Mexico Going Into This Match — What You Need to Know
Mexico had an almost perfect opening match. They beat South Africa 2-0 at the Azteca Stadium in Mexico City in front of a screaming crowd that made the ground shake.
Julián Quiñones scored in just the 9th minute — the very first goal of the entire 2026 World Cup. Raúl Jiménez then sealed it with a header in the 67th minute.
Here is what is different about this Mexico team tonight:
• They are playing at home in Guadalajara, on Mexican soil, with 48,000 home fans
• César Montes is suspended — he got a red card vs South Africa and cannot play
• Jiménez is in form — four goals in Mexico's last five matches before this tournament
• Mexico have beaten South Korea in both previous World Cup meetings — 3-1 in 1998 and 2-1 in 2018
Mexico have never lost a World Cup group stage match at home. Never. In their entire history. Tonight they play at home again.
South Korea Going Into This Match — What You Need to Know
South Korea's win over Czechia was the type of performance that makes football fans fall in love with this team.
They were losing 1-0 going into the final 20 minutes. Most teams would have accepted the point and moved on. South Korea did not.
Hwang In-beom equalised. Then he set up Oh Hyeon-gyu for the winner in the 80th minute. A comeback from behind at a World Cup. That takes character.
But the player every fan on Ultimate Rankings keeps mentioning is Son Heung-min.
Son did not score against Czechia. But he stretched the defence, created space, and drew fouls in dangerous positions. And here is the scary part for Mexico fans.
What South Korea bring to tonight's match:
• Son Heung-min — 34 years old, playing his last World Cup, with something massive to prove
• Lee Kang-in — most creative South Korean player, exceptional at finding space
• The best counter-attacking system in the group — they do not need the ball to hurt you
• A comeback mentality — they came from behind against Czechia. They can do it again.
The Key Battles That Will Decide This Match
When you strip everything away, three individual battles will decide tonight's game.
Battle 1 — Raúl Jiménez vs Kim Min-jae
Mexico's striker against South Korea's best defender. Kim Min-jae plays for Bayern Munich and is one of the best centre-backs in the world right now. Can Jiménez beat him the way he beat South Africa's defence? If he can, Mexico will win.
Battle 2 — Son Heung-min vs Israel Reyes
Son will attack Mexico's right repeatedly. Reyes has never faced anyone at Son's level in a game this big. This could be the moment that decides the entire match. If Son gets past Reyes even once cleanly, a goal is coming.
Battle 3 — Who Scores First
History shows the team that scores first in this fixture almost always wins. Mexico scored first against South Africa. South Korea came from behind against Czechia. Tonight, the first goal is everything.
What Fans on Ultimate Rankings Are Saying
We put a simple question to fans at Ultimate Rankings before tonight's match: Who wins?

The Group A World Cup 2026 battle is far from decided.
This Debate Will Be Settled On The Pitch Tonight
Football is the greatest sport in the world for one reason.
Nobody knows what is going to happen.
Mexico are co-hosts. They have home advantage. They beat their first opponent comfortably. On paper, they should win.
But South Korea World Cup 2026 has Son Heung-min playing his last World Cup, with something to prove. They have the best comeback mentality in the group. And they have never been easily beaten.
Mexico vs South Korea World Cup 2026 is the match of the group stage so far. Tonight we find out who takes control of Group A.
