Australian Jelena Dokic withdrew from mixed doubles in preparation for her fourth-round clash with Russian Alisa Kleybanova in the Australian Open.
Though Dokic has never played 19-year-old Kleybanova, the players are somewhat familiar, having practised together in Sydney and Brisbane before teaming up again in Melbourne last week.
Kleybanova, who upset fifth seed Ana Ivanovic on Friday to match her best grand slam result, said she, Dokic and their coaches had become close, and expected the pair to make each other move during the centre court match.
"She's a very nice person. We've been talking through this week, and also my coach and the coach of Jelena, they become very good friends in Melbourne," she said.
"So I'm looking forward to having a good match against her, because I just have to go out there and believe that I can win every match her and just try to play my best tennis."
