The 23rd edition of the FIFA World Cup could feature a long-awaited encounter between Argentina’s Lionel Messi and Portugal’s Cristiano Ronaldo, two of the greatest rivals in modern football. Both stars are set to appear in their sixth World Cup, having played in every tournament since 2006.

Many believe the 2026 World Cup will be their last, potentially offering fans a direct duel between the legends. Argentina, led by 38-year-old Messi, is in Group J alongside Algeria, Austria, and Jordan. Portugal, captained by 41-year-old Ronaldo, is in Group K with DR Congo, Uzbekistan, and Colombia.

If both teams top their groups, they could meet in the quarterfinals, provided they win their Round of 32 and Round of 16 matches. Should they finish second, a clash could occur as early as the Round of 16, though this path is tougher, with Argentina likely facing Spain and Portugal meeting Croatia. The expanded 48-team format also leaves open the possibility of a final showdown.

Messi holds a clear edge in World Cup achievements, having led Argentina to victory in 2022 and to the final in 2014. Ronaldo’s best finish was fourth place in 2006. Individually, Messi has played a record 26 World Cup matches, scoring 13 goals and providing 8 assists, while Ronaldo has 22 appearances with 8 goals and 2 assists.

The two have met twice in international friendlies: Argentina won 2-1 in Geneva in 2011, with both stars scoring, while Portugal won 1-0 at Old Trafford in 2014. At club level, they faced off 35 times, mostly in El Clásico, with Messi winning 16, Ronaldo 10, and 9 draws.
