The report says head-to-head results now come before overall goal difference when teams finish level on points. If the tie remains, goal difference and goals scored in matches between the teams are considered before the wider group record.
That changes late-round calculations. A team may no longer need to chase a bigger overall winning margin if its direct result against a rival already gives it an advantage. Conversely, a poor head-to-head result can leave a side vulnerable even after a strong performance elsewhere.
The rule makes every meeting between direct qualification rivals more significant. Managers may approach those games with greater emphasis on avoiding defeat, not simply improving their goal difference.
The report also says referees can begin a visible five-second count when a player delays a throw-in. If the count expires, possession can be awarded to the opposition.
Sead Kolašinac reportedly lost possession in this way during Bosnia and Herzegovina’s match against Canada. The incident illustrates how a familiar time-management tactic can become an immediate turnover.
Throw-ins are often treated as low-risk restarts, but the stricter enforcement raises the cost of hesitation. Players must be ready before receiving the ball, while opponents can press knowing that delay may produce possession without a tackle.
Hydration interruptions reportedly last three minutes, with the lost time added at the end of each half. The report says matches have commonly carried at least five minutes of additional time per period.
That creates a longer closing phase, particularly in hot conditions. Substitutes, set-piece specialists and late pressing plans may become more important as matches move beyond the expected 90 minutes.
The next group-stage fixtures will show whether teams adapt quickly-or whether these management changes continue deciding moments that once passed almost unnoticed.
