Leading sports scientists have uncovered the key factor that could help the Three Lions overcome Mexico in their World Cup round of 16 clash.

England face Mexico at the legendary Estadio Azteca in Mexico City — a venue steeped in football history. It will be England’s first game there since Diego Maradona’s Argentina famously eliminated them in the quarter-finals of the 1986 World Cup, courtesy of the infamous Hand of God goal.

The Azteca, however, presents a unique test. Sitting 7,220 feet (2,200 metres) above sea level, it exposes players to thinner air and reduced oxygen levels. For Thomas Tuchel’s men, that makes their attempt to reach the quarter-finals even tougher — especially against a Mexico side that has yet to concede a goal in four matches at this tournament.

The Estadio Azteca’s altitude means lower barometric pressure, resulting in less oxygen entering the bloodstream with each breath. The effects can be severe — quicker fatigue, dehydration, higher heart rates, and slower recovery between sprints. Sprinting speed itself may not drop, but recovery time between efforts will increase noticeably.

Tuchel has admitted that playing at high altitude poses a “huge disadvantage.” While Mexico have played all their matches on home soil and trained at altitude, England have not had that luxury.

Dominic Rae, Head of Sports Medicine and Performance at The Ten Percent Club, explains: “The Mexican players have been living in these conditions for weeks now. They’ve adapted and understand how to manage their energy and hydration better during matches. That’s a big advantage.”

Rae adds that while the altitude is not extreme compared to locations used in adventure or endurance sports, Mexico’s record at the Azteca speaks volumes. They have lost only two of 89 matches played there — a statistic that underscores how tough the venue is for visiting teams.

“By the end of the match, players expected to go the full 90 minutes will likely experience a significant drop in output,” Rae says.

Ideally, England would have arrived and played immediately to avoid the full impact of altitude, which becomes more pronounced after 24 hours. However, FIFA’s rulebook requires teams from the round of 16 onwards to train in the host city the day before their fixture. Consequently, England had to travel to Mexico on Friday night following training at their Kansas City base — a situation that has left Tuchel and his staff frustrated.

Midfielder Elliot Anderson took proactive steps before the tournament, installing a hyperbaric chamber at home to simulate altitude conditions. Rae notes that, in theory, such measures could increase red blood cell production. “I’ve heard that some of the squad have also used altitude tents,” he adds, “but I’m not convinced they’ve had enough time to gain real benefit. True acclimatisation takes one to four weeks.”

England did conduct a warm-weather training camp in Barcelona last summer and spent 11 days in Miami before the World Cup, focusing on heat and humidity. While not a direct substitute for altitude training, such preparation can still provide physiological benefits.

“When you’re in thinner air, your body has to work harder to regulate itself,” Rae explains. “Training in heat helps you control your sweating rate — a skill that can indirectly help at altitude, where staying hydrated and managing body temperature are vital.”

Strategically, England will aim to start strong but conserve energy. Rae suggests: “If they score first, they can sit a bit deeper and manage the tempo better. Mexico love fast starts, so England will need multiple tactical options — plans A, B, and C — ready to go.”

He also stresses the importance of a proper warm-up inside the stadium before kick-off. “Even a short time spent running and breathing in that air before the match helps your body begin adjusting,” Rae says. “Substitutes, on the other hand, might find it especially tough — sitting on the bench and then suddenly entering a match at altitude feels completely different.”

Ultimately, England’s ability to adapt quickly, manage their energy, and employ smart tactics will determine whether they can overcome Mexico’s home advantage at the Azteca and book their place in the World Cup quarter-finals.
