Paris Saint-Germain president Nasser Al-Khelaifi has acknowledged that he rejected an offer of €400m (£340m) to join the European Super League.
When the controversial plan was put forward last year, PSG were missing from the list of 12 clubs, allegedly turning down the opportunity at a time when many of their European rivals signalled their intention to form a break-away group.
Speaking on the matter in an interview with BBC Sport, Al-Khelaifi has accused those behind the plan of bringing "no stability" to the project, which Real Madrid president and face of the ESL Florentino Perez is still trying to put into action.
Al-Khelaifi said: "I could have taken the cheque for 400 million euros. They invited me. Then when I said no, they said they didn't invite me - that sums them up.
"The problem with ESL clubs is that they don't have stability. They don't have a long-term financial vision. They keep talking about their legal contract [with the Super League clubs].
"What they forget is football is a social contract, it's not a legal contract - they're waving around a piece of paper.
"Florentino Perez spoke to me at the Champions League game and said, 'We have to get a point where we can speak to you'. I was really tough with him. I said I was happy to talk, but if he was going to do stuff behind my back, I am not interested."
The structure of the ESL broke down when all six Premier League clubs withdrew from the project 48 hours after the official launch. body check tags ::
