Harry Kane has given his first verdict on the much-talked-about altitude at Mexico’s Estadio Azteca.
The famous stadium in Mexico City sits 2,200 metres above sea level. At that altitude, the Earth's barometric pressure is lower, meaning the air is thinner. That means less oxygen is taken into the bloodstream with each breath.
England manager Thomas Tuchel believes dealing with the altitude will be very difficult, calling it a “huge disadvantage” for his players, who arrived in Mexico around 48 hours before kick-off.
All four of Mexico’s previous matches at the tournament have been on home soil and they have been training here too. It means they have acclimatised already and head into the game with an advantage.
Speaking to BBC Sport ahead of the game, England captain Harry Kane played down the adverse effects.
Asked if he has felt the impacts of the altitude, Kane said: "So far so good. Haven't really felt it.
“Slept well both nights and trained well yesterday. The whole team looked sharp.
“We'll have to see as the game progresses whether it has an impact. We just have to deal with it, there's nothing we can do about it.
“It's not an excuse. We back ourselves against a good side and we have to go out there and do that."
