We can't postpone it again: Olympics official sees 'real problems' in holding Games in 2021

Coates indicated that officials would start deciding in October if and how the pandemic-hit Games could go ahead in July 2021.

Sydney: John Coates, the International Olympic Committee's pointman for Tokyo 2020, on Friday warned that holding the postponed Tokyo Games next year faces "real problems", with even a vaccine unlikely to stave off the threat of the coronavirus.

Coates indicated that officials would start deciding in October if and how the pandemic-hit Games could go ahead in July 2021.

He told a roundtable organised by an Australian media giant that Japanese Prime Minister Shinzo Abe has been clear the Tokyo Olympics could not be delayed a second time.

"We can't postpone it again and we have to assume that there won't be a vaccine or, if there is a vaccine, it won't be sufficient to share around the world," he said.

Without the safety net of a widely available vaccine, there could be enormous challenges in screening tens of thousands of people from all corners of the world, he said.

"We've got real problems because we've got athletes having to come from 206 different nations," said Coates.

"We've got 11,000 athletes coming, 5,000 technical officials and coaches, 20,000 media, we've got 4,000 working on the organising committee there at the moment, there will be 60,000 volunteers coming," he said.

"There's a lot of people."

Coates said if there are signs the pandemic is contained, even if not eradicated, by October, officials will start preparing "the different scenarios by which the sport could take place".
