Portugal's golden generation still leans on 40-year-old Ronaldo, and the 9% odds reflect a squad that's never reached a World Cup final.
Portugal officially named its 26-player roster for the 2026 FIFA World Cup on Tuesday, May 19, 2026, with Cristiano Ronaldo, age 41, headlining the squad in what is widely expected to be his final tournament appearance. The selection marks Ronaldo's sixth World Cup roster, a record-tying milestone, as the Al Nassr forward seeks the one major trophy that has eluded him across a career that includes three Premier League titles and the 2008 Champions League. Portugal has never lifted the World Cup, with Ronaldo's best finish a semifinal exit in 2006. [FOX Sports, May 19]
The portugal fifa world cup campaign opens with two group-stage matches in Houston, where the federation has based its opening fixtures. Midfielder Vitinha publicly framed the tournament as a collective bid to win "with him and for him," referencing Ronaldo's standing within the dressing room. The squad blends veteran leadership with the Paris Saint-Germain and Manchester City core that has elevated Portugal's standing in recent UEFA competition, though the team enters the field at 9% implied odds to win the trophy outright. Historical precedent weighs against the campaign: only eight nations have ever won the World Cup, and no European side has won the tournament when hosted in the Americas. [Sporting News, May 18]
The tournament will be co-hosted by the United States, Canada, and Mexico, with the expanded 48-team format debuting for the first time. Portugal's path will require navigating a group stage followed by a Round of 32, adding a knockout round compared to previous editions and lengthening the route to the final. Ronaldo's record at the World Cup remains the standing question: despite nine career tournament goals, he has never advanced past the semifinals, and Portugal has not reached a World Cup final in its history. The portugal fifa world cup roster announcement closes the federation's selection window ahead of pre-tournament friendlies. [Houston Chronicle, May 19]
