New swim coach aims to upstage Olympic squad at worlds

China's newly appointed national swimming coach thinks his wards can one-up the squad's Olympic achievements when the World Championships roll round in July.

"The situation now is even better than is was during the Olympics in August," said Yao Zhengjie. "We are aiming to win at least one gold medal (at the worlds).

"We have an advantage in the women's relay as well as in the men's freestyle, where Zhang Lin has showed great potential. From my point of view, there are five to seven events we have a chance of winning."
