Enzo Maresca Battles the Heat as Chelsea’s Club World Cup Preparations Are Disrupted
Sweltering 41°C Temperatures Force Blues to Cut Training Short Ahead of Crucial ES Tunis Clash
As Chelsea prepare to take on Esperance Sportive de Tunis (ES Tunis) in the FIFA Club World Cup, the focus should have been solely on tactics, recovery and match sharpness. Instead, the unforgiving North American summer has thrown Enzo Maresca’s plans into disarray.
With temperatures soaring to 41°C (106°F) in Philadelphia, where Chelsea are based ahead of their next Club World Cup clash, the intense heatwave has not only made full training sessions nearly impossible—it’s also left Maresca visibly frustrated as the clock ticks down toward a must-win match.
What Happened in Philadelphia?
Club World Cup Prep Brought to a Halt by Dangerous Heatwave
The Lincoln Financial Field, home to the NFL’s Philadelphia Eagles, will host Chelsea’s pivotal group-stage fixture. But just across the river at Subaru Park—the training base of MLS side Philadelphia Union—the Blues have struggled to even complete a full session.
In what was meant to be a crucial day of tactical preparation, Chelsea’s coaching staff were forced to cut training short after only a brief run-through. With humidity adding to the stifling heat, staff brought out fans, water sprays, and hydration tents, but it made little difference. Player safety took precedence, and Maresca’s session was dramatically shortened.
Afterwards, the Italian coach didn’t hide his frustration, admitting:
“It is almost impossible to train or to make a session because of the weather. Now we are just trying to save energy for the game. This morning’s session was very, very short. Just planning for tomorrow, and that’s it.”
The Bigger Picture: A Club World Cup Challenge Beyond Football
Heat, Fatigue, and Fixture Pile-Up Are Taking Their Toll
The brutal heat is just the latest challenge in what has been a gruelling 2024–25 season for Chelsea. Maresca pointed out that tomorrow’s clash with ES Tunis will be Chelsea’s 60th game of the season. Some of the players, especially those who featured in international competitions, have surpassed that tally.
The physical and mental toll is beginning to show, and Maresca has clearly prioritised recovery over intensity in recent days. The team is running on fumes, and the oppressive heat in Philadelphia is only making things harder.
“We try to give them as much time as possible for recovery,” said Maresca. “We’ll have cooling breaks during the game, which helps a little. But it’s about managing energy right now.”
Chelsea’s Situation in the Group: Must-Win Scenario
After Flamengo Defeat, There’s No Margin for Error
Having already lost to Flamengo, Chelsea find themselves in a precarious position in the Club World Cup group stage. Nothing less than a victory against ES Tunis will do if they want to progress to the last-16 and keep their hopes of lifting this rare piece of silverware alive.
A second consecutive defeat would not only be damaging to morale—it would effectively knock them out of a competition that offers global prestige and a chance to represent European football at the very top.
It’s also a big moment for Maresca. Still relatively fresh into his reign, the Italian tactician is desperate to make his mark. A positive run at the Club World Cup could give him valuable momentum heading into the new Premier League season. But with Mother Nature disrupting training and his squad running on empty, it’s a major test of his adaptability.
Inside Chelsea’s Weather-Adjusted Preparations

Heat Management Now a Tactical Concern
Chelsea’s backroom team have had to shift their training focus entirely. Where once they might have held double sessions, tactical walkthroughs, and set-piece rehearsals, they’re now relying on video analysis, brief tactical drills, and matchday simulations indoors.
Cooling techniques have been stepped up as well. Ice baths, electrolyte treatments, and light gym-based recovery routines are replacing pitch time. Maresca is effectively walking a tightrope—trying to prepare his team for battle without pushing them over the edge physically.
The medical staff are on high alert. Cramp, dehydration, and fatigue are real threats—not just to performance, but to player health.
A Test of Mental Strength as Well as Physical
Chelsea’s Leadership Group Must Step Up
In such extreme circumstances, leadership becomes just as important as tactics. Senior players like Reece James, Raheem Sterling, and Conor Gallagher are expected to rally the dressing room. Younger talents such as Cole Palmer and Noni Madueke, meanwhile, must quickly adapt to the pressure of knockout football in unfamiliar climates.
The Club World Cup may not carry the same weight as the Champions League or Premier League, but it represents something bigger for a Chelsea side trying to reclaim its identity on the world stage.
A win against Esperance would not only push them through to the next round—it would be a statement that even in the face of extreme adversity, the Blues can rise to the occasion.
What Next for Chelsea and Maresca?
All Eyes on Philadelphia Showdown with Esperance
Kick-off at Lincoln Financial Field will take place in conditions that feel like 40°C. Maresca has confirmed that cooling breaks will be used, but there’s little else he can do besides hope that his side’s quality will shine through, even if their preparation has been far from ideal.
This is now a question of survival and adaptation. And for Chelsea’s manager and players, it’s a moment of truth.
Win, and the dream of Club World Cup glory continues. Lose, and questions will be asked—not just about Maresca’s tactics, but whether Chelsea have the resilience to navigate a chaotic, congested season under pressure.
For now, though, the focus is simple: beat ES Tunis, stay alive, and sweat it out—literally—in pursuit of silverware.
