home crowds.
The decisive moment came in the 50th minute when midfielder Luis Romo capitalised on a defensive mistake involving South Korean goalkeeper Kim Seung-gyu and defender Lee Gi-hyuk. Romo calmly converted into an empty net to score the only goal of the match. South Korea nearly levelled in the 87th minute, but goalkeeper Raúl Rangel produced a crucial save to preserve the lead.
