Blatter reiterated that any request to change the timing of the event to cooler months would have to come from the organisers themselves.
He could not predict whether such a request would lead to a legal challenge from any of the countries who lost out to Qatar in the vote held in December 2010.
"We are not losing control with the World Cup, or 2022," he told a news conference at FIFA headquarters.
"Concerning the 2022 World Cup, discussions started at the time when the decision was taken and then people have realised that when playing summer will be difficult because it is very hot.
"But the basic principles of the award of the World Cup were very clear and have not changed in the meantime.
"They are still the same, FIFA's World Cup is a competition with 32 teams and 64 matches, and has to be played in June and July.
"This has never been put into question by the organisers, who have been given the responsibility.
"If there is a move it must come from Qatar, it is not relevant to the FIFA executive committee which stands by the decision taken in December 2010."
However, FIFA said in a statement on Thursday that Blatter had said: "Any request for change must come from Qatar. But they have not made this request yet, because they know that if they do so, the other bidders could say 'ah, there is a change'."
"I have put a question mark and that's all but I'm not a prophet to say what will happen," he said. "Let us be where we are and let us work on the World Cup 2014, there is enough to do for that competition, and then 2018 and then 2022.
