The night before the World Championships: what goes on in an athlete's mind?

Tomorrow, June 11, 2026, the biggest World Cup in football history opens. Forty-eight national teams, three host countries, billions of people watching. And hundreds of athletes who won't sleep tonight. What goes on in a player's mind the night before the most important match of his career? Science answers.

There's a moment in sports that doesn't appear in the statistics, doesn't end up in the highlights, and is never interviewed. It's the night before. The night when a player is alone with himself and what he's about to face. It's the night when butterflies in the stomach flutter in every direction, when the mind tends to jump ahead—to the game, to the opponents, to the mistakes you don't want to make, to the goals you want to achieve—before the referee has even blown the starting whistle.

Tomorrow, June 11, 2026, at 9:00 PM Italian time, Mexico takes the field against South Africa at the Estadio Azteca in Mexico City, kicking off the largest World Cup in football history: forty-eight national teams, sixteen host cities, and three co-hosts. For many of the athletes on the pitch, it's their first time on that stage. For some, it's their last. For others—like Lionel Messi, 38, with seventeen 2022 World Cup winners in his wake—it's the impossible challenge of defending what's already been won.

This article isn't about tactics or predictions. It's about what's going on in the minds of those athletes tonight. And what sports psychology has learned, through decades of research, about the most difficult—and most valuable—night of a sports career.

01 - THE CONTEXT

The biggest World Cup ever

The 2026 World Cup is a first in football history. For the first time, 48 national teams will compete instead of the usual 32, with a group stage that expands to include the eight best third-place teams. The matches will be held across Mexico, Canada, and the United States, at sixteen different venues. This is the first edition in which FIFA has introduced a new pre-match ceremony: the players of the two teams stand face-to-face at the center of the pitch during the national anthems, in what FIFA President Gianni Infantino called "a moment of unity, pride, and emotion that belongs to all the team members and everyone in the stadium."

On a human level, the tournament's greatness is measured by the stories that permeate it. Yuto Nagatomo, a 39-year-old Japanese defender, cried when he heard his name called up: it's his fifth World Cup. AC Milan forward Santiago Gimenez describes the tournament as "an incredible dream" and says he can't wait for it to begin. On the other hand, Carlo Ancelotti—the first foreign coach in Brazil's history—bears the weight of a country that hasn't won the World Cup since 2002 and has placed enormous expectations on him. His response on the eve of the tournament is as succinct as it is revealing: "The team that can hide its weaknesses will win the World Cup."

02 - THE SCIENCE

What happens in the mind the night before

Call it what you will: pre-competitive anxiety, activation, agitation. The feeling is universal: a racing heartbeat, muscle tension, racing thoughts, difficulty falling asleep. For decades, sports psychology has treated these symptoms as something to be eliminated—or at least reduced. More recent research tells a more complex and, in a certain sense, more reassuring story.

The Individual Zone of Optimal Functioning (IZOF) model, developed by Yuri Hanin, has shown that optimal emotional arousal is different for every athlete: there is no "right" level of agitation that works for everyone. For some, very high arousal is functional; for others, a state of almost detached calm produces the best performance. What matters is not the quantity of emotion, but its relationship to that individual athlete's optimal zone at that moment. A player who learns to know their zone—and recognizes when they are in or out of it—has a real competitive advantage over those who have never explored it.

But the most revolutionary contribution to understanding the night before comes from research on British Olympic swimmers. Hanton and Jones, in a study that has become a classic in the literature on sport psychology, showed that elite athletes don't try to eliminate pre-competitive anxiety: they reinterpret it. Faced with the same physical symptoms—racing heartbeat, butterflies in the stomach, sweaty palms—non-elite athletes read them as danger signals ("I'm too nervous, I won't do it"), while elite athletes read them as signals of readiness ("My body is preparing, I'm ready"). The same physiological state, two radically different narratives, two radically different performance outcomes. The title of the study has become a famous phrase in applied psychology: Making the butterflies fly in formation.

The underlying mechanism can be explained through Blascovich and Tomaka's Challenge vs. Threat model: when faced with a high-stakes situation (a decisive penalty in a Champions League final), the body can respond in two ways. If perceived resources are sufficient to address the demand—"I'm ready, I've already been through this, I know what to do"—a challenge response is activated, with increased cardiovascular output and cognitive focus on the task. If, however, the demand exceeds perceived resources, a threat response is activated, with vasoconstriction, attentional dispersion, and increased risk of error. Accumulated experience shifts the balance point: an athlete who has already taken decisive penalties perceives his resources as more adequate to the situation.

