Messi at 39: Inside His World Cup Birthday, Record-Breaking Run, and Farewell Tour

How Argentina Honored Its Captain

The tributes were not limited to the camp. Across Argentina, network Telefé launched a campaign under the hashtag #CumpleLEO, asking citizens to stop what they were doing at 10 a.m. and 10 p.m. local time to sing "Happy Birthday" to Messi — a nod to his iconic number 10 jersey . Fans held street celebrations, waved flags, and gathered at public squares nationwide . In a more permanent tribute, a 26-meter (85-foot) statue of Messi, made of 70 tons of steel and iron, was erected in a remote Patagonian town, and a mural composed of over 1,300 fan portraits was unveiled during the tournament .

President Javier Milei publicly joined the celebrations, paying tribute to the captain on social media . FIFA President Gianni Infantino also congratulated Messi after his hat-trick against Algeria earlier in the tournament, writing: "Congratulations to the champion Lionel Messi for scoring his 16th goal in a FIFA World Cup and tying Miroslav Klose's record as the tournament's all-time top scorer!"

Records and Performances at Age 39

Messi entered the 2026 World Cup at 38 and turned 39 during the group stage. The tournament stats he had accumulated by his birthday place him in a category entirely his own:

His opening hat-trick against Algeria also saw him break six individual records in a single match, including surpassing Ronaldo (Brazil) for goals and becoming the oldest player to score a hat-trick in the tournament (aged 38 years and 357 days) . He also became the first male player to feature in six different World Cup editions .

Expert Explanations for His Longevity

Multiple experts and former teammates have explained how Messi remains elite at an age when most attackers have long retired:

• Football intelligence (Xavi): "Messi is always scanning his surroundings. Even before receiving the ball, he keeps checking where the opposing defensive midfielder is… On the pitch, he is reading the game three steps ahead." This cognitive edge compensates for any decline in raw physical speed .
• Diet overhaul: Messi cut sugar, soda, and red meat from his diet, shifting to whole foods. The turning point came in 2014 with Italian nutritionist Giuliano Poser; Messi returned three kilograms lighter and consistency in nutrition, sleep, and functional training has extended his career .
• Sport science (Auckland University): As muscle fibers age and reaction time slows, elite experience and anticipatory skill can compensate. Messi's "reading of the game" is cited as the primary offset for biological aging .
• Austria coach Ralf Rangnick: Called Messi "almost not human" and pointed to his inability to accept defeat and his obsessive professionalism as core drivers .
• Disciplined recovery: Experts at health and sport science outlets note rigorous recovery routines, sleep hygiene, and modern sports medicine as key factors .
• Messi's own words: "I don't think about my age on the pitch, but rather the pleasure of playing football. My body will tell me when it's time," he said on his birthday. "God has given me so much, another World Cup would be too much" .

Why This World Cup Is Viewed as a Farewell Tour

The evidence consistently points to the 2026 World Cup being Messi's valedictory campaign:

• Messi himself signaled finality. In pre-tournament comments, he said, "God has given me so much, another World Cup would be too much," and acknowledged his age and fitness would determine his ability to defend the title .
• He will be 43 by 2030. Barring an unprecedented extension, no player has competed at a World Cup at that age at an elite level.
• The emotional tone. Teammates, the federation, and fans are treating every match as a potential last dance. The Argentina team's social media posts, the nationwide birthday coordination, and the farewell-style murals and statues all reflect a collective sense of closing a historic chapter .
• Physical toll. Earlier in 2026, Messi was managing "overload associated with muscle fatigue in his left hamstring" and was not considered fully fit entering the tournament, reinforcing the sense that this is a final push .
• Argentina is defending champion. The narrative of a title defense led by a 39-year-old icon who "completed football" in 2022 but returned for one more run adds to the farewell framing .

As of his birthday, Argentina had already secured its place in the knockout stage, and Messi had scored five goals in just two matches — a rate that, at 39, defies conventional sports science .
