Nasser Al-Khelaifi, the PSG president, has hit out at Barcelona, Real Madrid and Juventus for leading the failed European Super League project.
"Football has been around for years and years. The Super League did not have at heart to defend the interests of football," the PSG ruler told AFP.
"You can envisage changes but not break the tradition that every club can hope to achieve their dreams.
"All teams must have the opportunity to take part in the biggest competitions one day, and while remaining under the wing of UEFA.
"The Champions League is a very strong brand that must be preserved, but we must always be able to adapt to the market, and this is true for all competitions, domestic or international."
