Co-hosts Mexico became the first nation to qualify for the knockout stages of the 2026 World Cup with a narrow win over South Korea in Guadalajara yesterday night, Thursday, June 18.

Mexico midfielder Luis Romo was in the right place at the right time to tap into an empty net after goalkeeper Kim Seung-gyu spilled the ball following a collision with his team-mate Lee Gi-hyuk in the 50th minute.

South Korea's best chance came in the 87th minute when Cho Gue-sung's close-range header was saved by Raul Rangel and the Mexico keeper was able to keep out Yang Hyun-jun's follow-up.

Earlier, captain Son Heung-min's had chipped Rangel before his effort was cleared off the line by Edson Alvarez although the former Tottenham forward was flagged offside.

Backed by a boisterous home support who had booed their team at half-time following a toothless first half, Mexico almost added a second in the 75th minute but Raul Jimenez's effort from a tight angle was saved.

Substitute Obed Vargas also forced Kim into a fine diving save late on with a driven strike.

The result continued Mexico's 100% start at the World Cup and confirmed Javier Aguirre's side will advance as Group A winners.

That means the co-hosts will be in Mexico City for both their last-32 and potential last-16 tie, where they could face England if Thomas Tuchel's side win their group and first knockout match.

Despite their defeat, South Korea remain in a good position to also advance thanks to their opening-day win over Czech Republic.

They face South Africa next on Thursday (02:00 BST) in Monterrey. Mexico take on Czech Republic in their final group game at the same time Mexico City. (BBC)
