Barcelona boss Joan Laporta has confirmed that the club's members will have the final decision over their participation in the proposed European Super League.
The planned tournament, that was only announced on Sunday, has quickly descended into chaos amid universal criticism.
Initially, 12 Founding Members confirmed their inclusion into a tournament which would have guaranteed some of the continent's biggest clubs entry, regardless of performance.
Governments, governing bodies and supporters have all condemned the proposals, with protests taking place at a number of stadiums.
It has been reported that Premier League pair Chelsea and Manchester City are both preparing to pull out of the tournament, while there is also a belief Atletico Madrid will do the same.
And now Laporta, who was only named president earlier this year has admitted that the La Liga giants will only move forward after a vote between all members.
In a statement, he confirmed: "Barca will not enter the Super League without the approval of the Assembly of Members. It is they who decide, it is their club."
It now seems almost certain that other major clubs will follow, and it is looking increasingly unlikely that the Super League will become a reality.
Real Madrid president Florentino Perez spoke passionately about the project only on Monday night, claiming that the move was for the good of football.
"We are doing this to save football at this critical moment," Perez told Spanish TV show El Chiringuito de Jugones.
"If we continue with the Champions League there is less and less interest and then it's over.
"The new format which starts in 2024 is absurd. In 2024, we are all dead."
Plans for a revamped Champions League were also approved on Monday, which will see 36 teams enter that tournament.
Perez added: "In the '50s, it was a similar situation. Uefa and Fifa went against the new European Cup, but that competition changed football."
