England play Mexico in the World Cup last 16 at Mexico City’s Estadio Azteca, a venue known for high altitude. England’s head coach Thomas Tuchel says Mexico is likely to have a major advantage because players will be operating around 7,000 to 7,200 feet above sea level, which can affect breathing and physical performance. Tuchel also criticises FIFA rules, saying they have limited England’s options for acclimatisation. The Football Association explored approaches to deal with the altitude and research with other sports, including the British Olympic team. It considered a plan that would involve arriving well ahead of the match to adjust to local conditions, but Tuchel says FIFA’s regulations have ruled out that preferred timing. He adds that England have had to adapt their plans within those constraints and has highlighted concerns about player welfare, including an instance involving Declan Rice coming off with what Tuchel described as severe pain. The reports collectively frame the match as one where altitude and England’s preparation window are central issues entering the tie.
