They have not met at a World Cup since 1990. Brazil top Group C, Argentina top Group J, and the brackets keep them apart through the quarterfinals. Earliest possible meeting is the semifinal. The probability sits at roughly 14 to 18 percent. If it happens, it would be the most-watched football match in tournament history.
Probability split based on team strength, recent form, and tactical fit.
How will this match end?
Lionel Scaloni has built one of the most disciplined international setups of the past decade. The 4-4-2 with Lautaro Martinez and Julian Alvarez is a press-from-the-front machine that recovers high and channels possession through Lo Celso and Mac Allister. Brazil under Dorival Junior remain individually superior in the final third, but the structural gap behind that has narrowed.
Vinicius and Rodrygo on the wings, Raphinha or Endrick centrally, and a creator (Bruno Guimaraes or Lucas Paqueta) feeding them. Argentina counter with a midfield triangle that has won three of the last three meetings between these sides. Whoever controls the central third for longer wins the match.
Emiliano Martinez is in a different conversation than Alisson at this stage of his career. The Aston Villa keeper has saved penalties in two of the last three Argentina knockout shootouts, including the 2022 final. Brazil have not had a tournament-defining goalkeeper since Dida.

Carlo Ancelotti has six months to turn Brazil from talented underachievers into champions. The squad is there. The bracket is fair. The pressure is enormous.
