The loss-making museum was a pet project of Sepp Blatter who stepped down as FIFA president in 2015.
FIFA has gone on the offensive amid ongoing speculation about a European Super League, insisting any breakaway by leading football clubs “would not be recognised by either FIFA or the respective confederation”.
It said in a statement on Thursday players would risk being banned from the World Cup and other big tournaments if involved.
“Any club or player involved in such a competition would as a consequence not be allowed to participate in any competition organised by FIFA or their respective confederation,” the statement said.
It was signed by FIFA President Gianni Infantino along with the heads of all six continental confederations including UEFA.
In October, outgoing Barcelona President Josep Maria Bartomeu dropped a bombshell in a statement announcing his resignation, as he also claimed the club had accepted a proposal to play in “a future European Super League”.
That followed reports in the United Kingdom that negotiations were nearing conclusion for the creation of a “European Premier League” of 18 clubs, backed by $6bn of financing from big banks.
However, those reports came with discussions still ongoing about the future format of the UEFA Champions League, the world’s most lucrative and prestigious club competition.
In November 2018, German magazine Der Spiegel – citing leaked documents – reported that Spanish giants Real Madrid had been making plans for a Super League to feature the continent’s biggest clubs.
UEFA President Aleksander Ceferin denounced it as a “selfish and egotistical scheme” after Madrid President Florentino Pérez was reportedly seeking financiers to back the project.
The reports were seen as trying to put pressure on UEFA during talks to make changes to the Champions League that would favour elite clubs.
The UEFA negotiations restarted after initial talks stalled in 2019. The controversy was fuelled by a club-backed proposal that would help successful teams retain their Champions League places.
FIFA and UEFA reaffirmed on Thursday the importance of promotion and relegation giving access to all clubs as a key principle of football.
“Participation in global and continental competitions should always be won on the pitch,” the FIFA-led statement said.
Meanwhile, FIFA remains focused on plans for an expanded, 24-team Club World Cup, championed by Infantino.
The competition was due to take place for the first time this year in China but was put back to a later date after Euro 2020 and the Copa America were postponed to June and July 2021 because of the coronavirus pandemic.
The delayed 2020 edition of the Club World Cup will go ahead next month in its existing format, involving only the champions of each confederation – minus New Zealand’s Auckland City of Oceania who withdrew due to complications caused by the pandemic – plus the champions of the host nation, Qatar.
“As per the FIFA and confederations statutes, all competitions should be organised or recognised by the relevant body at their respective level, by FIFA at the global level and by the confederations at the continental level,” FIFA said.
“In this respect, the confederations recognise the FIFA Club World Cup, in its current and new format, as the only worldwide club competition while FIFA recognises the club competitions organised by the confederations as the only club continental competitions.”
