"For FIFA, if there's the will to change something for the international calendar for one year, it's possible to do, because if there's a will, there's also a solution," the head of world football's governing body told reporters.
"But for now, there are the pros and cons but it is premature to make any decisions on what may happen but all I am saying is that winter is not only January and February, winter is also the end of the year."
The IOC is especially sensitive to a winter World Cup because it could hamper that year's winter Olympics. It has called on FIFA to discuss the matter with Olympic officials once it has decided on the dates of the tournament.
"It would be sensible once a decision is envisaged by FIFA to sit around the table to see it is not harmful for either of the two parties," IOC president Jacques Rogge said earlier this month.
