Several national associations are frustrated they only learned of the plans when Fifa went public, yet notably, most statements so far have not directly opposed the sell-off idea itself.
Even so, BBC Sport understands many Uefa members are angry about the proposal and are set to meet to decide their response.
On Tuesday, Uefa said Fifa’s plan aims “to use our sport to enrich themselves and their friends”.
Reports suggest European nations could even threaten a World Cup boycott, arguing that a tournament without Europe would greatly diminish its value to Fifa.
However, the likelihood of that actually happening is uncertain.
Europe will be a primary host of the 2030 tournament, with Spain and Portugal staging most matches alongside Morocco, and Spain is pushing hard to secure the final over Morocco.
Next year’s Women’s World Cup in Brazil could be an earlier focal point for action if Uefa chooses to take a bold stand.
Uefa could also try to field a challenger to Infantino in next year’s presidential election, but with only 55 votes, its chances of success are slim.
If Ceferin and other European leaders want to mount the strongest possible resistance, they will need to act quickly and decisively.
For now, Infantino appears as confident and emboldened as ever.
