"Our European Super League is the UEFA Champions League!" ECA chairman Karl-Heinz Rummenigge said in a statement. "We are very happy with the current competitions and our extremely fruitful collaboration with UEFA. We will continue to work together with UEFA, and this beyond 2018."
At the Leaders in Football Conference, Aysal said the plans for the league were not fully developed.
"The system has to be put in place, either by UEFA or by the clubs themselves, then we will decide if a breakaway will be a necessity or not," Aysal said. "It's not yet totally elaborated and prepared and put on the paper. But it is a concept that is under discussion for a few years."
Aysal said unnamed financial backers are already being lined up.
"I spoke personally with some sponsors we are working with," he said. "They looked at the idea very positively. International companies. Two of them were big brands."
