"Profit-driven" projects like the European Super League threaten the existing structure and mission of sport, according to International Olympic Committee (IOC) president Thomas Bach.

Bach appeared at the UEFA Congress in Montreux, Switzerland on Tuesday.

The furore caused by 12 of Europe's leading clubs announcing a breakaway competition that would see them leave existing structures in place under UEFA and FIFA continues to cause intense debate.

Bach warned that self-interest and commercialism would come at a huge cost for European sport.

He insisted such an approach was not what was needed as society rebuilds as it emerges from the coronavirus pandemic.

"We have to realise that this European sport model is under threat today," Bach said. 

"In fact, the very existence of the values, solidarity and volunteer-based model is under threat. 

"It is challenged by a purely profit-driven approach that ignores the intrinsic values the social mission of sport and the real needs of the post-coronavirus world. 

"It is under threat because the social mission of sports organisations is losing ground to the purely profit-oriented goals of commercial sport providers and investors. 

"If everything is only looked at from a business perspective. If only the economic rules are applied to measure the impact of sport on society then the social mission of sport is lost.

"In this polarising environment narrow self-interest and egotism have been gaining ground over solidarity, shared values and common rules. 

"We can only address the challenges of the post-coronavirus world in solidarity. This means for us solidarity within sports organisations and solidarity among sports organisations."

At the same conference, FIFA president Gianni Infantino condemned the European Super League.

Infantino warned clubs involved they "cannot be half in or half out" and must fully commit to the breakaway competition.

Former Real Madrid president Ramon Calderon was frustrated to see 12 elite clubs plotting a European Super League at a time when football needs "solidarity and unity".

Madrid were among a dozen teams to announce their involvement in a new breakaway competition on Sunday.

The lucrative tournament would be a rival to the Champions League, but the 12 "founding clubs" would compete every year and could not be demoted.

While reigning European champions Bayern Munich and Ligue 1 giants Paris Saint-Germain have not yet signed up, which Calderon says is "really important", this threat to the sport's structure comes as clubs attempt to recover from the coronavirus pandemic.

For this reason, Calderon - the main man at Madrid between 2006 and 2009 - finds the plans particularly painful.

"The first thought that came to my mind when I read the news about this announcement was that perhaps it came at the worst moment in football history," he told Stats Perform News.

"Many clubs are suffering, are struggling financially because of the pandemic. I think football needs more than ever solidarity and unity to overcome this problem.

"So, I think it's bad news for football and I hope that common sense comes back to everyone and they manage to sort out this situation in the best way possible."

COVID-19 has made money particularly tight at Madrid, where they are also renovating the Santiago Bernabeu.

"Maybe this is the money we need to sort out all the problems we are having and we are facing in the next few years," Calderon suggested.

But UEFA's threat to deny Super League players the opportunity to represent their countries at international level could yet derail the proposals, according to the ex-Madrid chief.

Calderon said: "If that really happens, if they fulfil their threats, I'm sure the clubs will reconsider going on with the project.

"It's impossible if UEFA and FIFA ban clubs and players in the way they have [said] in their statements. I find it difficult that they'd go on with the project."

But that is not the only problem for Calderon, who believes Super League clubs would quickly find their existence tedious playing the same opponents without additional leagues and cup competitions.

"I think they already have the opportunity to see those teams playing against our team," he said.

"But also in our country, and I think in other countries it's the same, fans want to travel to other stadiums, they want to win [against] their neighbours. There's a rivalry always between the clubs from the same country.

"And also there's something interesting nowadays that any club can win three or four competitions, or at least, compete to win them.

"With the Super League, there'll only be one champion. The others won't get a trophy. That's another thing that I don't think they've taken into account.

"Now Barcelona is out of the Champions League, but they won the [Copa del Rey]. So, if they play in the Super League, they'll only be able to win one title.

"That's another interesting thing for fans, for players and for clubs."

UEFA president Aleksander Ceferin thanked the club officials who have stood by Champions League reform proposals on Tuesday.

Ceferin was speaking at the UEFA Congress the day after criticising those involved in the breakaway European Super League in emotional comments.

Plans for a new rival competition, widely deemed anti-competitive, were announced at the weekend by 12 clubs including Real Madrid, Barcelona and Manchester United.

They face a backlash from many throughout the world of football, including UEFA and president Ceferin.

