Lionel Messi opened Argentina’s 2026 World Cup title defense with a stunning hat trick in a 3-0 win over Algeria, in his 200th appearance for the national team. The performance came just two days before his 39th birthday and prompted emotional reactions on the touchline from coach Lionel Scaloni, while stars such as Erling Haaland posted astonished selfies online saying, in effect, that Messi was unbelievable.
A detailed Athletic report says the secret is not magic alone, but a combination of science, technology, artificial intelligence and relentless competitive drive. The story begins with Inter Miami coach Guillermo Hoyos, who introduced a brutal internal tournament called the “Super League” in spring, with small-sided teams, daily standings and scoring charts on a locker-room whiteboard. Messi reportedly scored more than 80 goals there, while no other Miami player surpassed 30.
The article also describes strict daily maintenance for Messi’s body. He has completely changed his diet, dropping chocolate and soft drinks in favor of fish, premium meat and salads. Inter Miami upgraded its Fort Lauderdale training facilities for him and assigned Walter Insaurralde, Argentina’s official physiotherapist, to him on a regular basis. He also trains twice a week with close friend Rodrigo De Paul, adding resistance work and sprints that have helped restore his explosiveness.
Argentina has taken the approach further by using AI to track Messi’s entire sporting history, including minutes played, previous injuries and exact nutrition habits. Leandro Petersen, the federation’s marketing vice president, said, “We can track the entire history of the athlete through advanced systems.” That data was crucial after Messi arrived at camp with a troubling hamstring issue and did not train for a week, because it allowed the medical staff to design a personalized recovery and injury-prevention plan that led to his standout match against Algeria. The piece notes that critics once assumed the 2018 World Cup was his last, but Messi went on to win in Qatar, move to the United States and now play his sixth World Cup, tied with Cristiano Ronaldo for a historic record. With 2030 set to open in Buenos Aires before games in Spain, Portugal and Morocco, the article suggests it would be risky to bet this is truly his final tournament.
