FIFA will on Thursday hold a summit with all 211 national football federations as it seeks to gather support for controversial plans to stage the World Cup every two years despite vociferous opposition from Europe.Officially the summit, which is being held online, is taking place to discuss the international calendar for both men’s and women’s football beyond 2024 and world football’s governing body insists all scenarios remain open. However, in recent weeks FIFA has been actively pushing the idea of a biennial World Cup, rather than staging the competition every four years. The idea has been floated before, by former FIFA president Sepp Blatter in 1999, and it was brought to life again earlier this year by Arsene Wenger in the ex-Arsenal manager’s current role as FIFA’s Chief of Global Football Development.06 October, 21.45: (2.40) Italy (3.15) Spain (3.40)It is an incendiary topic given all the different interests at stake, between clubs and national teams, domestic leagues and international competitions. There has been a wave of criticism from within European football but also from representatives of domestic leagues the world over, from players and from supporters. Wenger has suggested holding a major international tournament every year, alternating between World Cups and continental events like the European Championship and the Copa America.Space would be created, he claims, by staging all qualifying matches in October, or October and March, rather than spacing them out across the year. Each national federation has one vote in the FIFA Congress, regardless of its size, and the perspective of increased revenues created by more regular World Cups could be enough to seduce many in Africa, Asia or Oceania. However, FIFA and its president Gianni Infantino are not solely relying on them. They recently summoned a host of former players and coaches, so-called “legends” who are paid as ambassadors, to Doha to promote the project.Wenger on football changes: ’I’m ready to take the gamble’Earlier in September world football’s governing body released the results of an online feasibility study involving 15,000 football fans. It claimed 55 percent were in favour of more frequent World Cups than the current four-year cycle. But the battle lines are being drawn, and the opposition to FIFA’s plans is being led by UEFA and Conmebol, the confederations of European and South American football, alongside representatives of leagues around the world and leading European clubs.They have all hit out at the lack of consultation, given the extent to which a World Cup every two years would disrupt their own calendars while forcing clubs to release players for international duty even more often than is already the case. Concerns have been raised about the physical and mental health of players, with global players’ union FIFPro pointing out the “natural physiological limits” of footballers.UEFA president threatens to boycott World Cup if Wenger’s idea goes aheadFIFA’s project “would dilute the value and meaning of club and country competitions” according to the European Club Association (ECA), and “diminish and conflict with women’s and youth football”.Those who oppose the idea are convinced that it is the very rarity of the World Cup which makes it so attractive and that holding it every two years would lead to its value being diluted. Numerous supporters associations across the globe have also underlined the difficulty of following a major international competition every year.Meanwhile, Infantino hopes a decision can be made by the end of this year and he could decide that a simple vote of national federations is enough.08 October, 02.00: (2.10) Uruguay (3.20) Colombia (4.20)However, the ECA has accused FIFA of being in “direct and unilateral breach of certain obligations”, referring to an agreement, the so-called memorandum of understanding, that is currently in place until 2024 and includes “joint approval” on the international calendar.The 247 clubs represented by the ECA have another potential ace up their sleeves too: They are the employers of many of the players involved in major international tournaments and could simply refuse to release them.© Agence France-Presse
