The World Cup will be expanded to host 48 teams, up from 32, Fifa has decided, reports BBC Sport.

An initial stage of 16 groups of three teams will precede a knockout stage for the remaining 32 when the change is made for the 2026 tournament.

The sport's world governing body voted unanimously in favour of the change at a meeting in Zurich on Tuesday.

The number of tournament matches will rise to 80, from 64, but the eventual winners will still play only seven games.

The tournament will be completed within 32 days. The changes mark the first World Cup expansion since 1998.
