Some European football clubs are already up in arms over the idea of a change, which they say would force leagues and competitions to overhaul their calendars to accommodate.
In addition, FIFA, which derives millions from the sale of broadcast rights, marketing and sponsorship, could run into trouble with its core source of revenue.
Ticket sales represent a small percentage of FIFA's income. Sixty percent to 65 percent of its revenue comes from the sale of broadcast rights. Marketing and sponsorships generate most of the rest.

A date change could upset U.S. networks in particular, as it might conflict with the NFL calendar. Between 2014 and 2022, CBS, NBC, FOX and ESPN are expected to pay a total of more than $39 billion for the rights to the NFL season.
Add to that concerns that a new calendar slot might force the World Cup to compete for airtime with the 2022 Winter Olympics.
Broadcasters aren't the only ones FIFA needs to worry about. Other countries that bid for the 2022 World Cup, such as the U.S. and Australia, will demand compensation for the bidding costs incurred during the tender process.

Under the structure of that tender, the 2022 World Cup was to be a summer event. And while FIFA officials say bidding documents hold a provision for a date change, it's by no means certain their case is water-tight.
While Qatar already expects to spend up to $162 billion on infrastructure for the World Cup, there's no indication that Qatar would be willing to divert that money to compensate broadcasters and sponsors for a date change.
And that could leave FIFA to foot the bill.
