Galatasaray chairman Unal Aysal has called for a European super league to be created as soon as possible.
There has long been talk about the potential of a newly-formed league consisting of the best clubs from across the continent.
Four years ago Arsenal manager Arsene Wenger predicted such a league would become reality within a decade, although the idea has yet to get off the ground.
Galatasaray chief Aysal reignited the debate at the Leaders in Football conference on Thursday, calling for the creation of a 20-strong league.
"I think it is the future of football," he said. "It has to be created, not after 10 years but as soon as possible.
"Football is a big industry, a growing industry, and a European super league will bring a lot of support and also energise football in general.
"I think it could be 20 big teams, for example, in Europe, with the last three, four or five teams can change every year.
"I think it can be operated in a proper way in order to make it effective and useful to European football and also to bring new horizons in football."
Aysal would prefer the league to be controlled by clubs rather than UEFA, but would welcome the governing body starting the initiative.
The Turk was keen not to mention potential English involvement, but was more forthcoming when asked about interest from the Premier League in one of his players.
