Netizens rally to wish Li Na the best

While there is no official confirmation of Li Na's pending retirement, the Chinese tennis ace received an overwhelming number of good wishes from fans across the Internet - around 13 million.

Since Thursday morning, several Chinese websites cited insiders as saying that Li, 32, will announce her retirement on Friday because of a serious knee injury.

Other reports said that Li's management company, IMG, will hold a news conference to announce her decision on Sunday and that a farewell ceremony will be held during the China Open, scheduled for Sept 27 to Oct 5 in Beijing.
