Length of contract: 3 years | Annualised value: US$1.7 million | Overall value: US$5.1m

Jelena Jankovic, the world's number one women's tennis player going into 2009, has agreed a new sponsorship deal with Chinese clothing and footwear company Anta after being dropped by Reebok.

Anta, which aims to compete with Nike and Adidas in China, have guaranteed the Serb US$5.1 million over the course of the deal, and described it as "one of the biggest deals in world tennis".

"The recent success of the Beijing Olympics firmly established China's reputation as a world power in sport," Jankovic said.

"I feel very honored to be forming a partnership with the leading Chinese sports brand, Anta. I am delighted with the JJ range of products we have developed and I look forward to working with Anta to promote the development of tennis and the ANTA brand worldwide."

There appeared to be initial problems, though, when Jankovic complained about the heat of the floor at the Australian Open.

"My feet were burning," she said.

"The soles of my shoes got so hot. During the changeovers I was putting my feet on ice, trying to cool them down."

She quickly added: "I like my shoes."
