FIFA President Gianni Infantino described the bid process for the 2026 World Cup as "fair, objective and transparent" after the global soccer body announced it had received bid books from two candidates on Monday.
FIFA, which is due to choose the hosts at its annual congress in Moscow in June, said in a statement it had received one bid from Morocco and a joint bid from the United States, Canada and Mexico.
The two bids will be evaluated by a task force which will visit all the potential host nations, FIFA added.
"I challenge anyone to point out an organisation that conducts a bidding process as fair, objective and transparent as the one that FIFA is carrying out for the 2026 FIFA World Cup," Infantino said in the statement.
"FIFA has been heavily criticised for how it conducted the selection of hosts in the past; it was our obligation to learn from this and leave no room for any doubt or subjectivity," he added.
"This is why the rules of this process... include the highest standards in terms of ethical conduct, participation and commitment to sustainability and human rights."
