The football world appears to have been split down the middle by the issue, with the confederations of Africa, South American and Oceania having backed Infantino.
But even within confederations, there is disagreement and it makes it very difficult to predict whether Infantino or his opponents have the upper hand in this battle.
In Oceania, which has 11 member associations, New Zealand has said it will not follow the confederation and vote for him.
Mexico, Grenada and St Kitts and Nevis have broken away from the other 32 Concacaf nations to support the Fifa president.
Of the 46 Asian confederations members, so far eight countries have split to champion Infantino’s cause – the United Arab Emirates, Qatar, Sri Lanka, Lebanon, Kuwait, Mongolia, the Philippines and Bhutan.
The Fifa Council, on which there are 36 confederation and national association heads plus Infantino, seems similarly split.
It raises questions about whether Infantino has the political power to govern Fifa, even if he wins an election of the 211 member associations.
The first test of Uefa’s threat is just over three weeks away, when the Fifa Under-20 Women’s World Cup is set to kick off. It is being hosted by Poland and features five other European nations, including England.
