Speaking to Reuters at an event in Brussels, Rosell agreed that a league in which the big two, the world's richest clubs by income, were not always so dominant would be more compelling.
"No no it's something I fully agree with," Rosell said when asked if it would not be better to follow the English Premier League model, where three or four teams scrap for the title and the top dogs slip up against lesser sides much more regularly.
"We have to sit down with the Spanish teams and look for solutions on that yes, I agree," he added.
Clubs like Atletico Madrid, Sevilla and Espanyol have been trying to persuade Barca and Real to share TV money more equitably and have even accused the big two of "stealing".
"This is exactly one of the things we have to discuss with the rest of the clubs," Rosell said when asked about the television revenue issue.
"In fact we had some meetings in the past, last year, and as from 2014-15 we decided a new distribution of TV income for Spain," he added, without elaborating.
"So yes we are improving on that and probably in the future something will change."