But on Tuesday, Ceferin preferred to focus on those who have not at this stage signed up for the Super League as UEFA tries to push through its own new competition format.

Reigning European champions Bayern Munich have released a statement in opposition to the Super League, while last season's beaten Champions League finalists Paris Saint-Germain - chasing their first title again in this year's competition - are also not involved.

Bayern chief executive Karl-Heinz Rummenigge will replace Agnelli as one of the European Club Association's (ECA) representatives on the UEFA executive committee.

And Ceferin picked out Nasser Al-Khelaifi, the PSG president present at the event in Switzerland, for praise.

"Thank you from the bottom of my heart to Nasser," Ceferin said in his opening statement. "You have shown that you are a great man and that you respect football and its values.

"I also thank Karl-Heinz Rummenigge, a fantastic president for the ECA, and [Lyon's] Jean-Michel Aulas, who came here today.

"But also Jose [Castro] from Sevilla, with whom I had a very reassuring discussion yesterday evening and with whom we share the same vision of football. Thank you."

United chief executive Ed Woodward and Juventus chairman Andrea Agnelli had been the subject of particularly scathing comments from Ceferin on Monday.

He spoke of "snakes" and said: "I have seen many things in my life. I was a criminal lawyer. I have never seen people like that."

FIFA president Gianni Infantino condemned the European Super League as he warned clubs involved they "cannot be half in or half out" and must fully commit to the breakaway competition.

Twelve elite clubs announced on Sunday their plans to launch a tournament to rival the Champions League in which they would be assured of qualification.

Real Madrid, Barcelona and Manchester United, among others, would compete in the Super League every season without risk of demotion.

The news has prompted a strong reaction throughout the football world, with governing bodies, rivals clubs, players, coaches and fans critical of the idea and its anti-competitive format.

An initial FIFA statement on Sunday read: "FIFA can only express its disapproval to a 'closed European breakaway league' outside of the international football structures."

Infantino, FIFA president since 2016, had not subsequently discussed the Super League in public until Tuesday's UEFA Congress, however.

But he made clear in Montreux, Switzerland, that the clubs involved could not continue in their domestic leagues, as proposed, while bans from international football for players at those clubs have been threatened.

"At FIFA, we can only strongly disapprove the creation of the Super League, which is a closed shop, which is a breakaway from the current institutions, from the leagues, from the associations, from UEFA, and from FIFA," Infantino said.

"There is a lot to throw away for maybe a short-term financial gain of some. People need to think very carefully. They need to reflect and they need to assume responsibility.

"If some elect to go their own way, then they must live with the consequences of their choice. They are responsible for their choice.

"Concretely, this means either you are in or you are out. You cannot be half in or half out."

Everton have accused the six Premier League clubs who have signed up to the European Super League of "betraying" football supporters.

Plans for a breakaway league were announced on Sunday, with Manchester City, Manchester United, Liverpool, Chelsea, Arsenal and Tottenham among the 12 teams confirmed to have signed up.

The news was met with a wave of criticism from across the spectrum, including fans, governing bodies, players, ex-professionals and other clubs.

And on Tuesday the Toffees made clear their feelings on the matter in a scathing statement which attacked the involvement of their fellow English top-flight outfits.

"Everton is saddened and disappointed to see proposals of a breakaway league pushed forward by six clubs," read a statement from the club's board of directors.

"Six clubs acting entirely in their own interests.

"Six clubs tarnishing the reputation of our league and the game.

"Six clubs choosing to disrespect every other club with whom they sit around the Premier League table.

"Six clubs taking for granted and even betraying the majority of football supporters across our country and beyond."

The Merseyside club were particularly critical of the timing of the move, coming amid a global pandemic which has threatened the very existence of some clubs.

"At this time of national and international crisis – and a defining period for our game – clubs should be working together collaboratively with the ideals of our game and its supporters uppermost," the statement continued.

"Instead, these clubs have been secretly conspiring to break away from a football pyramid that has served them so well.

"And in that Pyramid Everton salutes EVERY club, be it Leicester City, Accrington Stanley, Gillingham, Lincoln City, Morecambe, Southend United, Notts County and the rest who have, with their very being, enriched the lives of their supporters throughout the game's history. And vice versa.

"The self-proclaimed Super Six appear intent on disenfranchising supporters across the game – including their own – by putting the very structure that underpins the game we love under threat."

