Leaked Super League documents have revealed that Barcelona and Real Madrid were set to receive £52m more than the other founding clubs.
The Spanish giants were among 12 founding members of a breakaway competition that was announced on Sunday.
It was quickly hit with widespread criticism and huge fan backlash and less than 48 hours after its inception all six Premier League sides had pulled out.
The same text also stated that Barcelona and Madrid were set for bumper bonuses during the first two years of the tournaments.
Their extra windfall was set to come from the media revenue pot.
Both teams are in terrible financial situations with the Catalans in £1bn of debt and Madrid also struggling.
Los Blancos supremo Florentino Perez, who was set to be the Super League’s president, claims their competition was made to save football.
His comments have been heavily criticised from those who believe he was acting in Madrid’s best interests.
“Whenever there is a change, there are always people who oppose it. We are doing this to save football at this critical moment,” Perez said on Spanish TV show El Chiringuito de Jugones .
“Audiences are decreasing and rights are decreasing and something had to be done. We are all ruined. Television has to change so we can adapt.
“Together we have lost €5billion,” he added of the top clubs’ alleged losses. “In two seasons Madrid have lost €400m.
“When you have no income other than television, you say that the solution is to make more attractive matches that fans from all over the world can see with all the big clubs, and we came to the conclusion that if instead of having a Champions League we have a Super League we would be able to alleviate what we have lost.”
