FIFA moved a step closer on Friday to expanding the 2022 World Cup in Qatar to 48 teams and hopes to confirm the plans in June if a suitable co-host can be found.
An internal feasibility study supporting the expansion, which is being strongly pushed by president Gianni Infantino, was given full backing by the FIFA council in Miami.
A final decision will now be taken in Paris on June 6 after FIFA and Qatar jointly submit the names of potential co-host nations to the governing body's Congress.
Infantino, who also confirmed a new Club World Cup with 24 teams will begin in 2021 to replace the Confederations Cup, told a press conference: "You have in front of you a happy FIFA president.
"I am always happy but especially today because we have taken some important decisions.
"We came to conclusion, yes it's feasible to move from 32 to 48 teams at the World Cup provided certain conditions are met.
"We have the duty to look into it, 90 percent are in favour of an increase but it's not as easy as that. We have to analyse matters carefully and we are working closely with Qatar."