Since the plans were made public, the dissenting voices have come from every corner, with UEFA threatening sanctions, fans protesting and even players and managers speaking out against them.

It is a reaction that Everton say must be taken on board by those leading the charge for a European Super League.

"The backlash is understandable and deserved – and has to be listened to," the club's board said.

"This preposterous arrogance is not wanted anywhere in football outside of the clubs that have drafted this plan.

"On behalf of everyone associated with Everton, we respectfully ask that the proposals are immediately withdrawn and that the private meetings and subversive practises that have brought our beautiful game to possibly its lowest ever position in terms of trust end now.

"Finally we would ask the owners, chairmen, and Board members of the six clubs to remember the privileged position they hold – not only as custodians of their clubs but also custodians of the game. The responsibility they carry should be taken seriously.

"We urge them all to consider what they wish their legacy to be."

If you are a football fan there is simply no escaping the controversy caused by the announcement 12 teams have signed up to form a breakaway European Super League.

Talk of such a competition is nothing new, rumours have been swirling for years, but the furore caused has still been widespread with pundits, players and fans alike united in their disapproval.

UEFA and the major European governing bodies and leagues have vowed to do all they can to kill the proposals and huge sanctions have been threatened if the teams go ahead with the league.

But part of the debate has also centred around the credentials of some of the teams who have been invited to participate, with six from the Premier League, three from LaLiga and three from Serie A agreeing to join. Below we have reviewed each of the 12 clubs involved.

THE 'BIG SIX' FROM THE PREMIER LEAGUE

Arsenal

Arsenal's place on the list comes with the club having failed to qualify for the Champions League since the 2016-17 season, the penultimate year of Arsene Wenger's long reign. The Gunners appear unlikely to make a return via the domestic route this season, as they sit well adrift of the top four in the Premier League. However, they are still in the Europa League, with a semi-final tie against Spanish side Villarreal – coached by former Arsenal boss Unai Emery, no less – to come.

Chelsea

The outlook for Chelsea changed dramatically in 2003, when Roman Abramovich became the new owner. Prior to the Russian's arrival, the Blues had one the top-flight title just once. They have been crowned Premier League champions five times since, however, and also enjoyed Champions League success in 2012. In overcoming Porto across two legs, they have reached the semi-finals of the competition this term for the first time since 2014.

Liverpool 

The Reds have a storied history, but there has been success in recent seasons under the guidance of Jurgen Klopp. No British club has won Europe's premier club competition more times than Liverpool, while the 2019-20 Premier League title triumph finally ended a 30-year wait to get back on their perch at home. However, they only featured in the Champions League once between the 2009-10 and 2017-18 campaigns, while their hopes of repeating their success of 2019 since lifting the trophy in Madrid have resulted in exits to Spanish opponents who also involved in the Super League. 

Founded: June 1892

Trophies won:
First Division/Premier League: 19 times

Manchester City

The Premier League champions in waiting are on course to claim a third title with Pep Guardiola at the helm. However, City slipped down to the third tier of the English football pyramid as recently as 1998, while only became one of the powerhouses of the domestic game following the arrival of a new owner in Sheikh Mansour. They first appeared in the Champions League in 2011-12 and are yet to get beyond the semi-final stage, meaning the Cup Winners' Cup success in 1970 remains the club's only European trophy.

Founded: April 1894

Manchester United

United were the dominant force in the Premier League era under Alex Ferguson, winning the title 13 times to overtake Liverpool's record tally. However, since their legendary manager departed, the Red Devils have not managed to add to their overall tally as 20-time top-flight champions. There was FA Cup success under Louis van Gaal - who was then sacked - and an EFL-Europa League double during Jose Mourinho's time in charge at Old Trafford. In the Champions League, United have only gone as far as the last eight since losing the 2011 final to a Lionel Messi-inspired Barcelona.

Tottenham

Now searching for a new manager following the dismissal of Jose Mourinho less than 24 hours after confirming their Super League involvement, Spurs' best-ever finish in a Premier League season came in 2016-17 when second behind champions Chelsea. There was a Champions League final appearance in 2019 too, though they missed out on glory when losing 1-0 to Liverpool. Indeed, Tottenham have not secured silverware since the League Cup triumph in 2008, while the most recent of their two top-flight league titles was way back in 1960-61.

