Biggest change is moving to every four years, and of course how many teams get in.
What does it look like?
Currently the Club World Cup runs once a season and features the winner of the Champions League in each of the respective six footballing confederations, as well as the winner of the host nation's domestic league (in this year's case, Qatar).
But in 2024, FIFA will scrap that model. Instead, the tournament will grow from featuring seven teams to 24, and run every four years.
Similarly to the international World Cup, the teams will be split into eight groups of three teams - with the winners of each group advancing to the knockouts, which will begin at a quarter-final stage.
The tournament will take place between June and July - when the Confederations Cup would usually be held, with FIFA deciding to abandon that tournament due to the lack of interest in it.
How do you qualify for the Club World Cup?
As it stands, FIFA have yet to confirm how you will qualify for the tournament (great planning guys) but according to Reuters, qualification will be based on a team's performance in their continental competitions over the course of the last four seasons.
While the official number of teams who can qualify from respective confederations has yet to be confirmed, it is likely that the 24 teams will consist of:
Eight European teams
Six South American teams
Three African teams
Three Asian teams
Three North/Central American teams
One Oceanic team