03 - THE PROTAGONISTS

Three stories, three vigils

The eve of the 2026 World Cup offers three very different psychological portraits—three ways of approaching the night before that, each in their own way, reveal something specific about the psychology of high-level performance.

Three stories that illustrate as many psychological profiles facing the night before. Messi carries the heaviest weight of identity: he is the symbol, he is the target of every opponent, he is the one asked to do the impossible. Research on mental toughness—conducted by Jones, Hanton, and Connaughton through interviews with Olympic athletes and top coaches—describes this ability as the determination to not be overwhelmed by what is expected of you, maintaining focus and confidence even under maximum external pressure.

Nagatomo represents the opposite: an athlete who has transformed decades of career into a positive emotional resource. For him, the eve of the tournament isn't a threat—it's memory. Every match of this World Cup will be viewed through the filter of all previous matches, and this filter lowers the perception of risk and increases the sense of mastery. Experience, in sports psychology, isn't just technique: it's an archive of events the brain uses to assess its readiness.

Finally, Ancelotti paints the portrait of a leader who has learned to manage his eve through decades of maximum pressure. His phrase—"hiding your weaknesses"—isn't cynical: it's a working definition of what sports psychology calls task orientation under stress. Don't think about how much you can lose, but what you can actually do to win.

04 - THE RESEARCH

What distinguishes those who hold the night before

The most important question in pre-competitive psychology is not "how to eliminate anxiety," but "what distinguishes athletes who manage it well from those who don't." Research has identified fairly precise answers.

Orlick and Partington's study of 235 Canadian Olympic athletes—participating in the 1984 Sarajevo and Los Angeles Games—produced one of the most comprehensive data sets on pre-competition mental preparation in the history of sport psychology. The key finding: athletes who perform at their optimal level under maximum pressure share recurring elements in their pre-competition management. It's not talent that makes the difference in major events, but the quality of pre-competition mental preparation. Among the factors identified as critical: the use of consolidated pre-competition routines, the ability to focus attention on the technical task rather than the consequences of the outcome, and the presence of a support system—coach, staff, teammates—that is perceived as solid.

This finding translates directly into practice: you don't build the night before. It's built in the months leading up to the World Championships, through the repetition of routines that become automatic, through mental simulation of adverse scenarios, through working on the athlete's narrative about themselves and the situation they're about to face. Those who arrive at the World Championships with a well-oiled mental system sleep better, not because they don't feel the pressure, but because they've already practiced how to respond to it.

05 — THE COLLECTIVE DIMENSION

The night of an entire country

The eve of the World Cup isn't just individual psychology. It's collective psychology. Hundreds of millions of people around the world—fans, families, entire countries—share the same tension, the same anticipation, the same sense of something about to happen that will change the collective mood for a month. In Italy, this feeling is amplified by absence: for the third consecutive edition, the Azzurri are not on the pitch, and the World Cup will be experienced from the sidelines—with that bittersweet feeling of watching a party they weren't invited to.

Yet there's something universal about the eve that transcends flags and jerseys. The night before the big event is one of the most shared emotional states in the sporting experience: the anticipation, the excitement, the inability to fall asleep, the imagining of how it will go. It's the moment when sport—in its deepest sense—stops being a game and becomes something bigger. Something that touches on identity, personal history, the sense of belonging.

For the athletes on the pitch tomorrow, this dimension is experienced with multiplied intensity. They're not just playing a match: they're representing their country, their history, the expectations of millions of people. This is the most difficult pressure to handle—not the pressure that comes from the opponent, but the pressure that comes from within, from the weight of everything that comes with wearing a World Cup jersey.

06 — CLOSING

The night as part of the game

There's a quote from the repertoire of sports psychology worth keeping in mind tonight, for anyone reading it—athlete, coach, parent, or fan. Butterflies in your stomach aren't the problem. They're a sign that you care. They're proof that what you're about to do matters. The job isn't to eliminate them: it's to learn to let them fly together, in the same direction.

Tomorrow morning, in hotels across Mexico, Canada, and the United States, hundreds of athletes will wake up—some for better, some for worse—with that feeling in their chests. The most prepared won't try to make it go away. They'll recognize it as part of the game, they'll integrate it into their routine, they'll direct it toward the task. And then they'll take to the field.

This is the psychology of the eve of a match. Not the certainty of victory, not the absence of fear: the ability to use what you feel to do what you have to do. Good luck to everyone.
