Paris Saint-Germain are the latest European behemoth to distance themselves from the Super League.
While their name was absent from the list of founding members revealed on Sunday, it was widely anticipated the French champions would be late adopters of the proposal.
However, PSG chairman Nasser Al-Khelaifi has given a firm rebuke of the Super League, following his re-election to the UEFA Executive Committee.
"Paris Saint-Germain holds the firm belief that football is a game for everyone," said the head of Qatar Sports Investments.
"I have been consistent on this since the very beginning.
"As a football club, we are a family and a community; whose fabric is our fans - I believe we shouldn't forget this.
"There is a clear need to advance the existing UEFA competition model, presented by UEFA yesterday and concluding 24 months' of extensive and collaborative consultation across the whole European football landscape.
"We believe that any proposal without the support of UEFA - an organisation that has been working to progress the interests of European football for nearly 70 years - does not resolve the issues currently facing the football community, but is instead driven by self-interest.
"Paris Saint-Germain will continue to work with UEFA, the European Club Association and all stakeholders of the football family - based on the principles of good faith, dignity and respect for all."
Joining Al-Khelaifi on the UEFA Executive Committee in representing the European Club Association (ECA) is Karl-Heinz Rummenigge.
The Bayern Munich CEO removed the Bavarian giants from Super League conversations on Monday.
"I don't think the Super League will solve the European clubs' financial problems caused by COVID-19," Rummenigge said.
"Rather, all clubs in Europe should work in solidarity to ensure that the cost structure, in particular the players' salaries and agents' fees, are adjusted to the income in order to make European football more rational."
