What happened: FIFA has changed how group standings are decided at the expanded 48-team World Cup, making head-to-head record the primary tie-breaker ahead of goal difference. With one round of group matches still to play, the shift has already fixed eight teams into set positions, turning several fixtures that could have been decisive into dead rubbers. The change arrived suddenly and reverses the format that produced the chaotic, end-to-end finishes of 2022.

Why it matters: Ranking head-to-head above goal difference removes the late jeopardy that made final-round group games compelling, letting confirmed qualifiers rest players and rotate squads. Critics argue it also raises sporting-integrity questions, since it can give one result disproportionate weight over another within the same short group. It runs counter to FIFA's stated push to keep four-team groups precisely for their drama, and to its marketing of the tournament as elite entertainment.

What to watch: Watch the final round of group fixtures for second-string lineups from sides already locked in, and whether the still-live groups deliver the late tension the format was designed to create.
