Manchester City and New York Cosmos legend Dennis Tueart has issued a stark warning to the England national team regarding the potentially extreme heat and humidity they may face when playing in the United States. Tueart, who played for the New York Cosmos in the late 1970s, shared his experiences of adapting to American playing conditions, particularly the oppressive humidity that significantly impacted performance.

Tueart's firsthand account highlights the physical toll that playing in high temperatures can take. During his first game for the New York Cosmos in 1978, he experienced an overwhelming humidity that left him unable to breathe properly when attempting to attack after tracking back. "The humidity just hit me, unbelievable. This is what playing in America during a mid-afternoon kick-off does to you," Tueart stated. He noted that he received no acclimatization upon arrival and quickly realized the challenge posed by the climate.

He recalled that during halftime in matches, players would place their feet in dishes of cold water to cool down. Tueart also described playing on Astroturf, which he found problematic. In one instance, a slide to block a cross resulted in the skin being ripped from his thigh. He noted that the current World Cup matches, scheduled to be played in MetLife Stadium – a venue built on the site of the former Giants Stadium where Tueart played – are benefiting from hydration breaks, a practice that was not available in his era. "We used to have dishes of cold water in the locker room at half time so you could put your feet in them. Just to cool ourselves down," Tueart said.

Tueart anticipates the MetLife Stadium pitch could become extremely hot, comparing it to a "boiling point" due to the enclosed nature of large stadiums. "The humidity is killing. It really is. It’s a good job they have the drinks breaks when the conditions are like that. We didn’t have those," he added. While England might encounter milder temperatures for their match against Panama, Tueart pointed out that the forecast for the latter stages of the tournament suggests temperatures could reach as high as 37 degrees Celsius (98.6 degrees Fahrenheit).

Reflecting on the strategic aspects of the game during his time, Tueart mentioned a rule where offside was only called if a player was beyond the 35-yard line. This, he explained, allowed defenses to push up less aggressively, giving midfielders like Franz Beckenbauer more time on the ball. He also praised his former Cosmos teammates, including Vladislav Bogicevic, for their accuracy and precision in passing, a crucial element for conserving energy in hot weather. "That is key in the searingly hot American weather. Don’t waste anything," Tueart emphasized. He advised that a key strategy for any team facing these conditions is to be efficient with every action on the field to manage physical exertion.