THE REMAINING CLUBS INVOLVED

Atletico Madrid

A huge club in their own right, of that there is no doubt. But the last of Atleti's LaLiga title wins came in 2014, and that was only their second since 1977. Three times runners-up for Europe's greatest continental prize but as yet there has been no Champions League triumph for Atletico Madrid. While Diego Simeone has overseen a great period at Atleti, and the club has muscled into the fight with their more illustrious Clasico rivals, it should certainly be no shoo-in that Atleti deserve an automatic spot at this table.

Founded: April 1903

Barcelona

Another LaLiga heavyweight, boasting the talents of Lionel Messi of course, that would certainly not be out of place in a Super League, both in terms of history and trophies won. Barcelona's well-documented financial issues off the pitch may also offer a further explanation for the desire for a mind-boggling windfall. While Barca were beaten to LaLiga by Clasico rivals Madrid last term, they have already collected silverware this time around in the form of the Copa del Rey. Champions League success has not arrived since 2015 but Barca's credentials stand up to scrutiny.

Founded: March 1899

Inter

The Milan giants are a club rich in history, who have scaled the heights in European football.  But also another who have struggled to reach such past glories until this term – with Antonio Conte's side appearing primed to win a first Serie A title since 2010, the year Jose Mourinho oversaw a famous treble also comprising the Coppa Italia and Champions League. While some would dispute Inter's place in a Super League, the signs are the Nerazzurri are on the way back to consistently challenging among the elite.

Juventus

The Old Lady of Italian football. With 36 Serie A titles to their name, Juventus are the most successful club in the history of the Italian top flight. While the Bianconeri have not won the Champions League since 1996, they have been runners-up in 2015 and 2017 and no one can doubt the grandeur of this historic club. The past decade in Italy has been dominated by Juventus who have won nine titles in a row, but their quest for 10 has hit a bump as a side spearheaded by the evergreen Cristiano Ronaldo sits fourth in the maiden campaign of Andrea Pirlo.

Founded: November 1897

Milan

Once of the most revered and loved teams across the globe, the Rossoneri have fallen on hard times in recent years. Only Madrid can boast more than Milan's seven European/Champions League victories, while many of the all-time greats have donned the famous red and black jersey. But you have to go back to 2007 for the last time Milan were crowned champions of Europe, while 10 years have past since they lifted the Serie A title. Indeed, they have not even played in the Champions League since the 2013-14 campaign – albeit Stefano Pioli's men appeared destined to return to the competition this term.

Founded: 1899

Real Madrid

While some of the teams in this controversial process may raise a few eyebrows, there is little doubt a club with the prestige of Real Madrid would not be involved. Record winners of the European Cup/Champions League on 13 occasions (the last of which coming as recently as 2018, the third in succession under Zinedine Zidane), and 34 times winners of LaLiga (including last season) there is little doubt Los Blancos are an established part of the European elite. This term, they are into the semi-finals of the Champions League and sit second in a tight race for the top flight title in Spain.

UEFA president Aleksander Ceferin has branded the planned European Super League as a "disgraceful, self-serving proposal" fuelled by greed, as well as confirming players from the 12 breakaway clubs involved will be banned from international football.

The 'big six' from the Premier League have collaborated with Atletico Madrid, Barcelona, Inter, Juventus, Milan and Real Madrid to reveal plans for a new midweek club competition.

Those founder members would automatically qualify each season no matter where they finished in their respective domestic leagues.

Speaking during a conference call to reveal "dynamic" changes to UEFA's current European club tournaments, Ceferin made clear how results on the pitch should always decide who participates, rather than a "closed shop run by a greedy few".

"We began this project to modernise the competitions in 2019 judged by the principle it should be: an exercise in inclusive leadership," Ceferin told the media.

"At the start of the process, we were driven by a desire to help all UEFA club competitions into something even better than the spectacles we know today. With the unanimous support of the European Club Association (ECA), we consulted widely across the game.

"Teams will always qualify and compete in our competitions on merit, not a closed shop run by a greedy, select few. That was our decision from the beginning.

"Any club, any fans should still have the dream of participating in the Champions League based on their results on the pitch."

The European Super League plan has come in for widespread criticism and Ceferin did not hold back in his own assessment, as well making clear the ramifications it will have for players outside of club football.

"I must address the extraordinary situation that has developed on the eve of this announcement," he continued.

