World Cup Day 1: The biggest moments from opening day

Mexico gave the 2026 World Cup its first statement result, beating South Africa 2-0 in Mexico City before South Korea followed with a 2-1 comeback win over Czechia in Guadalajara. The two results left Group A with an immediate split: Mexico and South Korea on three points, South Africa and Czechia already chasing. It was also the first matchday of the expanded 48-team format, a 104-game tournament spread across Canada, Mexico and the United States. That scale was visible from the first day: one host-nation spectacle at the Azteca, one tighter late-night group match in Guadalajara, and the early sense that this World Cup will be judged as much by logistics as by football.

Mexico Dominates Opening Match

Julián Quiñones scored the tournament’s first goal after nine minutes, giving Mexico the clean start a host nation needs in an opener. Raúl Jiménez added the second in the 67th minute, a major personal moment after years of injury recovery and a long wait for his first World Cup goal. The goal also moved Jiménez level with Jared Borgetti for second place on Mexico’s all-time scoring list, behind Javier “Chicharito” Hernández. The review is simple: Mexico were not flawless, but they were sharper in both boxes, and on opening day that mattered more than style.

Three Reds Change The Tone

The opener turned rough after halftime, with South Africa losing Sphephelo Sithole and Themba Zwane to red cards before Mexico defender César Montes was sent off in stoppage time. That made it the first World Cup opening match to produce three red cards, and the most dismissals in a World Cup game since 2006. South Africa finished with nine men, which made any comeback unrealistic even before Jiménez’s goal settled the match. The football note for Mexico is positive, but the caution is clear: discipline and match control became part of the tournament story before the first day was over.

South Korea's Comeback Victory

South Korea’s win had a different shape: slower start, second-half problem, fast answer. Czech captain Ladislav Krejčí scored with a header in the 59th minute, but Hwang In-beom equalized eight minutes later and then supplied the cross for Oh Hyeon-gyu’s winner in the 80th minute. It was South Korea’s first opening-match World Cup win since 2010, and it continued a recent pattern of Korean success against European opponents at the tournament. Son Heung-min did not score, but South Korea had enough control and late energy to turn a difficult match into three points.

Krejčí’s Header, Oh’s Answer

Czechia’s best route came through set pieces, and Krejčí’s goal showed why that remains the team’s cleanest attacking weapon. South Korea were better in open play, with Hwang carrying the game from midfield and Lee Kang-in adding creativity in the channels. The Czechs thought they had a second set-piece goal when Tomáš Souček headed in late, but the effort was ruled out for offside. The match review favors Korea on balance: Czechia had danger moments, but South Korea had the better rhythm, better chances and the player of the match in Hwang.

Beyond the Pitch: Logistics and Fan Experience

This World Cup is bigger by design: 48 nations, 104 matches and 16 host cities across three countries. That gives more teams a path into the tournament, but it also stretches travel, scheduling and local operations across a much wider map than previous editions. Group A now has a clear early pressure point, with Mexico and South Korea able to approach their next match from strength while South Africa and Czechia need points quickly. The forward implication is already obvious: Mexico vs. South Korea can become the early control match in the group, while Czechia vs. South Africa may carry knockout-stage consequences after only one round of games.

Crowds, Prices And Police

The day was not only about the games. The Mexico City ceremony brought Shakira, Burna Boy, Alejandro Fernández, Belinda, Danny Ocean, J Balvin, Lila Downs, Los Ángeles Azules, Maná and Tyla into the opening show, giving the event a strong local and global entertainment frame before kickoff. Outside the Azteca, however, unrest near gate eight included rocks, bottles and petrol bombs thrown at police, with authorities saying the situation was brought under control and kickoff went ahead. In Guadalajara, the reported attendance for South Korea-Czechia was 44,985, though visible empty seats triggered questions about pricing and atmosphere. The first-day risk for organizers is now plain: the football product is strong, but crowd management, affordability and security will remain part of the tournament review.
