Fifa president Gianni Infantino has given his backing to shock proposals to fast-track the expansion of the World Cup from 32 to 48 teams in time for Qatar 2022.
Infantino, who has promised major fresh investment into the world game as part of his re-election drive next year, said "we have to see if is possible" for the new format to be brought forward from 2026.
The proposal comes less than a week since he was forced to put plans on hold for a lucrative new Club World Cup and Nations League after intense European opposition.
Increasing the size of the World Cup so hastily would require Qatar to share 2022 hosting duties with neighbouring countries, presenting a potentially major diplomatic hurdle to overcome.
In 2026, USA, Canada and Mexico have agreed to combine forces to host 48 nations.
