“I’m quite confident. I’m now ranked second in the world, so I will be the No 2 seed going into the Paris Paralympics,” Chan said. “This will be my last Paralympics, and also my last international tournament.

“I hope that I will get a better result because, in the last Paralympics in Tokyo, I won bronze. So I want to change the colour of the medal. I’m looking forward to it.”

Chan has been representing Hong Kong in international competitions since 2010, two years after he lost his leg in a car accident.

A badminton singles specialist, Chan has won one silver and six world championship bronze medals, as well as bronze and silver in the Asian Para Games.

“So many people were asking if I would be a coach [after I retire], but I’m the only wheelchair badminton player in Hong Kong, so after I retire, there will be no one, so I can’t be a coach,” he said.

“I will still focus on giving training or coaching to people with special needs or physical disabilities.”

Chan said there was a lack of wheelchair badminton athletes in Hong Kong because of the “very tough demands” the sport has.

“Not all athletes with a physical disability are suitable for the game,” he said. “Also, I think in Hong Kong, we are mainly focused on sports for technique, for tactics, but not really physically demanding sports.

“That’s why not many people come into my sport, even though I’m here and I’m having quite good results. I wish that one day there will be another Daniel Chan coming up.”

One athlete who said he would not be stepping away from his sport for a long time was boccia player Leung Yuk-wing.

Leung has competed in every Paralympics since 2004, picking up three golds, two silvers and a bronze. Boccia is a precision ball sport played by wheelchair users and is similar to bowls.

“This won’t be my last Paralympics, I will be here for at least two, three or even four more,” the 39-year-old said. “Age isn’t much of an issue in my sport, so I hope I can continue for a long time.”

Leung, ranked world No 4, will compete in the individual BC4 and the mixed pairs BC4.

In Tokyo, he won bronze in the individual event and silver in the mixed pairs with Vivian Lau Wai-yan and unused teammate Raymond Wong Kwan-hang.

This year, Leung will play alongside Asia’s No 1 female player, Cheung Yuen.

“We have been working together for about a year, and I’m confident that we have good chemistry, it’s good to see progress and I’m confident we will do well,” Leung said.

“The goal is gold, that is very clear. It’s been a while since Hong Kong has won mixed double gold, so this is our aim.”
