Messi to lead Argentina’s unchanged core at World Cup defence

Argentina’s defence took shape with a familiar centre of gravity: Lionel Messi, 38, was named in the 26-man squad and is set for a sixth World Cup, extending a national record that now spans nearly two decades. But the larger message from Lionel Scaloni’s selection was not nostalgia. By keeping 17 players from the group that won in Qatar in 2022, Argentina signalled that it wants to defend the title with structure, not sentiment.

That continuity matters because the 2026 tournament will be the largest in World Cup history, with 48 teams, 104 matches and three hosts in Canada, Mexico and the United States. Argentina was drawn into Group J alongside Algeria, Austria and Jordan, with the opening match set for June 11 in Mexico City and the final scheduled for July 19 in New York/New Jersey. The scale of the event will demand travel management, rotation and squad depth in a way that rewards teams with established habits.

At the heart of that spine remain Emiliano Martinez, Nicolas Otamendi, Rodrigo De Paul, Alexis Mac Allister, Enzo Fernandez, Julian Alvarez and Lautaro Martinez, all retained from the 2022 championship side. Messi remains the emotional and tactical focal point, but Argentina’s selection suggests Scaloni is trying to spread responsibility across a group that already knows how to win on the biggest stage. The defending champions are trying to become only the third side ever to retain the World Cup and the first men’s team to do so since Brazil in 1962.

The final roster also reflected a changing of the guard. Several names from the Qatar squad did not return, including Franco Armani, Juan Foyth, German Pezzella, Marcos Acuna, Angel Di Maria, Alejandro Gomez, Guido Rodriguez, Paulo Dybala and Angel Correa. The official AFA prelist sent to FIFA on May 10 showed how broad the talent pool had become before the final cut, with younger options such as Franco Mastantuono, Gianluca Prestianni, Valentin Barco, Jose Manuel Lopez and Nico Paz part of the wider conversation.

Fitness will be part of the test from the start. FIFA noted that Messi arrived after some physical discomfort in his last match for Inter Miami, while Emiliano Martinez and Cristian Romero were also carrying injury concerns. Scaloni has made clear that Argentina intends to keep its established style while retaining the ability to adapt if needed. That balance, more than the symbolism of Messi’s sixth World Cup, will decide whether this remains the final act of a legend or the start of a successful succession.
