Infantino is facing the biggest crisis of his decade-long tenure after regional confederations UEFA and CONCACAF declared no confidence in his leadership following the abortive proposal to bring private equity into the World Cup.

He confirmed his intention to stand for a fourth term at next year's Congress in April but the pressure on Infantino may not wait until the election. Wales on Monday became the first soccer federation to formally withdraw support for Infantino, while European body UEFA confirmed it had written to the 56-year-old Swiss to inform him it was weighing legal action against him regarding the proposal.

Opponents can mount a push to depose him with a vote at an Extraordinary Congress (EC) if 20 per cent of Fifa's membership of 211 member associations request one in writing.

An EC would need to be held within three months of a request, providing time for rival candidates to emerge.

UEFA, whose 55 member nations voted to boycott all Fifa tournaments if the stake sale went ahead, alone could trigger an EC with a unanimous vote.

Lawyers for UEFA have informed Fifa that the European body is "actively considering legal action, arbitration, and/or regulatory complaints ... arising out of and in connection with the FFE (Fifa Forward Enterprise) plan proposed by Fifa and all related matters."

The letter dated Friday from the legal firm Dechert in New York was seen Monday by The Associated Press.

The letter named 18 Fifa executives who it said should retain data, documents and electronic messages as potential evidence.

"UEFA puts you on formal notice that any destruction, deletion, alteration, concealment, or loss of relevant materials following receipt of this notice - or following any earlier date on which you were, or reasonably should have been, aware that proceedings were anticipated - may constitute spoliation of evidence," the letter said.

On Saturday, UEFA signaled it wants to end Infantino's decade-long presidency, saying he had lost the confidence of world soccer and that "no option should be off the table."

However, getting a majority of Fifa's membership to vote Infantino out at the EC may not be an easy task.

Despite vast disparities in wealth, soccer development and influence across the footballing world, all 211 nations have an equal vote.

Rather than smoothing things over with established football giants like France, Spain and England, Infantino's best chance of clinging to power may rest with members like Bhutan and Vanuatu -- emerging nations that have never competed at a World Cup and rely overwhelmingly on Fifa to support their football programmes and participate in international events.

Fifa members have been able to claim up to $3 million for soccer development projects over the course of the 2023-26 World Cup cycle, $1 million more than the previous cycle.

The money is small beer for rich nations with professional teams but vital for football's have-nots.

The stake sale was always aimed at the latter members, and many have done well under Infantino's patronage.

Vanuatu influence

Vanuatu are ranked 160th in the world and sixth among the Oceania confederation teams but their football association head Lambert Maltock has a seat at Fifa's highest table as one of eight vice-presidents in the body's Executive Council.

Fifa gave the island nation of about 340,000 people a development grant of $4.15 million to help build a 6,500-seat stadium in the capital Port Vila, which was completed in 2022.

For Vanuatu's first professional player, Brian Kaltak, Infantino's backing has been a huge boost for the country and developing nations generally.

"First of all, he gave a chance for our president to be part of Fifa and then with development projects, he's been trying to grow the game -- not just Vanuatu but all third-world countries," the Perth Glory defender told Reuters on Monday.

"He's opening up more chances for a team like ours, for nations like ours to make it ... It's been a massive help."

Similar funding splashes are common across Asia, Africa, the Caribbean and the Pacific, where Fifa grants have financed training pitches, gyms and soccer programmes that national associations would otherwise struggle to finance.

For critics, however, that same funding model has reinforced a system in which Fifa trades financial power for political influence, making it difficult to build a coalition to unseat an incumbent president.

Any campaign to remove Infantino may ultimately be a numbers game that extends far beyond Europe's traditional elite.

England follows Wales as both withdraw support for Infantino re-election

Wales became the first national federation to formally withdraw its support for Infantino, followed by England.

"The Football Association of Wales hereby confirms its withdrawal of support for the candidature of Mr. Gianni Infantino, for re-election as Fifa President for the 2027-2031 term," the Welsh FA said in a statement.

"The recent failures in good governance, processes, leadership, values, stakeholder management, communications and sound judgement have led us to a position where Mr. Infantino has lost the confidence of the FAW to remain at the helm of world football.

"Failing to put the best interests of football first is a failure we cannot accept."
