Chinese women's judo team coach Wu Weifeng said on Wednesday that her players were fully prepared to meet their Japanese rivals in the Doha Asian Games.

Wu said she read the reports about the withdrawal of Japanese Olympic gold medallist Maki Tsukada from the Asian Games and her successor was Mai Tateyama.

Tsukada, winner of the over 78-kilogram title in the 2004 Athens Olympic Games, withdrew from the Doha Asian Games over a calf injury during a training session in Japan.

"Tsukada's withdrawal is unexpected for us, but we are prepared for such things," Wu said after a training session in Qatar Sports Club, adding that she knew something about 20-year-old Tateyama.

China's judo star Tong Wen, who is expected to meet Tateyama, is in "good shape", Wu said.

Japanese team officials clamored that Japan would sweep all women's judo gold medals in the upcoming Asian Games.

"The Japanese women's judo team boosts several very good players, and Japanese officials used to make such comments (of sweeping all gold medals)," Wu said.

"Gold medals belong to winners in the matches, and the results are not decided by them," Wu said.
