Clubs playing in the Super League could be banned from all domestic competitions, and players would be banned from international tournaments, if the competition goes ahead.
On Sunday night, a joint statement by 12 of Europe's biggest clubs confirmed their plans for a breakaway 'Super League' competition.
The Premier League's 'big six,' along with three sides from Serie A and three from La Liga, were the founding clubs to have signed their name to the new competition, with three more clubs potentially joining.
Instead of replacing the domestic leagues, the new competition is set to be played in midweek and would therefore replace the Champions League, however it won't be that simple.
In their statement on Sunday, European footballing governing body UEFA confirmed that teams would face bans from domestic competitions, whilst players involved in the Super League would miss international tournaments.
"As previously announced by FIFA and the six Confederations," the statement reminded the 12 clubs involved, "the clubs concerned will be banned from playing in any other competition at domestic, European or world level, and their players could be denied the opportunity to represent their national teams."
UEFA have also threatened to sue the clubs involved up to €60 billion!
Whilst UEFA took an extremely harsh stance in their statement, FIFA didn't go quite as far as threatening bans, although they did claim they stood with UEFA's stance.
"In view of several media requests and as already stated several times, FIFA wishes to clarify that it stands firm in favour of solidarity in football and an equitable redistribution model which can help develop football as a sport, particularly at a global level, since the development of global football is the primary mission of FIFA.
"In our view, and in accordance with our statutes, any football competition, whether national, regional or global, should always reflect the core principles of solidarity, inclusivity, integrity and equitable financial redistribution. Moreover, the governing bodies of football should employ all lawful, sporting and diplomatic means to ensure this remains the case.
"Against this background, FIFA can only express its disapproval to a "closed European breakaway league" outside of the international football structures and not respecting the aforementioned principles.
"FIFA always stands for unity in world football and calls on all parties involved in heated discussions to engage in calm, constructive and balanced dialogue for the good of the game and in the spirit of solidarity and fair play. FIFA will, of course, do whatever is necessary to contribute to a harmonised way forward in the overall fairness of football."