"I cannot stress more strongly at this moment that UEFA and the footballing world stand united against the disgraceful, self-serving proposal in the past 24 hours from a select few clubs in Europe that are fuelled purely by greed above all else.

"Not only is the football world united, but society is also united, governments are united. It's part of our culture – we are all united against this nonsense of a project.

"We have the English FA, Spanish Federation, Italian Federation, Premier League, LaLiga, Serie A, and also FIFA and all our 55 member associations unanimous in opposition to this cynical plan that are completely against what football should be.

"Our game has become the greatest sport in the world based on open competition, integrity and sporting merit. We cannot allow, and we will not allow that to change, ever. Never.

"As previously announced by FIFA and the six confederations, the players that play in the teams that might play in the closed league, will be banned from playing in the World Cup and the Euros. They will not be able to represent their national teams in any matches."

UEFA announced plans for Champions League expansion that will see an increase to 36 teams as the present format -  whereby there are eight pools of four – will be scrapped.

Instead, each team will play 10 group games before advancing to a last-16 knockout format. The changes are due to be introduced for the 2024-25 season.

"Whoever thinks the Super League and UEFA are all about money is not right. Super League is only about money, money of the dozen – I don't want to call them the dirty dozen," Ceferin said. 

"UEFA is about developing football, about financing what should be financed, that our football and our culture survives. Some people do not understand it.

"The reforms preserve the value of the domestic game by retaining the principle that domestic performance should be the key to qualification – this should, and will not, ever change.

"The European game is the greatest success story of the modern sport, and there's a reason why – because of its pyramid, it's long history. We are constantly adapting the European competition to ensure it is more and more interesting, more and more modern, but the principles cannot change.

"Solidarity is something that cannot change, but for some people solidarity doesn't exist, unity doesn't exist. The only thing that exists is their pockets."

Thomas Tuchel refused to condemn the formation of a European Super League and is adamant he trusts Chelsea to "make the right decisions" as he called for all parties to remain calm.

Chelsea were confirmed as one of 12 founder clubs of a new semi-closed competition on Sunday, with The Super League – as it has been dubbed – attracting widespread criticism.

UEFA, in a statement co-signed by the national associations of England, Spain, Italy and those countries' respective top leagues, vowed to ban players and teams from other competitions if they become involved in the Super League.

It remains to be seen if UEFA and the domestic leagues have the power to stop the Super League, but Tuchel cut a relaxed figure amid the hysteria as he addressed the media on Monday ahead of Tuesday's meeting with Brighton and Hove Albion.

He told reporters: "I've known since yesterday, but I am here to be in the hardest competitions, it's why I came here, to play the toughest competitions in Europe.

"As you know, I don't get into the subjects around us. I was hoping to talk about Man City and Brighton but it's not the case.

"I am part of this club and I trust this club to make the right decisions. I think it's too early to judge everything and it's not my part.

"On my badge it says that everyone has to play their role. My role is to coach, be focused, and we've another game tomorrow.

"There are a lot of comments, arguments and opinions out there and I don't want to get involved in it because I don't know the details. I've known the general details since yesterday."

Regarding the opinions of players and staff, Tuchel added: "If I had a clear opinion right now I wouldn't mention it - it's too early to judge it and there are way too many opinions out there.

"I trust this club and my job is very clear. I am maybe not the right person to ask this of. I understand why there are many emotional reactions out there, but I don't know enough about it.

"The players were not involved in the decision making, I wasn't involved. Maybe it's a good thing to step back and not give our opinions about this. It's between the clubs and it's important to fight for the goals we still have this season."

UEFA has made its position on the Super League crystal clear regarding the potential exclusions of teams.

Whether it is able to enforce such decisions is another matter, but Tuchel hopes all parties can calm down as they look to find solutions.

Asked if he was worried about potential punishment impacting Chelsea's season, Tuchel said: "There was not too much time to get worried. Clearly, I hope not.

"Everyone wishes for a calm atmosphere and situation to have full focus. Do we have it, maybe not but it's clearly our choice if we get influenced, read too much about it, get lost in sports politics.

"We are involved in this club to play our role and make our challenge happen at the highest level. This is what I am here for. Nobody expects anything else from me, except for maybe you guys in the next few days.

