THE Badminton Association celebrated Hong Kong's bronze medal effort at the Commonwealth Games last night - but there was no rejoicing for newly-appointed national coach Chan Chi-choi. Chan, who officially takes over as the Hong Kong Sports Institute's head badminton coach from Diana Lo Leung Bik-luen on New Year's Day, saw four of his leading women players quit the sport. Commonwealth Games representatives Chung Hoi-yuk, Chan Oi-ni, Wong Chun-fan and Cheng Yin-sat have decided to retire, leaving coach Chan with only two senior women internationals - Ngan Fai and Tung Chau-man - in his care. 'I knew this would happen after the Asian Games because the girls have expressed their concern about the future and want to get a job before they are too old to start a new career,' said Chan. 'It is a major blow to see them leave at the same time, especially because the next generation of players are still in their mid-teens and it will take years before they can reach the elite level.' The nine-strong squad who won the mixed team bronze at the Commonwealth Games in Victoria three months ago received a $100,000 bonus. from Hong Kong Badminton Association president Tong Yan-kai last night.
