Supremo says Qatar finals could be moved.
It has been a talking point ever since Qatar was announced as having won the bid to host the competition over whether it is practical to host a football tournament during a Middle Eastern summer.
Blatter has now admitted that perhaps it isn’t and that we are now likely to see a change in the scheduling for the event.
Speaking from Qatar ahead of the Asian Cup, he said: "I expect it will be held in the winter.
"We have time to look at this question, it is still 11 years away but we must decide the most adequate period for a successful World Cup, which means January or the end of the year.
"Do not forget there is still 11 years to go and although we have the basic conditions of their bid for a June and July World Cup, the FIFA executive committee is entitled to change anything that was in the bid."
Qatar won the right to host the 2022 World Cup ahead of rival bids from the United States, Australia, South Korea and Japan.