"Nothing will change between me and the team. Sometimes in the middle of the storm is the calmest. Let's hope it is like this and I don't want to enter in this as it may sound like an excuse."

Europe's top leagues and UEFA have vowed to do everything in their power to block a so-called European Super League and urged others to boycott what they describe as a "cynical project founded on the self-interest of a few clubs".

In an emphatic response to media reports, UEFA together with the English Football Association (the FA), Premier League, the Royal Spanish Football Federation (RFEF), LaLiga, the Italian Football Federation (FIGC) and Serie A have joined forces in attempt to quell the Super League.

They reiterated a pledge to ban teams from other competitions if they take part in the Super League, while FIFA's threat of barring players from the World Cup was also alluded to.

French and German clubs were also thanked for refusing to sign up to the tournament, meaning neither of last season's Champions League finalists – Bayern Munich and Paris Saint-Germain – are set to be involved.

The statement read: "UEFA, the English Football Association and the Premier League, the Royal Spanish Football Federation (RFEF) and LaLiga, and the Italian Football Federation (FIGC) and Lega Serie A have learned that a few English, Spanish and Italian clubs may be planning to announce their creation of a closed, so-called Super League.

"If this were to happen, we wish to reiterate that we – UEFA, the English FA, RFEF, FIGC, the Premier League, LaLiga, Lega Serie A, but also FIFA and all our member associations - will remain united in our efforts to stop this cynical project, a project that is founded on the self-interest of a few clubs at a time when society needs solidarity more than ever.

"We will consider all measures available to us, at all levels, both judicial and sporting in order to prevent this happening. Football is based on open competitions and sporting merit; it cannot be any other way.

"As previously announced by FIFA and the six federations, 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.

"We thank those clubs in other countries, especially the French and German clubs, who have refused to sign up to this. We call on all lovers of football, supporters and politicians, to join us in fighting against such a project if it were to be announced. This persistent self-interest of a few has been going on for too long. Enough is enough."

Bayern Munich chairman Karl-Heinz Rummenigge does not want to see UEFA's Financial Fair Play (FFP) model scrapped and has called for tougher sanctions for clubs that break the rules.

FFP regulations, approved by UEFA in 2010 to prevent clubs that qualify for its competitions from spending beyond their means, appear set for significant changes due to the ongoing impact of the coronavirus pandemic.

The break-even requirement, which means clubs must balance their spending with their revenues and restricts the accumulation of debt, has been declared "purposeless" by UEFA in the context of the revenue crisis caused by COVID-19.

Changes to those specific regulations could well be on the horizon but, though Rummenigge sees the merit in such adjustments, he is firmly against talk of FFP being scrapped altogether.

He told The Athletic of the break-even rule: "Right now, you're allowed to lose €30million (£25.8m) over three years.

"You can't even buy a player for that kind of money, so it's worth looking into it if that can be sensibly adjusted."

However, on FFP as a whole, Rummenigge added: "Things were spiralling out of control, with many clubs losing money in the past.

"FFP has led to a more rational approach, by forcing clubs to budget sensibly and it has made football profitable as a result.

"We can't get to the point where only clubs owned by billionaires can compete."

Rummenigge and the Bayern hierarchy have long been vocal about their commitment to a self-sustainable business model, and he is keen to see FFP changed so that it features harsher penalties for clubs that do not live within their means and breach regulations.

"The current FFP doesn't quite get it right, because the punishments don't work," said Rummenigge. "They're not well defined enough, it's all a grey area.

"Clubs who violate the rules in the future must face much more severe sanctions. We need to really get it right this time. Smart people are looking at it."

Gianni Infantino says FIFA must be open to revolutionising the international calendar, after Arsene Wenger proposed radical changes.

Speaking on beIN SPORTS this week, former Arsenal manager Wenger claimed more focus had to be put on FIFA's flagship competitions, including the World Cup.

The Frenchman is currently serving as FIFA's chief of global football development.

Wenger put forward a plan to host major tournaments such as the World Cup and European Championship every two years, to give more players the opportunity to play at these events during their prime years.

Such changes would mean major alterations to the calendar, but Infantino insists FIFA will rule nothing out, and decisions could be taken within the next 12 months.

"We need to be open to everyone, to everything, to every proposal, every idea," said the FIFA president.

