New Delhi:Sania Mirza's decision not to play in any forthcoming tournament in India notwithstanding, the tennis ace has done enough for the country, believes former world number one Serena Williams.
"She plays or not, she has done a lot for her country," Serena said here today.
"She takes in what she believes in," said the American, who won her first singles title of the season at the Bangalore Open yesterday.
Serena, who was here to launch a new range of HP designer Laptops, reiterated that Sania was definitely a top-10 material but she needed to be consistent in her game.
"There is a great pressure (when one plays for country). She has already done a lot and she can reach top-10, but she has to be consistent for that," Serena said.
The chirpy American, however, was stumped when one scribe asked her about star batsman Sachin Tendulkar.
"I am from the United States and there we do not play cricket. The word 'cricket' is the only thing I know about this game," she said, after pondering over the surprise question.
On being asked about her on-court rivalry with elder sister Venus, Serena said, "I think of winning. She is great champion and has great experience."
