Inter Milan GM Beppe Marotta says they must learn from the Super League fiasco.
Inter were part of the breakaway before withdrawing their commitment yesterday.
Marotta told Sky Italia: "Let's start with the premise, this initiative was carried out by the 12 club owners in light of the situation of their individual clubs because of certain costs and uncertain revenues. This model of national and European football is an outdated model. It was necessary to find the possibility of inventing something, it was done in the light of a football system at risk of default.
"Let's talk about the whole scenario. Salaries cost 60% -70% of the budget, this model does not guarantee the future. We had to look for something to change."
Marotta continued: "The Super League was wrecked because important aspects such as the voice of the fans were underestimated, a real asset. The six English clubs have suddenly slipped away according to their logic.
"If this project has failed it means that some mistakes have been made along the way, this answer says it all, but the principles must be safeguarded.
"Respect for meritocracy and its fans is needed, a club has values to pursue, sport is an instrument of positive emulation."
