Any move to form a breakaway super league involving Europe's top sides would lead to "war" between the clubs and UEFA, according to a presidential candidate for the governing body.
Alexander Ceferin, who heads the Slovenian FA and holds more than 20 pledges of support for his candidacy, claims that any closed super league is "out of the question".
"One of the main issues awaiting the next UEFA president is relations to the big clubs," he told BBC Sport.
"My firm opinion is that some kind of closed super league with just a few clubs in, without the possibility for the others to enter, is out of the question. It will mean a kind of war between UEFA and the clubs.
"If they want more revenues we should work on it. It is possible. The Champions League is the best sports product in the world, for sure. But it doesn't generate the most money. So we should include [the clubs] more."
Talks involving leading European clubs and UEFA are ongoing, with a Champions League format revamp under discussion, and a decision could be announced as early as Friday.
