Nagelsmann’s Jetlag Struggle: How Chicago’s Extreme Climate Control Is Testing Germany’s World Cup Coach
Bundestrainer Julian Nagelsmann arrived in Chicago with one mission: prepare Germany’s World Cup squad without delay. But the 37-year-old coach’s first 24 hours in the United States have been complicated by the extreme climate control inside his team’s hotel and training facilities—a battle he described with characteristic bluntness. Meanwhile, Portugal’s 3-2 test win over Chile in another World Cup warm-up match was marred by an on-field incident that has sparked debate among fans and pundits.
Nagelsmann’s “Arschkalt” Moment: The Climate Control Crisis
In an interview with German media after his team’s first training session in Chicago, Nagelsmann revealed the unexpected challenge of America’s indoor climate systems. “Arschkalt im Flieger,” he said with a raspy voice, referring to the frigid temperatures inside the aircraft and hotel rooms—an experience that has left him battling both jetlag and the aftereffects of what he described as “extreme conditioning” from the air conditioning.
Nagelsmann’s team has been training at the Chicago Fire’s facilities, where the indoor temperatures are tightly regulated to maintain optimal playing conditions. However, the contrast between the controlled indoor environment and the humid Chicago summer outside has tested the squad’s adaptation. “The body needs time to adjust,” Nagelsmann noted, adding that while the players are physically prepared, the mental shift to the time zone and climate remains a work in progress.
Key detail: Nagelsmann’s first training session in Chicago took place behind closed doors at 13:00 CDT (18:00 UTC) on June 6, with only the core squad present. The session focused on tactical adjustments ahead of Germany’s June 10 friendly against the United States.
Portugal’s Test Win Overshadowed by Controversy
While Germany’s preparations face logistical hurdles, Portugal secured a 3-2 victory over Chile in their own World Cup warm-up match. The result was overshadowed by an incident involving an alleged foul by Portugal’s Cristiano Ronaldo during the second half. Chilean defender Gabriel Aravena was treated for a suspected concussion after a collision with Ronaldo, leading to a brief stoppage and medical assessment.
The incident has reignited debates about fair play in high-stakes friendlies, with Chilean fans and pundits criticizing what they described as “reckless challenges” from Portugal’s forwards. The Portuguese Football Federation has not yet issued an official statement, but sources close to the team suggest Ronaldo was “disappointed” by the incident, which occurred in the 68th minute.

What This Means for Germany’s World Cup Campaign
Nagelsmann’s ability to manage these early challenges will set the tone for Germany’s World Cup preparations. The coach has emphasized that his squad’s mental resilience will be tested as much by logistical hurdles as by on-field competition. “We’re not just preparing for matches—we’re preparing for the entire tournament environment,” he stated.
Three immediate implications:
- Injury risk: The rapid transition between time zones and extreme indoor climates could increase the risk of minor injuries or fatigue-related setbacks. Nagelsmann has already highlighted Manuel Neuer’s ongoing recovery from a calf strain as a critical area to monitor.
- Tactical adjustments: The closed-door training sessions in Chicago are designed to refine Germany’s system against the USA, a team known for its aggressive pressing and direct play. Nagelsmann has hinted at potential changes to Germany’s defensive structure to counter this.
- Player morale: While the squad remains professional, the cumulative stress of travel, climate adaptation, and high-stakes preparation could test team cohesion. Nagelsmann’s leadership in managing these factors will be closely watched.
Context: This is Nagelsmann’s first World Cup as Germany’s head coach. His ability to navigate these early challenges will be scrutinized as a potential indicator of how he handles pressure in the tournament proper, which begins on June 14 in Toronto.