"Arsene Wenger is not only a successful and brilliant manager, he is a professor of football but besides that we have, of course, our bodies and we will debate and discuss the calendar, starting now, because we need to come to a decision in the next few months, the sooner the better, by the end of the year or in the course of next year, for everyone to be able to plan."

The international schedule is not the only item up for debate, with Infantino also interested in a possible merger of North America's leading leagues – Major League Soccer (MLS) and Liga MX.

MLS commissioner Don Garber commented in December that a merger was "a long way away", while FIFA has previously ruled out leagues spread across regions or continents, rather than individual countries.

However, Infantino seemingly sees things differently, as he stressed the need for other areas of the globe to challenge the quality on show in Europe.

"I think the potential in the United States and Mexico is enormous, each country by itself," he said.

"But of course if you could bring those two together that would be incredible and that could quite well be the best league in the world.

"Any discussion about organising such a competition, of course respecting the rules of member associations and FIFA and with the agreement of all stakeholders, any discussion in that respect is interesting and we see that in a positive light.

"Of course if we want club teams to be at the highest level around the world and not just in Europe, we need to have new ideas.

"We see the potential in North America, the economic potential and the potential in footballing terms. I trust them to take the best decisions in that regard."

Ajax goalkeeper Andre Onana has been suspended for 12 months by UEFA due to a doping violation, the Eredivisie club have confirmed.

Ajax and Onana will appeal to the Court of Arbitration for Sport (CAS) to overturn the ban, imposed after an out-of-competition test in October 2020 found the substance Furosemide in the player's urine.

The club said the test result was due to Onana, 24, mistakenly taking Lasimac – a drug prescribed to his wife – when he felt unwell.

UEFA therefore accepted Onana "had no intention of cheating", an Ajax statement read.

It added: "However, UEFA believes, on the basis of the applicable anti-doping rules, that an athlete has a duty at all times to ensure that no banned substances enter the body."

The suspension is effective from Friday and applies to "all football activities, both national and international".

Ajax managing director Edwin van der Sar said: "We explicitly renounce performance-enhancing drugs, we obviously stand for a clean sport.

"This is a terrible setback, for Andre himself but certainly also for us as a club. Andre is a top goalkeeper, who has proven his worth for Ajax for years and is very popular with the fans.

"We had hoped for a conditional suspension or for a suspension much shorter than these 12 months, because it was arguably not intended to strengthen his body and thus improve his performance."

Cameroon international Onana has been a key man for Ajax since his debut in 2016-17, playing his part in runs to the Europa League final and Champions League semi-finals.

His absence is the latest blow to Ajax, who earlier confirmed they would be unable to correct the administrative error that saw Sebastian Haller left out of their Europa League squad.

Haller, signed from West Ham for a club-record €22.5million last month, was not included in Ajax's initial list for European competition for the second half of the season.

Coach Erik ten Haag described the mistake as "an administrative error with major consequences" and "an incredible setback" for the player, although he confirmed Ajax would be addressing the matter with UEFA.

However, a further club statement has now confirmed UEFA sent "a final message" to say Haller could not be added to the group.

Haller has scored two goals in his first seven games for Ajax in all competitions.

UEFA is committed to its plan of hosting Euro 2020 across 12 host cities, despite the ongoing coronavirus pandemic.

Euro 2020 was due to take place last year, with 12 nations having been selected to host matches in celebration of the competition's 60th anniversary.

However, the COVID-19 crisis resulted in UEFA taking the decision last March to push the tournament back to 2021.

Although Europe is still struggling to deal with the pandemic, with many nations under lockdown rules and travel severely restricted in a bid to limit the spread of the virus, UEFA has reaffirmed its intention for the competition to take place later this year.

In a statement released on Wednesday, UEFA also said it is retaining hope that the 12 venues will be able to accommodate some fans, despite club competitions continuing behind closed doors.

The statement read: "UEFA repeated its commitment to holding the Euro across the 12 cities according to the timetable that has already been published.

"All parties recognise the need for flexibility around decisions to be made on the arrangements for the tournament, in order to reflect the different challenges and circumstances that cities find themselves in. 

"As a result of that and the fast-changing nature of the situation around the pandemic, the deadline for the submission of plans to accommodate fans inside the stadiums has been moved to early April."

In limited numbers, spectators had been allowed into venues in certain European nations – including Germany, England and France – in 2020, though those schemes were ended as infection rates increased again.

