The ECA is expected to gain a higher revenue share than clubs from other continents because of the importance of their clubs to the competition, and because those members will be unable to play lucrative overseas pre-season tours.
Chelsea, Manchester City, Bayern Munich, Borussia Dortmund, Paris St-Germain, Inter Milan, Juventus, Atletico Madrid, Benfica, Porto and FC Salzburg are all represented by the ECA.
Real Madrid are not part of the ECA because of their ongoing support for a breakaway European Super League.
The ECA has committed to supporting the Club World Cup until at least 2030 through a memorandum of understanding signed in 2023.
Multiple sources from outside Europe have expressed their support both publicly and privately for the competition, although they remain in the dark about how much they will receive for participation.
Fifa president Gianni Infantino said in December: “Whatever Fifa does, [it] has to be global.
“[Fifa] has to involve the globe. [Fifa] has to give opportunities and chances to [everyone] all over the world, and the Club World Cup is doing exactly that.”
Fifa, meanwhile, will not make a single dollar of profit from the tournament and says it will reinvest the entire $1bn into global club football.
There will be a Fifa Council meeting to update members on the progress of the tournament, which will be hosted in 12 stadiums across 11 US cities during the month-long summer event.
