Infantino has come under increasing pressure over his aborted Fifa Forward Enterprise (FFE) proposal.
That would have involved selling stakes in the World Cup and other competitions to private investors, and it sparked a major backlash.
The Welsh governing body was among the first national associations to withdraw backing for Infantino’s bid to continue his leadership of Fifa.
Infantino will stand for election for a fourth time in March 2027, with his opponents having until 18 November to find an alternative candidate.
Mooney reiterated the FAW would not be endorsing Infantino’s candidature.
“With the Fifa president, you’re looking for a moral guardian of the game,” Mooney told the BBC Radio Wales Phone In.
“You’re not looking for somebody to sell off parts of the game.
“The World Cup does not need private equity. They have billions and billions of dollars in reserve.
“Give us the money. Let us build the pitches. You’ve got loads of reserves. Let’s have it as soon as possible.
“There was a summit in Miami before as the World Cup kicked off, a meeting of all 211 federations.
“I stood up at that meeting and said, look, I mean, the revenue for Qatar was around eight billion.
“The revenue for this World Cup in Canada, USA and Mexico is 16 billion. Therefore, it’s 100% increase in revenue, give us 100% growth.”
