For nearly two decades, football has revolved around Lionel Messi and Cristiano Ronaldo.
The 2026 FIFA World Cup, co-hosted by the US, Canada and Mexico, could see Messi headlining Argentina's title defence while Ronaldo looks to get the elusive trophy in his final attempt.
There's a chance fans could be treated to a Messi vs Ronaldo showdown at the World Cup, but it also depends on other results.
Argentina and Portugal's paths could cross in the quarter-finals if they both finish top of their groups, or in the Round of 16 if they finish as runners-up.
However, if one team wins their group and the other comes second, they can only face each other in the final.
Beyond results and trophies, the tournament will be remembered as a celebration of Messi and Ronaldo's longevity, rewriting football history and changing how players remain at the highest level.
Their rivalry has led to extraordinary numbers, countless trophies and endless debate over who is the greatest of all time.
Messi leads in Ballon d'Or awards with eight, compared to Ronaldo's five, and is the only player among the two to have won the FIFA World Cup.
Ronaldo is international football's all-time goalscorer with 143 goals.
Portugal manager Roberto Martinez praised Ronaldo's dedication, saying, 'Our captain sets an example in everything he does.'
