Five Premier League sides have joined Chelsea in leaving the proposed European Super League (ESL), while Man United supremo Ed Woodward is also said to be quitting and several key figures at clubs are under pressure.
News broke that City no longer wanted to be part of the multi-billion dollar league as it was revealed that Premier League rivals Chelsea are one of several members applying to leave the breakaway group less than 48 hours after its existence had been announced.
United, Liverpool, Tottenham and Arsenal are also leaving the ESL after an eventful day of widespread protests against a competition that now seems destined to fail to get off the ground.
Woodward, who used to work as an investment banker for JP Morgan, which is providing much of the vast backing for the league, has offered his immediate resignation at United, according to the Telegraph.
Other key figures in the ESL are now also said to be under immense pressure to consider their positions, including Real Madrid president Florentino Perez, who had claimed the competition would "save football", and Juventus' Andrea Agnelli, who is acting as vice-chairman.
Speaking earlier in the day, revered City coach Pep Guardiola appeared to criticise the new proposals for removing the element of competition by guaranteeing established large clubs qualification while making it harder for others to take part.
"I support my club. I love to be part of this club," he said, lamenting a situation he feels is "uncomfortable for the managers."
"As I said, I don't have all the information. If you ask me why these teams have been selected to play this hypothetical competition in the future… sport is not a sport when the relationship between effort and reward does not exist.
"It is not a sport if success is guaranteed or if it doesn’t matter when you lose.
"I have said many times I want a successful Premier League, not just one team at the top.
"I don’t know if the statement will change and four or five teams will be able to go up."
PSG and Bayern Munich have already said that they will not be joining the other 12 participants that had planned to leave the Champions League.
Potential broadcaster Amazon Prime also announced that it did not plan to screen the Super League.
There were chaotic scenes outside Stamford Bridge, where Chelsea supporters protested and then celebrated the news before fans took to social media to praise the developments and make calls for sanctions and dismissals over the botched rebellion.
