FIFA president Gianni Infantino has not ruled out increasing the number of teams participating at the 2022 World Cup to 48.
Qatar will host the next edition of football's global event after beating off competition from the United States, South Korea, Japan and Australia.
Since 1998 there have been 32 teams competing at the World Cup, and that is expected to be the same in three years' time.
However, from the 2026 tournament in the USA, Mexico and Canada there will be an extra 16 nations present after FIFA voted through to expand the format in January 2017.
Infantino was a supporter of the expansion and the president of football's world governing body would be open to bringing the changes forward.
"The World Cup will take place in Qatar with 32 teams. Obviously, if we can increase it to 48 teams and make the world happy we should try it," Infantino told the Dubai International Sports Conference on Wednesday.
"If you think it's a good thing to have 48 teams in the World Cup, why not try four years before, that's why we are analysing whether it's possible to have 48 teams already in 2022
"If we can accommodate some of the neighbouring countries in the gulf region which are very close by to host a few games in the World Cup this could be very beneficial for the region and the entire world.
"There are tensions in this particular region and it's up to their respective leaders to deal with that but maybe it's easier to talk about a joint football project than more complicated things.
"If it can help all the people in the Gulf and all the countries in the world develop football and bring a positive message to the world about football, then you should give it a try."
