It’s decided by a pre-set bracket , not by randomly matching the “best” third-place team with the “worst” available opponent. For the World Cup-style format, the third-place qualifiers are ranked first, and then those qualifiers are slotted into fixed knockout combinations depending on which groups produce the top third-place teams.

How it works

  • All 12 third-place teams are ranked using tiebreakers: points, goal difference, goals scored, fair play, and then FIFA ranking if needed.
  • The top 8 third-place teams advance to the Round of 32.
  • Their opponents are determined by a predetermined matchup table that FIFA uses for each possible combination of qualifying third-place teams.
  • That means the bracket is fixed in advance, but the exact opponent depends on which groups supply the qualifying third-place teams.

Why it feels confusing

The tricky part is that the third-place teams are not paired one-for-one by rank alone. Instead, the tournament has to avoid rematches and preserve the structure of the knockout bracket, so the matchup depends on the full set of qualifying third-place teams.

Simple example

If a certain combination of groups supplies the eight qualifiers, then the bracket assigns those teams to specific Round of 32 slots. If a different combination qualifies, the third-place teams may be placed into different slots and face different group winners.

TL;DR: third-place teams are ranked first, then placed into a fixed bracket table that changes based on which groups’ third-place teams actually qualify.
