On Wednesday night, Infantino had "full support" of FIFA's management board despite being forced to abandon his plan to sell stakes in a company to run the World Cup to private investors.
The Swiss' plan was rejected by three continental confederations before it was withdrawn and led to UEFA threatening to boycott FIFA competitions until it was scrapped - a position which European football's governing body doubled down on on Thursday.

A UEFA statement said: "UEFA's associations were very clear about the conditions attached to the non-participation in FIFA competitions.
"First, the proposals to sell off the major competitions had to be withdrawn, and secondly, assurances have to be made that such attempts to disfigure the game in this way will never be made again.
"These conditions have not been met. In addition, UEFA made it abundantly clear in its statement on Saturday that it has lost confidence in Gianni Infantino's presidency. That position holds.
"Yesterday's (Wednesday) announcement that some people employed by the FIFA President (and whose careers depend on his favour) agree with him changes nothing."
