China's talented long jumper Shi Yuhao is hoping for a good result in Tokyo despite struggling to return to his best form since coming back from injury at the beginning of the year.

Shi, 21, said the fact that the Tokyo Olympic Games were pushed back was a blessing in disguise for him as it would give him more time to return to his best.

"It could be a good thing for me because I need more time to adjust. Now I need to focus on my new skills," said the 2018 Asian indoor champion.

Shi was badly injured in 2018's Shanghai Diamond League event where he won a silver medal with a personal best of 8.43 meters. He underwent surgeries on his left foot and spent more than six months in rehabilitation.

Since the injury, he is attempting to switch his take-off leg to his right.

"I am still not used to it. After all I had been taking off with my left leg for a decade," he said.

"My running speed is at 90 percent of my previous best but the level of jumping related indexes is not good enough. I hope I can return to competition as soon as possible," he said.

"Hopefully I will sing the song of victory in Tokyo," he said in a caption of a video clip made by himself.
