We're not sure if you've noticed, but Lionel Messi and Cristiano Ronaldo are both playing at this World Cup.
The two megastars of their generation have a long and storied rivalry with one another, rooted primarily in their time as the star players for Barcelona and Real Madrid respectively.
But is there any chance we might get to see them face off one more time - and if so, what would it take to set up a meeting between Argentina and Portugal?
When Argentina and Portugal could meet at the 2026 World Cup
The pair had a near-monopoly on the Ballon d'Or between between 2008 and 2021, with Luka Modric the only player to break their dominance in that spell.
The pair's most ardent/deranged supporters have argued long and hard as to which of the two can lay claim to being the greatest player of their era or possibly of all time, despite the fact that it's quite obviously Messi.
There are a few different routes that could lead to a meeting between Portugal and Argentina in the knockout stage of the World Cup.
The most straightforward would be for Portugal to win their group by beating Colombia on Saturday afternoon. That would put them in the same half of the draw as Argentina, and they would meet in the quarter-finals on Saturday, July 11 in Kansas City if both sides made it that far.
If Portugal fail to beat Colombia and finish as group runners-up, however, then they would go into the other half of the bracket. They would meant Portugal would be unable to meet Argentina unless both were involved in either the final at MetLife Stadium in New Jersey on Sunday, July 19; or the third-place play-off at Miami's Hard Rock Stadium the day before.
It is extremely unlikely that Portugal will end up coming third in Group K: they would need to lose to Colombia while DR Congo beat Uzbekistan, and with the scorelines aligning in such a way that the African side overturn a six-goal swing in goal difference.
But if that were to happen, Portugal would face the winners of Group L in the next round - and thus be in Argentina's half of the draw. The two sides could then meet in the semi-finals at the Mercedes-Benz Stadium in Atlanta on Wednesday, July 15.
Messi and Ronaldo have faced off 36 times over their careers, first going head-to-head in Manchester United's Champions League semi-final victory over Barcelona in 2008.
Messi's Barca got retribution in the final a year later, and the Argentinian holds the better record in meetings between their various sides with 16 wins, nine draws and 11 defeats. Their last meeting came in 2020, when Barcelona faced Juventus in the Champions League group stage.
However, they have only faced each other on the international stage twice before.
Argentina won a friendly 2-1 in 2011, with Messi scoring a late winner after Ronaldo had equalised for Portugal.
Portugal won the second meeting 1-0 in another friendly at Old Trafford in 2014, with their injury-time winner coming after both players had been subbed off at half time.
