The proposed amendments also include an overhaul of the group stage into a single table, as opposed to the current groups of four clubs, with teams playing ten matches each, and a play-off round introduced before the last-16 phase.
The alterations will be decided upon at UEFA’s executive committee on Monday morning, with top officials at the governing body set to meet in Switzerland.
FIFA has criticised the creation of a new breakaway League, stating that the move is not in accordance with the governing body’s values, adding that it will do “whatever is necessary to contribute to a harmonised way forward”.
A FIFA statement read: “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 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 interests of football.”
A statement from the ECA, (European Club Association), released on Sunday evening, said it “strongly opposed” the “closed Super League model” which has been reported on. The organisation has made clear its desire to work with UEFA on amending the structure of European club football from 2024 onwards.
There have been reports of a plan for a breakaway league for a number of years and the speculation returned in January with several media reports that a document had been produced outlining the plans for a 20-team league.
The Premier League, and the organisation’s CEO Richard Masters, have condemned the European Super League concept, and Masters has written to all 20 clubs to indicate the League’s opposition to the project.
“We do not and cannot support such a concept,” Masters’ memo read.
Under Premier League rules, which all clubs sign up to, a club needs “prior written approval” from the Premier League Board to enter another competition not including the Champions League, Europa League, EFL Cup, FA Cup, Community Shield, or competitions sanctioned by the county association of which it is a member.
The FA have not ruled out taking legal action over the proposals and the governing body has indicated that it will block any requests from teams to join such a league.
The PFA, the Football Supporters’ Association, a number of supporters’ clubs, and prominent figures in the game, including former Manchester United manager Sir Alex Ferguson and Gary Neville, have voiced their disapproval of the project.
Earlier on Sunday, UEFA released a joint statement, personally sanctioned by the governing body’s president Aleksander Ceferin, with the FA, Premier League, La Liga, and Serie A, as well as the Spanish and Italian football federations, which blasted the plans.
UEFA stressed that Europe’s top national football governing bodies and leagues will remain united in opposing the “cynical” initiative, and will use all methods available to them, including legal action, to prevent the scheme from being put into practice.
European football’s governing body has also said clubs involved will be prevented from competing in “domestic, European or world level” competitions and that players may be stopped from representing their countries. Meanwhile, UEFA praised sides in France and Germany for not agreeing to join the European Super League.
“Every club and player participating in the Super League could be banned from all UEFA and FIFA competitions, European or International level,” UEFA said.
