Former Real Madrid GM Jorge Valdano believes clubs like Manchester United and Chelsea will soon be competing in a new European League.
Valdano, who was ousted in May after losing a power battle with Real coach Jose Mourinho, said the gap between the wealthy pair and the rest was likely to get bigger.
"In the future Madrid and Barcelona will have to look to teams that are going at the same speed, and that will lead to a European league," he told Cadena Ser radio.
"Before I defended Real Madrid's interests but now I see things from a different perspective," the former Real and Argentina player added.
"The gap between the big two and the rest is getting ever larger. If you look to the future you have the feeling that it will only get worse.
"Two teams which have the rest of the world as their market and the others only their local community.
"There will come a time when that won't be convenient for the two big clubs either."
