UEFA, the Asian Football Confederation and CONCACAF have taken the extraordinary step of jointly accusing FIFA president Gianni Infantino of "deception," publishing an open letter on Monday that amounts to the sharpest and most coordinated challenge to his authority since he took charge of world football's governing body a decade ago, ONE reported.

The letter was signed by UEFA president Aleksander Čeferin, AFC president Salman bin Ibrahim Al Khalifa and CONCACAF president Victor Montagliani, along with the three confederations' general secretaries. Between them, UEFA, the AFC and CONCACAF represent the overwhelming majority of the world's national football associations and clubs.

At the heart of the dispute is a now-scrapped FIFA plan, reportedly floated in late July under the name FIFA Forward Enterprise, to sell an interest of roughly 20 percent in a new company that would commercialize World Cup and other major tournament rights, in a deal said to be worth in the region of $4.2 billion to private investors.

The confederations' letter calls the episode a "profound failure of judgment" and a "fundamental breach of trust" with the football institutions FIFA is meant to serve. In its most pointed passage, it states: "When trust is broken through deception, when an individual places himself above the collective that entrusted him with authority, that duty has been abandoned."

Rather than accept an internal FIFA review of how the plan was drawn up and nearly pushed through, the three confederations are demanding a fully independent investigation carried out by outside parties, with no role for FIFA's own administration or staff.

The letter also raises pointed questions about a leadership meeting held in Morocco during the affair, noting that only FIFA management figures were present and that no elected FIFA Council members or representatives of member associations were invited — a detail the confederations frame as symptomatic of a wider breakdown in consultation.

FIFA abandoned the World Cup rights sale at the end of July after the plan drew fierce internal opposition, but Monday's letter shows the confederations are not satisfied that the retreat settles the matter. They want to know how the proposal got as far as it did without their knowledge.

The pressure on Infantino has been building for weeks. UEFA has separately confirmed it served FIFA with a legal "preservation" letter, a formal step that keeps open the option of further legal action over the collapsed deal.

"Football's strength has always been in its unity, and we call on leaders to serve the game instead of trying to control it," the confederations wrote, in a line that reads as a direct rebuke of Infantino's leadership style after nearly ten years in the FIFA presidency.

It is an unprecedented alignment of continental power against a sitting FIFA president, and one that leaves Infantino facing simultaneous pressure from Europe, Asia and North and Central America over how — and for whose benefit — football's most valuable commercial asset, the World Cup, is run.
