Fifa president Infantino called it an eloquent and detailed proposal with 166 national federations voting in favor with 22 voting against
Fifa will carry out a feasibility study on holding the World Cup and the women's World Cup every two years after backing a proposal at its annual congress Friday.
The two competitions are currently held every four years but the Saudi Arabian Football Federation put forward a proposal for a study of the impact of switching to every two years.
Fifa president Gianni Infantino called it an "eloquent and detailed proposal" with 166 national federations voting in favor with 22 voting against.
Speaking after the congress, Infantino told reporters that the study would look at the competitions within the context of the review of the overall international match calendar.
But Infantino questioned whether the current system of regular qualifiers throughout a year ahead of a continental championships and World Cups was the best model.
