US President Donald Trump has publicly defended Fifa president Gianni Infantino, warning that removing him from his post would be a "terrible mistake."

Trump's intervention came after Uefa, Concacaf, and the Asian Football Confederation released a joint open letter accusing Infantino of breaking trust "through deception" in connection with his now-abandoned Fifa Forward Enterprise (FFE) proposal.

What was the FFE proposal?

The FFE scheme would have established a new company to oversee the commercial and ticketing rights for all Fifa competitions — including World Cups — with 21 percent of that company sold to a private investment firm.

The proposal drew sharp criticism from three of football's most powerful confederations before Infantino withdrew it.

Trump's strong backing for Infantino

Writing on social media, Trump expressed unequivocal support for the embattled Fifa president.

"Fifa would be making a terrible mistake if, for any reason, they even considered replacing president Gianni Infantino. He is fantastic, having just presided over the most successful World Cup, by four times, ever presented. If he is gone, it will never be as successful or profitable again."

Trump appeared to be referencing the FIFA World Cup 2026, which was co-hosted by the United States, Canada, and Mexico this summer. Spain claimed the title, defeating Argentina in the final.
