Ousting FIFA boss would be 'terrible mistake' - Donald Trump backs Gianni Infantino

US President Donald Trump says it would be a "terrible mistake" if under pressure Fifa president Gianni Infantino was ousted from his position.

Trump's backing followed Uefa, Concacaf and the Asian Football Confederation issuing an open letter accusing Infantino of breaking trust "through deception" with his aborted Fifa Forward Enterprise (FFE) proposal.

FFE would have meant a new company being created to manage commercial and ticketing rights of all Fifa competitions, including World Cups, with 21% sold off to a private investment company.

Trump's comments are the first time he has come out in defence of Infantino since the FFE plans came to light on 28 July.

"Fifa would be making a terrible mistake if, for any reason, they even considered replacing president Gianni Infantino," Trump wrote on social media.

"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."

The 2026 World Cup was co-hosted by the US, Canada and Mexico this summer, with Spain crowned champions after beating Argentina in the final.

When addressing the FFE proposals for the first time on 31 July, Trump said he had not spoken to Infantino about the plans.

Thrive Eternal was expected to lead the proposed investor group for FFE.

Thrive is an American venture capital firm founded by Joshua Kushner - the brother of Trump's son-in-law Jared.
