Elaine Thompson-Herah is the best sprinter in women's history according to former 400m hurdles champion Edwin Moses.

The Jamaican sprinter became the first woman in history to complete the double-double by defending her Olympic 100 and 200 metre titles in Tokyo before adding her third gold of the Games in the women's 4x100m relay on Friday.

Thompson-Herah, 29, set a new national record with her earlier 200m success and recorded the second-fastest time in the history of the event.

Those achievements led Moses, a former American track star and two-time Olympic gold medallist, to the conclusion that Thompson-Herah is in a class of her own.

"She’s the best women's sprinter in history," Moses exclusively told Stats Perform. "She's proved that over and over.

"She came through at the right time, I think people were concerned about her and even when she ran against Dina Asher-Smith and didn't win, people were concerned but she was obviously in that final phase of training and she didn't want to show her cards. She did an outstanding job."

Thompson-Herah, fresh from her earlier 100m exploits, fell just 0.19 seconds short of Florence Griffith-Joyner's long-standing 200m world record that was set in 1988.

However, Moses explained there is a possibility that the five-time Olympic champion could complete the seemingly impossible and break Griffith-Joyner's records.

"It's possible. Obviously it's going to depend on the track," Moses continued. "If it's not the Tokyo track we don't know what she's capable of doing.

"She ran very, very fast there and those kinds of times are going to be much harder to run on normal tracks and aren't that Mondotrack that they had in Tokyo."
