However, a joint statement confirms the only such tournament that will receive official recognition is the Club World Cup, and any player involved in a breakaway event would be barred from being involved in official competitions.
"Any club or player involved in such a competition would as a effect not be allowed to participate in any competition organised by FIFA or their respective confederation", continued the statement, signed by FIFA president Gianni Infantino along with the heads of all six continental confederations - Asia's Shaikh Salman bin Ebrahim Al Khalifa, acting Confederation of African Football leader Constant Omari, Concacaf's Victor Montagliani, Conmebol's Alejandro Domínguez, Oceania's Lambert Maltock and last but very much not least, UEFA president Aleksander Čeferin.
Any club or player involved in such a competition would as a outcome not be allowed to participate in any competition organised by Federation Internationale de Football Association or their respective confederation, the joint statement said.
The Super League has received widespread criticism from some of football's most influential figures including UEFA president Aleksander Ceferin, who described the mooted division as "one of the most boring projects in the world". In comparison, UEFA most recently reported making a combined 3.25 billion euros from selling the rights to the Champions League, Europa League and UEFA Super Cup.
FIFA's insistence that any players involved in a breakaway league would be ineligible for global competitions would also likely face legal challenges, should such a league come into existence.
Real Madrid and Barcelona were linked a year ago with planning a breakaway competition inviting famous clubs to enter and increase their own wealth from global broadcasting deals by playing each other more often. Controversy was fueled by a club-backed proposal that would help successful teams retain their Champions League places. For months now, they have watched on as the most powerful clubs in the world have talked among themselves about the future of football post-2024, when European football's current broadcast and sponsorship deals expire.
Speaking about the proposed Super League in the Swiss media last October, Infantino said: "For me, I'm not interested in Bayern versus Liverpool, but Bayern versus Boca Juniors from Buenos Aires".
That effectively means they would bar players participating in the Super League from taking part in the World Cup.
"This is the foundation of the model and the main reason for football's success".
The Club World Cup, now an annual tournament with seven teams, could become a four-yearly event featuring 24 clubs instead.
"Participation in global and continental competitions should always be won on the pitch", the statement read.
