The baseline metrics: The upcoming World Cup round of 16 match on Monday will take place at the famous Mexico City Stadium, which sits at an impressive 2,240 metres (approximately 7,350 feet) above sea level.
This extreme elevation is vastly different from what Thomas Tuchel's squad experienced in their round of 32 win at the Atlanta Stadium, which sits just 312 metres up.
Atmospheric conditions: At this high altitude, the atmospheric pressure drops significantly, and the air molecules become much more spaced out.
As a consequence, players will intake fewer oxygen molecules with every breath they take during the match.
Accelerated physical exhaustion: Sprinting power and aerobic capacity are known to decline sharply when pushing past the 2,000-metre threshold.
