Mexico head coach Javier Aguirre has brushed aside talk of Estadio Azteca's high altitude giving his side a decisive edge when they face England in the FIFA World Cup 2026 round of 16.

Speaking ahead of the match, Aguirre insisted the conditions would not determine the outcome. "It's 11 against 11," he said, adding that Mexico must produce a near-perfect performance to overcome what he described as a "powerful" England side.

The Estadio Azteca sits at 2,240 meters — roughly 7,350 feet — above sea level in Mexico City, where thinner air reduces oxygen intake and causes the ball to move faster than at lower altitudes. The conditions have drawn attention from England head coach Thomas Tuchel, who flagged the environmental challenge facing his squad, particularly given the limited time England have to acclimatize before kick-off.

Aguirre backs his squad, not the conditions

Despite the obvious home advantages — the altitude, the atmosphere, and a passionate Azteca crowd — Aguirre made clear that tactical discipline, not environmental factors, will drive Mexico's push for a quarterfinal place.

"They have major players who play both inside and outside the country," Aguirre said of England. "They're pretty powerful, physically speaking, and they're great players."

He was equally direct about where his attention lies: "I really do not focus on that. It's 11 against 11. The referee is there to point things out. We're 11 Mexican players that need to score in their net, and they're going to try to score in ours."

Aguirre acknowledged the excitement surrounding the squad but said his role is to keep his players grounded. "The group knows — every single one of my players has a smartphone and they're on fire, so they're pretty much aware of the euphoria and optimism out there," he said. "My obligation is that whenever they get too self-confident or ecstatic, I try to ground them."

The coach left no doubt about his belief in Mexico's chances: "If I didn't believe that we could indeed beat England, I would tell you, as a matter of fact. But I firmly believe in how we play. I believe that we are at par, and the team that makes fewer mistakes is going to win."
