Former FIFA president Sepp Blatter says the North American bid to host the 2026 World Cup now seems "afraid" of losing to Morocco.

A change in strategy this week gave the leaders of the U.S, Canada and Mexico federations equal status in a bid that has been heavily favoured to win the hosting rights on June 13 in Moscow.

The reshuffle reduced the role of previous bid chairman Sunil Gulati, the most senior American in FIFA who served on the world governing body's executive committee under Blatter.

Multiple high-ranking executives within FIFA and the continental confederations told ESPN last month that some estimates have Morocco not just threatening the North American bid but actually beating it, and Blatter said the changes was proof that the bid is uncertain.

"They give the impression that they are not any longer very sure that they will win, that's my impression," Blatter said on Thursday. "But I don't know why they are afraid."

Last month, Blatter wrote on Twitter that Morocco was the "logical host" of the 2026 tournament. FIFA preferred single-nation World Cup hosts under Blatter's leadership.

Still, Blatter declined to fully endorse Morocco's ability to host a 48-team tournament alone. The 2026 edition will have the 16 extra teams wanted by Blatter successor Gianni Infantino, who supports multi-nation bids.

"I don't know if the Moroccans are able to organize a World Cup of 48," Blatter told invited reporters at a briefing in Zurich related to his own legal issues.

Both bids will formally submit plans next week. A FIFA-appointed panel will then evaluate the candidates and publicly score them for potential organizational and commercial risks.

Two days ahead of his 82nd birthday, Blatter said he was "a happy man." He is still seeking to challenge a six-year ban from football for unethical conduct, a punishment that followed Swiss federal prosecutors opening criminal proceedings against him in September 2015. He has yet to be charged.

The Swiss official has long blamed an executive committee vote in December 2010 that picked Russia and Qatar as future World Cup hosts for sparking American and Swiss federal investigations of FIFA officials that ultimately forced him from office.

Though Blatter says he voted for the United States bid that lost to Qatar for the 2022 hosting rights, he said that doesn't mean the country deserves to get the 2026 edition.

"I was in favour of the U.S. for 2022. To say now they must have 2026..." he said, pausing to add: "History will show if it's right or wrong."

Blatter acknowledged he once thought the 2026 contest was "a decision that was taken" in favour of North America.

Last May, the three co-hosts pushed FIFA to give them preferential status before Morocco joined the contest by an August deadline with little bid structure in place.

Blatter said the U.S. team's failure to qualify for this year's World Cup -- which led to Gulati not seeking re-election as U.S. federation president -- complicated the leadership issue. The bid calls for the United States to host 60 of 80 games in 2026, with Canada and Mexico hosting 10 each.

"They have put all the three together in order to show that it is a combined organisation. They should have taken the decision at that time [of the World Cup exit]," Blatter said. "The USA is big and the decisions are not always easy to understand."
