FIFA has scrapped group‑stage goal difference as the primary tiebreaker, replacing it with head‑to‑head records for teams level on points. The change means a side can clinch the top spot after just two matches, something that previously required a four‑point cushion. Organisers hope the new rule rewards direct results and reduces reliance on goal margins. Fans will notice the shift immediately.

Group A already illustrates the impact. Mexico won its first two games, sitting on six points, three ahead of South Korea. Because Mexico beat Korea, both teams cannot finish level on points, guaranteeing Mexico the group title despite a final match against the Czech Republic. The result lets Mexico rest players for a round‑of‑16 tie in Mexico City. South Africa remain in contention.

The rule also reshapes other groups. In Group C, Scotland can seal first place by beating Morocco if Brazil slips against Haiti; similar conditional scenarios exist from Groups D through L, where a win combined with another result can lock the top spot. Coaches now face strategic choices about squad rotation once qualification is mathematically secured. This could influence line‑up decisions in the knockout round.
