A wild opener in Mexico City and a sharp South Korean rally in Guadalajara gave the expanded tournament an immediate identity. Canada now steps into a stage already buzzing with shocks, emotion, and history.
The 2026 World Cup opened like a tournament determined to make a statement. Two Group A matches started the 39-day, 104-game event across Canada, the United States, and Mexico, and both games delivered enough chaos to suggest that the new 48-team format will create plenty of unpredictability. For Canada, the message was simple: by the time the hosts play their first match, the tone of the tournament may already be set.
A Feverish Start in Mexico City
The first whistle came at the Estadio Azteca, where more than 80,000 fans filled the seats for a ceremony that included performances by Shakira and the band Maná. The atmosphere was celebratory, but the match between Mexico and South Africa quickly turned into a tense and often messy contest.
Mexico struck first in the ninth minute after Erik Lira stole the ball from a South African defender trying to build from the back. Julián Quiñones finished calmly, sliding the ball through goalkeeper Ronwen Williams to score the tournament’s first goal. Later, Raúl Jiménez added a second goal that carried extra weight: the forward, who suffered a fractured skull in a 2020 collision while playing for Wolverhampton, headed in what became his first World Cup goal and reacted with visible emotion.
The match will also be remembered for its discipline problems. Brazilian referee Wilton Sampaio issued three red cards, the most ever in a World Cup opener and the first time a World Cup match had produced three dismissals in 20 years. South Africa lost Sphephelo Sithole before halftime and Themba Zwane after a video review caught a swipe at Roberto Alvarado. Mexico later went down to 10 men as well when César Montes was sent off for stopping a South African break. All three players will miss the next group match.
For Mexico, the result carried real significance. Javier Aguirre’s team earned its first victory in a World Cup opener after five defeats and two draws, and it did so while relying heavily on 17-year-old midfielder Gilberto Mora, one of the youngest standout names in the field. The 2-0 win gave the hosts a strong opening and a rare sense of control in a World Cup setting.
South Korea Showed the Composure of a Contender
The second match of the night in Guadalajara offered a very different mood. South Korea, ranked 25th in the world, fell behind Czechia, ranked 38th, before recovering to win 2-1 at Estadio Akron in front of a crowd that never quite filled the stadium but still saw a high-quality finish to the evening.
The early stages were flat enough that both sides drew boos at halftime, but Czechia found the first breakthrough in the 59th minute. Captain Ladislav Krejčí rose to meet a long throw and headed in the opener, staying true to the set-piece strength that had carried Czechia through qualifying. South Korea answered with the most polished move of the day. Eight minutes later, Lee Kang-in delivered the pass that opened the defense, Hwang In-beom used a sharp feint to create space, and the equalizer curled into the corner after a 25-pass buildup that ranked among the longest goal sequences in World Cup history.
The match still had another swing. Tomáš Souček appeared to put Czechia back in front in the 77th minute, but an offside call confirmed by review erased the goal. Three minutes later, South Korea punished the mistake. Substitute Oh Hyeon-gyu, who later said a 38-degree fever had nearly kept him out of the lineup, finished Hwang’s low cross for the winner. Goalkeeper Kim Seung-gyu then preserved the result with a late diving save.
South Korea ended with 15 shots to Czechia’s eight and left the impression of a team with real knockout-stage potential. The performance also added to Son Heung-min’s legacy, as he became only the second player to appear in four World Cups for South Korea, joining head coach Hong Myung-bo.
What the Results Mean Before Canada Plays
After one day, Group A already looks crowded at the top. Mexico and South Korea share first place with three points each, with the hosts ahead on goal difference. South Africa and Czechia now face quick corrections, suspension concerns, and pressure to respond immediately.
| Match | Winner | Deciding Moment | Main Takeaway |
|---|---|---|---|
| Mexico vs. South Africa | Mexico, 2-0 | Early steal and late emotional header | History, discipline issues, and a strong host start |
| South Korea vs. Czechia | South Korea, 2-1 | 25-pass equalizer and late substitute winner | Poise under pressure and dark-horse potential |
For Canada, Thursday’s action served as a preview of the scale and intensity that comes with hosting. The Canadian men begin their campaign Friday at a sold-out BMO Field in Toronto against Bosnia and Herzegovina, marking the first men’s World Cup match ever played on Canadian soil. Jesse Marsch’s squad is in Group B with Bosnia, Qatar, and Switzerland, and the rest of its group matches will take place at BC Place in Vancouver.
That backdrop gives Canada a rare opening-day advantage: a chance to watch, adjust, and walk into its debut with a better sense of how quickly the tournament can shift. If the first two matches are any guide, the World Cup is set to be fast, emotional, and difficult to predict. Mexico got a milestone win, South Korea made a statement, and Canada now inherits a stage already charged with momentum.
Quick Takeaways From Day One
- Mexico earned its first-ever World Cup opener victory and did it with a clean sheet.
- Three red cards made the Mexico-South Africa match the most volatile opener in tournament history.
- South Korea turned a poor start into a comeback win and looked organized enough to trouble stronger teams.
- Canada’s debut now arrives with the tournament already offering major storylines.
For a World Cup that already feels larger, louder, and less predictable than any before it, opening day delivered exactly the kind of signal organizers wanted and opponents probably feared. Canada’s turn comes next, and it enters with the benefit of having seen the standard set in full view.