"UEFA is committed to holding Euro 2020 in the 12 cities originally planned," UEFA president Aleksander Ceferin said.

"The Euro is the flagship competition for national team football in Europe and is a vital source of funding for grassroots and wider football development. 

"I am optimistic that things are highly likely to be very different with regard to the virus as we move closer to the tournament and it is important that we give the host cities and governments as much time as we can to formulate an accurate picture of what will be possible come June and July. 

"Fans are such a big part of what makes football special and that is true of the Euro as much as it is of any game. We must allow ourselves the maximum space to allow their return to the stadiums."

London, Rome, Glasgow, Bilbao, Dublin, Copenhagen, Amsterdam, Baku, Budapest, Bucharest, Saint Petersburg and Munich are the designated host cities for the finals.

Each city will host three group games, and one match in either the round of 16 or quarter-finals, with the semi-finals and final to be played at Wembley Stadium.

UEFA president Aleksander Ceferin could push for the delayed Euro 2020 finals to be staged in just one country, according to Karl-Heinz Rummenigge.

Any such move would cause a drastic redrawing of plans for the tournament just months out from its start, with 12 cities across Europe preparing to stage games.

The logistical implications would be enormous, with the need to find suitable team bases a major issue, while finding agreement on which country might serve as sole host may not be straightforward.

UEFA took similar steps last season to ensure the Champions League and Europa League campaigns could finish without further delay, but a month-long European Championship is on a different scale to those club competitions.

Yet the COVID-19 crisis could mean there are obstacles to staging the event as originally planned, and that could trigger contingency measures.

Quoted by German publication TZ, Bayern Munich chief executive Rummenigge said: "You shouldn't forget that the idea of ​​this special hosting of the tournament came about when corona did not yet exist.

"At the time, it was an initiative of the EU Commission that wanted to have football shown all over Europe. But I know that the UEFA president Aleksander Ceferin – who is incredibly careful with corona – is thinking about whether it wouldn't make more sense in times of corona to play the tournament in just one country."

UEFA's expansion of the tournament to a 24-team event, starting from Euro 2016, means it is now close in scale to a World Cup, and the opening match is due to take place on June 11, with Italy and Turkey set to play in Rome.

Shifting the quarter-final stages of last season's club competitions to Lisbon and Germany meant they were able to be completed, with barely two months between decisions being taken and the games going ahead.

This is due to be the first time UEFA has held a European Championship in such a spread of venues. Ceferin referred to the Euros in December as "a tournament bridging the entire continent".

UEFA also said in November it intended to proceed with the tournament in its original format, albeit accepting that could change depending on circumstances.

It has since said decisions on how many supporters, if any, will be able to attend games, are set to be taken in March.

The semi-finals and final are scheduled to be held at Wembley Stadium in London, with other games in Baku, Amsterdam, Rome, Bilbao, Bucharest, Budapest, Copenhagen, Dublin, Glasgow, Munich and Saint Petersburg.

FIFA has warned that any player competing in a European Super League would become ineligible to take part in World Cups, European Championships or the Champions League.

Amid speculation that the biggest clubs from the Premier League, LaLiga, Serie A, Bundesliga and Ligue 1 are keen on forming a breakaway competition, football's world governing body has taken a strong stance against such ideas.

A joint statement from FIFA and the six continental federations read: "In light of recent media speculation about the creation of a closed European 'Super League' by some European clubs, FIFA and the six confederations (AFC, CAF, CONCACAF, CONMEBOL, OFC and UEFA) once again would like to reiterate and strongly emphasise that such a competition would not be recognised by either FIFA or the respective confederation.

"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.

"As per the FIFA and confederation 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.

"In this respect, the confederations recognise the 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.

"The universal principles of sporting merit, solidarity, promotion and relegation, and subsidiarity are the foundation of the football pyramid that ensures football's global success and are, as such, enshrined in the FIFA and confederation statutes.

"Football has a long and successful history thanks to these principles. Participation in global and continental competitions should always be won on the pitch."

It was reported in October that FIFA were hoping to create a closed 18-team tournament that would be dubbed the 'European Premier League'.

However, FIFA president Gianni Infantino said he was "not interested" in the idea and felt the existing Club World Cup had greater potential.

Prior to his resignation as Barcelona president, Josep Maria Bartomeu revealed at a news conference that he had accepted a proposal for the club to join the proposed European Super League.
