Melbourne: Serena Williams has beaten Maria Sharapova in all of their last nine meetings and plans to pass on key tips to big sister Venus ahead of her Australian Open clash with the Russian on Friday.
Venus is still on the comeback trail from injury and illness and will need all the assistance she can get in her third round match with the world number two. Serena said Thursday she was ready to help.
"It will be a big match. I think Venus obviously has nothing to lose, and she will play great tennis. She will do her best," she said of her sister, who hasn't won a Grand Slam since Wimbledon in 2008.
