For nearly twenty years, football's biggest question has had only two answers. This summer, Lionel Messi and Cristiano Ronaldo will share a World Cup stage one final time — each appearing in a record sixth tournament.
Messi, 38, arrives as the defending champion, having finally captured the trophy with Argentina in Qatar in 2022. He turns 39 between Argentina's first two group games, and every touch in North America could be the last World Cup touch of the greatest career of his era.
Ronaldo, 41, remains men's international football's all-time leading scorer, and the World Cup is the one great prize that has escaped him. Portugal's deep, talented squad gives the ultimate competitor one last, improbable shot.
Whatever happens, the 2026 World Cup is the end of an argument that defined a generation — and the start of the next one, with Lamine Yamal, Jude Bellingham and Erling Haaland ready to inherit the stage.
