Xu has five-gold goal

World champion Xu Jiayu, who as a rookie lined up behind bigger names for the photo shoot ahead of the Incheon Asian Games four years ago, has a much higher profile at the Jakarta Asiad, which opens on Aug 18.

Xu was runner-up at the 2016 Rio Olympic Games and claimed victory at the 2017 FINA World Championships in the men's 100m backstroke.

"I expect to better my personal best and break the world record in the 100m here in Jakarta. I also hope I can win as many gold medals as possible - I want five," said Xu, who will compete in the 50m, 100m and 200m backstroke and two medley relays.
