SAITAMA - Japanese figure skater Mao Asada said Sunday, the day after winning the world title, that she needed more time to decide when to retire from competition. Asada , the runner-up to South Korean star Kim Yu-Na at the 2010 Vancouver Olympics, has kept her fans in suspense by saying she had a "50-50 chance" of continuing to compete after this season. "What I feel is that I need some rest now," the 23-year-old told reporters during an exhibition after the season-closing world figure skating championships in Saitama near Tokyo. "I have struggled for three years as I could not skate the way I wanted and jump the way I wanted," she said. "I had thought about staking my career on the Sochi Olympic season," she added. "I am finally beginning to really get a grip of how I can perform."–AFP
