Why will playing 7,350 feet above sea level at Azteca Stadium be tough for England?

England will face Mexico in their FIFA World Cup 2026 Round-of-16 clash at Azteca Stadium, which stands 7,350 feet above sea level. According to experts, thinner air reduces oxygen intake, slows sprint recovery and can cut high-velocity running by up to 21%, while also making the ball travel faster. Notably, Mexico have lost just twice in 89 matches there.
