Cristiano Ronaldo could extend his international career until the 2030 FIFA World Cup, while long-time rival Lionel Messi is widely expected to bring his World Cup journey to an end after the 2026 edition.

The Portuguese star has repeatedly stated that he is not setting a fixed retirement date and remains focused on maintaining his fitness levels despite approaching his mid-40s. If Ronaldo features at the 2030 World Cup, he would be 45 years old, making him one of the oldest players ever to appear in football's biggest tournament.

The possibility has reignited discussions among football fans about the contrasting paths of the two players who have dominated the sport for nearly two decades.

Messi, meanwhile, has yet to officially confirm his international retirement plans. However, the Argentine icon is expected by many observers to make the 2026 World Cup his final appearance on the global stage.

The eight-time Ballon d'Or winner achieved the one major accomplishment missing from his career when he led Argentina to World Cup glory in Qatar in 2022. By the time the 2026 tournament begins, Messi will be 39 years old.

Ronaldo's situation appears different. The Portugal captain has continued to insist that his decisions will be based on his physical condition rather than his age, leaving open the possibility of playing beyond 2026.

Should he remain available for selection, Ronaldo could potentially feature at a World Cup hosted by Spain, Portugal and Morocco in 2030. The tournament holds special significance for Portugal as it will be one of the host nations.

For football supporters, the next World Cup could mark the final chapter of one of sport's greatest rivalries. While Messi is expected to make his farewell appearance in 2026, Ronaldo appears determined to keep writing his story for as long as his body allows.

The two superstars have combined for 13 Ballon d'Or awards, multiple Champions League titles and countless records, defining an era that many fans consider the greatest individual rivalry in football history.

Whether Ronaldo ultimately reaches the 2030 World Cup remains uncertain, but the prospect of seeing him compete at 45 continues to capture the imagination of football fans around the world.
