FIFA cancelled 2021 U-20 and U-17 World Cups

As a result of the Covid-19 pandemic, the Bureau of the FIFA Council has decided to cancel the 2021 editions of the men’s FIFA U-20 World Cup and FIFA U-17 World Cup, and to appoint Indonesia and Peru respectively, who were due to host the tournaments in 2021, as the hosts of the 2023 editions.
The Covid-19 pandemic continues to present challenges for the hosting of international sporting events and to have a restrictive effect on international travel. FIFA has therefore regularly consulted the relevant stakeholders, including the host member associations as well as the confederations involved in both tournaments originally scheduled to take place in 2021. In doing so, it became clear that the global situation has failed to normalise to a sufficient level to address the challenges associated with hosting both tournaments, including the feasibility of the relevant qualification pathways.
