The proposed Super League was announced on April 18th last year, although nine of the competitions' 12 founding clubs moved to renounce the idea within days after it provoked a fierce backlash from across the footballing world.
However, Madrid, Barca and Juve remain committed to the project, with Bianconeri president Andrea Agnelli reportedly keen to kick-start a new proposal.
Speaking at the Financial Times' Business of Football Summit in London, at which Agnelli was present, the UEFA president has now hit out at the clubs' owners for discussing the return of the controversial competition during the midst of Russia's invasion of Ukraine.
"First they launched [this] nonsense idea in middle of a pandemic," Ceferin said of the club owners. "Now we are hearing they are launching another in a war.
"They must live in a parallel world."
Ceferin has previously labelled Agnelli, as well as the Spanish giants' presidents Florentino Perez and Joan Laporta, as "incompetent", and accused them of trying to "kill football".
Meanwhile, Ceferin also spoke about the sporting sanctions being placed on Russia in the aftermath of the invasion on Ukraine.
FIFA and UEFA have moved to expel Russian teams from its competitions, including the upcoming Women's European Championships in England, for which Russia had qualified, while St Petersburg has been stripped of this season's Champions League final.
The governing body on Friday announced that Ceferin is the only candidate for the role for the elections that will be held in Lisbon on April 5.
Ceferin took over as UEFA president in September 2016 and started a new four-year term in February 2019.
The Slovenian's tenure will be extended to 2027, with the deadline for candidates to oppose him having passed on Thursday.
Noel Le Graet, the president of the French Football Federation, faces a challenge to keep his seat on the FIFA Council.
Portugal FA chief Fernando Gomes will be hoping to secure the votes to take Le Graet's place.
Meanwhile, the deadline for the submission of candidatures for seats on the UEFA Executive Committee is February 5.
FIFA, led by chief of global football development Arsene Wenger, has been promoting the idea for the World Cup to shift format and take place every two years.
FIFA reported to its member associations at their global summit on 20 December that the changes would make football $4.4billion richer over the first four-year cycle.
That figure would then climb to $6.6billion, according to FIFA president Gianni Infantino, if each confederation also switches its regional competition to become biennial, while FIFA claimed its members were largely in support of the plans.
But UEFA, along with South America's CONMEBOL, continue in their staunch opposition to the proposed alterations to world football's showpiece event.
"Europe and South America are against [the plan] and those are the only [continents with] World Cup winners in history," Ceferin told reporters at the Expo 2020 Dubai Fair on Thursday.
"The problem is that the World Cup has to be every four years to be interesting.
"Second, if it would be every two years, it would cannibalise women's football because it would be at the same year as the women's football [World Cup', other sports, the Olympic Games - many mistakes.
"It's simply a bad idea and it will not happen because it is a bad idea, not because we are opposing it."
Ceferin's comments come after the two governing bodies clashed ahead of FIFA holding its global summit with national associations earlier in December.
FIFA published results from a study that claimed the majority of football fans would like to see more frequent World Cups. UEFA, however, said an independent survey called proposals "alarming" just hours before.
The International Olympic Committee (IOC) is also part of a growing list of opposition, which includes Kylian Mbappe and Robert Lewandowski after the pair raised concerns earlier in the week, all of whom fear the impact of the changes on the world's sporting calendar.
"Why are the Olympic Games every four years? Because it's an event that you have to look forward [to], that you have to wait [for], and you have to enjoy it," Ceferin added.
FIFA president Gianni Infantino last week indicated the world governing body had dropped the project, which had drawn strong criticism from European and South American authorities in particular.
Infantino said FIFA had never proposed the change to the tournament that has taken place every four years since the first edition in 1930.
But Infantino had been seen by many as a cheerleader for the switch, making a widely criticised claim in January that opportunities delivered by a World Cup every two years could provide impetus for African migrants to avoid treacherous crossings to Europe, suggesting they could avoid "death in the sea".
Ceferin told a news conference on Thursday: "We are happy FIFA ordered that it is finally off the table, the biennial World Cup.
"Formally it was not proposed by FIFA, but it was encouraged by FIFA. It's good they've listened to the football community.
"For me, it's very good that this project that is more or less a nonsense is off the table."
Former Arsenal manager Wenger, as FIFA's chief of global development, had been the main advocate for the biennial World Cup, promoting the concept widely ahead of a possible vote and nailing his colours firmly to the mast.
Infantino claimed the alterations would yield significant financial returns if the plans were approved, with a boost of $4.4billion in the first four-year cycle of a new international calendar, which would climb to $6.6bn if each confederation also switched its regional competition to become biennial.
A vote now appears highly unlikely to happen in the near future, and Ceferin questioned whether there should be any other major tournaments added to the international calendar.
"About new tournaments, I don't think there's much time for new competitions, but let's speak about it and let's see," Ceferin said. "For now, we didn't discuss it."
Ceferin said UEFA would take a decision "very soon" on Russia's possible involvement in the Women's European Championship, which begins in July and will be staged in England.
Despite Russia's invasion of Ukraine, which has led the country to be widely ostracised, a final ruling has yet to be taken on whether the women's football team should be allowed to take part.
The men's team were swiftly thrown out of the World Cup by FIFA, denied a place in a play-off to reach the Qatar 2022 finals.
Ceferin said: "There is a court case at the Court of Arbitration for Sport in the case of the Russian Football Union. We expect some information from there as soon as possible, but we know we are in a hurry to decide about this issue. We know the Euro is very soon and that we'll have to take the decision soon, but we need some more information."
Asked whether Russian football authorities should be expelled by UEFA, Ceferin said there were "considerations about many things these days".
Russia has bid to host the Euro 2028 or Euro 2032 finals, in a move that has been met with widespread disbelief.
