The FIFA World Cup 2026 opens in the most storied stadium in football history. Estadio Azteca in Mexico City will host Mexico against South Africa in Match 1 of Group A, setting the tournament in motion at one of the sport’s most iconic venues.

Mexico and South Africa have not met often at World Cups. Their most notable shared tournament history is the 2010 edition in South Africa, where both teams participated in the same competition on home soil for Bafana Bafana. South Africa made history as the first host nation not to advance beyond the group stage, while Mexico reached the Round of 16. The two nations have not crossed paths in the knockout rounds.

For Mexico, the Azteca is sacred ground. It was here in 1970 that Brazil lifted the Jules Rimet Trophy for the third time. It was here in 1986 that Maradona scored both the Hand of God and the Goal of the Century against England in the same quarter-final. For the Mexican national team, playing at home in front of 87,000 passionate fans at altitude is one of the most formidable home advantages in world football.

South Africa’s World Cup history is limited but meaningful. Hosting 2010 was a watershed moment for African football and for the country itself. Bafana Bafana last qualified for a World Cup in 2002, making 2026 a long-awaited return to the global stage.

Group A is tightly contested. Mexico enters as clear favorites given home advantage and decades of World Cup experience, including seven consecutive Round of 16 appearances from 1994 to 2018. A win in Match 1 puts immediate pressure on the rest of the group. For South Africa, opening points against a host nation would be a statement result and a sign that Bafana Bafana are ready to compete at this level again.

Mexico City sits at 2,250 meters above sea level. For players not acclimated to altitude, the thin air becomes a factor late in games. That edge belongs entirely to Mexico.
