Hong Kong badminton coach He Yiming wants Yip Pui-yin to believe in herself and prove she still belongs with the best.
The former Asian Games silver and bronze medallist kicks off her 2013 campaign in tomorrow's US$1 million Korea Open in Seoul, the richest of the 12 Super Series events.
"Her condition is fine and she is injury-free," said He, who put his charges through a tough winter training camp.
"She should be ready for the challenge again. But still her major problem is not with her skills or her form. She simply lacks the confidence to prove she is one of the best in the world.
"The problem has existed for a while and she needs to solve it on her own. It's difficult to help from the outside."
Yip was eliminated in the opening rounds in nine of the 11 Super Series tournaments she contested last year.
The only time she showed a glimpse of her quality was at the London Olympic Games, where she upset two seeded players to reach the quarter-finals.
"She must believe she can do it, just like she did at the Olympic Games," He said.
Yip, now ranked No 21 in the world compared to a career high of eight, will meet mainland young gun Li Han in the first round in Seoul. Chan Tsz-ka takes on a qualifier.
In the men' singles, seventh seed Hu Yun will also meet a qualifier, but Wong Wing-ki faces a tough task against sixth-seeded Nguyen Tien Minh of Vietnam.
"Hu has been getting better and better over the past couple of months and hopefully he can give another good performance," He said.