Ceferin will be aware of that sentiment and said of Russia's bid: "We are discussing it, and you will have the answer very soon."
Britain's longest-reigning monarch passed away at her home in Balmoral, just months on from her Platinum Jubilee.
News broke amid Arsenal's early Europa League kick-off against Zurich, with the Gunners returning to the field for the second half in black armbands and a minute's silence held before play resumed.
Manchester United and West Ham's subsequent European commitments were prefaced by a minute of silence and tributes to the Queen too, and Ceferin offered his condolences.
"UEFA and European football are truly saddened by the passing away of Her Majesty Queen Elizabeth II, one of the world's most-respected figures," he stated.
"Our thoughts are with her family and the President of the English Football Association Prince William, as well as with the citizens of the United Kingdom and Commonwealth realms."
Ukraine was invaded by Russia last week and the fighting continues to escalate.
Millions of people are seeking refuge in neighbouring countries, and UEFA's Foundation for Children has pledged €1million in aid.
The UEFA foundation has also promised to provide an emergency fund of €100,000 to assist children and refugees fleeing into Moldova.
"Children are very vulnerable during conflicts and it is our duty to help defend their fundamental rights and their health," said Ceferin, chairman of the foundation's board of trustees.
"Thanks to the solidarity of European football and the support of our partners, we will be able to provide some of the assistance that children urgently need in Ukraine and in neighbouring countries."
UEFA confirmed the emergency fund of €100,000 will be provided to the Football Association of Moldova, which is working alongside humanitarian organisations. Provisions such as medicines and supplies to children's hospitals within Ukraine are included in the package.
UEFA set up its Foundation for Children in 2015 to help children and defend their rights, as well as provide support to their health and education.
In response to Russia's invasion of Ukraine, UEFA last week stripped St Petersburg of the right to host this season's Champions League final, which will instead be held in Paris.
UEFA and FIFA have also banned all Russian national and club teams from competing in any of their tournaments.
UEFA's executive committee approved new club licensing and financial sustainability regulations at its meeting in Nyon as the first major reform since financial regulations were imposed in 2010.
The alterations focus on "solvency, stability and cost control" to promote financial sustainability, with the "squad cost" regulations – which come into place from June 2022 – limiting the spending of clubs.
Clubs will only be able to spend up to 70 per cent of revenue on wages, transfers and agent fees, with breaches resulting in "pre-defined financial penalties and sporting measures".
UEFA president Aleksander Ceferin said the game, hit hard by the COVID-19 crisis, needed to be prepared in case of "any potential future shock".
In terms of solvency, there will be greater protection for creditors – and punishments for late payers – with no overdue payables towards football clubs, employees, social and tax authorities and UEFA.
UEFA revealed further changes to the previous financial fair play (FFP) rulings, with football earnings – similar to break-even results – allowed to show an increased "deviation" from the previously permitted €30million over three years to €60m over the same time period. That is to aid the balance sheets of clubs, ensure the fair value of transactions and to reduce debts, UEFA said.
UEFA's FFP chief Philippe Rasmussen said in a news conference there was an additional €10million allowance in this area "for clubs that are in good financial health".
Ceferin said on Thursday: "UEFA's first financial regulations, introduced in 2010, served its primary purpose. They helped pull European football finances back from the brink and revolutionised how European football clubs are run.
"However, the evolution of the football industry, alongside the inevitable financial effects of the pandemic, has shown the need for wholesale reform and new financial sustainability regulations.
"UEFA has worked together with its stakeholders across European football to develop these new measures to help the clubs to address these new challenges.
"These regulations will help us protect the game and prepare it for any potential future shock while encouraging rational investments and building a more sustainable future for the game."
Coaches including Jose Mourinho, Fabio Capello, Zinedine Zidane, Carlo Ancelotti, Gareth Southgate and Fabio Capello have joined the 24-man UEFA football board, along with superstar former players Paolo Maldini, Luis Figo, Gareth Bale, Rio Ferdinand, Michael Laudrup, Philipp Lahm and Robbie Keane.
There is one non-European on the board, with Inter's Argentine vice-president Javier Zanetti joining a throng that also includes former Germany team-mates Rudi Voller and Jurgen Klinsmann, plus Netherlands boss Ronald Koeman, Rafael Benitez, Patrick Vieira and Eric Abidal.
The noticeably all-male board will hold its first meeting at UEFA's European House of Football headquarters on Monday.
European football's governing body said the group will "give an institutional yet independent voice of experience and expertise on fundamental football-related topics".
UEFA president Aleksander Ceferin said: "UEFA is delighted to see that the very ones who have shaped the game's history with their talents and philosophy through decades are gathered again around our common goal – to protect the game of football and its essential values. As we always say: football first!"
Ceferin is campaigning for clarity on football's handball rules, having recently described the law as "really obscure".
"No one understands it any more," Ceferin said. "So we really need a conversation here, finding solutions and clarifying some issues."
He said that would be an issue for the football board to look at, and it was confirmed on Thursday as being on the agenda for the meeting, along with discussions about the video assistant referee system, player behaviour and medical issues.
UEFA said its technical director and chief of football Zvonimir Boban would chair Monday's meeting, although he is not a member of the new board.
UEFA football board members: Jose Mourinho (Portugal), Carlo Ancelotti (Italy), Zinedine Zidane (France), Paolo Maldini (Italy), Fabio Capello (Italy), Javier Zanetti (Argentina), Luis Figo (Portugal), Philipp Lahm (Germany), Ronald Koeman (Netherlands), Gareth Southgate (England), Rio Ferdinand (England), Michael Laudrup (Denmark), Rafael Benitez (Spain), Roberto Martinez (Spain)
