Mexico delivered a ruthless home win, South Korea proved its fight, and Group A instantly looked volatile in the first full show of the expanded tournament.
The 2026 World Cup began with the kind of pace and disorder that makes a long tournament feel alive from the first whistle. Two Group A matches opened the 39-day event, and both games offered a clear warning to the rest of the field: this version of the competition will reward teams that stay composed when the noise rises and the margins shrink.
For Canada, which has not yet entered the stage, the first day functioned as both preview and pressure test. The co-hosts saw one rival seize control at home, another rally with discipline, and a tournament favorite promising little room for error. That is a useful signal before the Canadian team takes its own turn in front of a home crowd.
Mexico Turn A Home Opener Into A Statement
The night started in Mexico City, where the Estadio Azteca was packed with more than 80,000 fans and framed by an opening ceremony featuring Shakira and Maná. Against that backdrop, Mexico produced the kind of performance that home supporters had been waiting to see.
South Africa tried to build from the back, but that plan collapsed early. Erik Lira stepped in to win the ball in the ninth minute, and Julián Quiñones finished the move by slipping a shot through Ronwen Williams. That goal gave the tournament its first defining moment and put Mexico in command before the match had settled.
The second goal carried even more emotional weight. Raúl Jiménez, whose career was almost derailed by the skull fracture he suffered in 2020, climbed to meet a cross and scored his first World Cup goal. The celebration was raw and immediate, with the striker leaving the pitch in tears after reaching a milestone that had once looked impossible.
Then came the part that will dominate the memory of the match for years.
- Brazilian referee Wilton Sampaio issued three red cards, the most ever in a World Cup opener.
- South Africa lost Sphephelo Sithole before halftime.
- Themba Zwane was later sent off after video review captured a strike to Roberto Alvarado’s face.
- Mexico’s César Montes was dismissed near the end for dragging down a South African attacker.
Those three send-offs made the match a disciplinary outlier and ensured that all three players will miss the next group fixture. Mexico still finished with a clean sheet and a 2-0 victory, which mattered even more because it was their first win in a World Cup opening match after two draws and five defeats.
A Younger Mexico Also Emerged
Beyond the goals and cards, Mexico’s lineup hinted at a broader transition. Gilberto Mora, only 17, was trusted with a central role in midfield and looked comfortable in a match that demanded quick decisions and maturity. His presence suggested that Mexico is not only chasing points, but also building toward a new core.
South Korea Showed Why It Can Trouble Bigger Names
If Mexico’s match was defined by chaos, the second Group A game in Guadalajara was defined by patience. South Korea and Czechia played in front of a modest crowd at Estadio Akron, but the match quietly turned into one of the most interesting results of the day.
The first half was so flat that both teams were booed off, and Czechia seemed to settle the contest when captain Ladislav Krejčí headed in a long throw in the 59th minute. That kind of goal has been central to Czechia’s identity, and for a stretch it looked like enough.
South Korea responded with the most polished move of the day. Lee Kang-in found Hwang In-beom with a precise pass, and Hwang used a clever feint to freeze two defenders and the goalkeeper before guiding the equalizer into the corner. The buildup lasted 25 passes, a sequence that showed not just skill but control under pressure.
The match still had one more twist. Tomáš Souček briefly thought he had restored Czechia’s lead with a header in the 77th minute, but the offside flag and a review erased the goal. South Korea then punished the mistake almost immediately. Substitute Oh Hyeon-gyu, who later said a fever made him unsure he could even play, finished Hwang’s low cross for the winner in the 80th minute.
Kim Seung-gyu protected the result with a late diving save, and South Korea walked off with a 2-1 victory that felt deserved. The Koreans produced 15 shots to Czechia’s eight and looked like a team with enough balance to disrupt stronger opposition later in the tournament.
There was also another historic note for the captain. Son Heung-min became one of only two South Korean players to appear at four different World Cups, joining coach Hong Myung-bo in that rare category. That kind of continuity matters in a tournament where experience often becomes the difference between surviving and advancing.
What The Results Mean For Group A And Canada
The opening round left Mexico and South Korea tied on three points, with the hosts sitting first only on goal difference. South Africa and Czechia now face immediate pressure, not just because they lost, but because both teams must recover from disciplinary issues and selection uncertainty before the next matches arrive.
- Mexico earned a crucial home start and showed both quality and control.
- South Korea proved it can absorb pressure and still find a winning pattern.
- South Africa must deal with suspensions after a chaotic opener.
- Czechia needs a faster response after wasting key moments.
Canada enters the picture next, and its timing could hardly be more dramatic. The national team opens Friday at a sold-out BMO Field in Toronto against Bosnia and Herzegovina, which will be the first men’s World Cup match ever played on Canadian soil. Jesse Marsch’s side shares Group B with Bosnia, Qatar, and Switzerland, and it will finish its group-stage matches at BC Place in Vancouver.
That means the Canadian team now has a detailed opening-day script to study. Mexico showed how much a host-nation crowd can sharpen every duel, while South Korea demonstrated that a disciplined comeback can flip a match even after a slow start. For Canada, both lessons matter: the first for the atmosphere, the second for the football.
The tournament did not ease into itself. It arrived with a tearful striker, three red cards, a fever-hit substitute winner, and a comeback built on 25 consecutive passes. If that is the tone before Canada even kicks off, the next phase of the event already feels larger, louder, and far less predictable than a standard World Cup opening day.
