Argentina's World Cup this time: from "Legs Running to Break" to "Precise Nuclear Bomb"

In the 2022 Qatar World Cup, Messi was basically a maniac—ran 12.1 kilometers throughout the match, rescuing fires everywhere, dropping back to receive the ball, organizing attacks, and even scoring himself in the final moments.
That tournament, he was the team's engine + finisher + spiritual pillar. Still fighting so hard at 35—it's simply a miracle.
Four years later, at the 2026 USA-Canada-Mexico World Cup, 38-year-old Messi's role has completely changed. Scaloni's tactics now revolve around him, but only let him do the most precise, deadliest things.
No longer needing him to run around the field saving fires, but instead like a nuclear warhead, placed in the most suitable position, ready to explode with a light touch.
Overall lineup framework (main lineup expected to be a 4-3-3 or 4-2-3-1 variation)
Goalkeeper: Emiliano Martínez (Dibu is still that Dibu, the shot-stopper)
Defenders: Molina / Romero + Lisandro Martínez / Otamendi / Tagliafico (defensive line is rock-solid, full of experience)
Midfield: Enzo Fernández + McAllister + De Paul (young + energetic + tough, a tireless midfield trio)
Forwards: Messi (free role/right wing/false nine) + Lautaro Martínez / Julián Álvarez (assault rifle) + Almada / Nicolás Paredes (young technical flow)
17 members from the Qatar champion squad remain, with immense experience, but fresh blood (Almada, Paredes, etc.) bring more vitality.
Messi's role has greatly upgraded:
Previously:
Messi was an "all-round warrior," dropping back to midfield to receive the ball, breaking through on the wings, making runs into the box, and helping defend... huge physical consumption.
Now: The team builds a "small collective system" around him— a group of diligent, technically skilled young players (Álvarez, Almada, De Paul, etc.) run wildly, pull space, set screens, track back to press, doing all the dirty work.
Messi only needs:
1. To receive the ball in the most comfortable position
2. One deadly through pass
3. Precise shooting
4. Threatening set pieces
5. Deciding matches with brains and magic on his feet
His activity range is more自由, but running distance has significantly decreased, focusing more on "precise strikes."
Scaloni clearly said: how to use Messi in each game will be discussed with him, to protect his body and let him play happily and effectively.
In the first match against Algeria, Messi scored a hat-trick, easily leading the team to a 3-0 victory, and even requested to be substituted to rest.
This is the benefit of the new role: he remains invincible at critical moments, but doesn't have to run himself to exhaustion every game.
Why change like this? Very smart.
38-year-old Messi's speed and stamina are definitely declining, but his football IQ and finishing ability are still at their peak.
Rather than letting him continue to do the hard work, it's better to let him make "decisive moves." His teammates are also more mature now, no longer the team four years ago that "relied entirely on Messi to carry." Now it's Messi + a pack of wolves.
This Argentina team not only retains the champion's foundation but also makes the most comfortable tactical adjustments based on Messi's age. The road to defending the title is tough, but it looks... like they are very well prepared.
Messi's final dance is no longer about running until exhaustion, but about brains and magic. Looking forward to him continuing to shine!
