Victoria Azarenka takes on last year's semi-finalist Na Li in the fourth round of the 2011 Australian Open.
Li surprised a lot of people last year by reaching the semi-finals, beating Caroline Wozniacki and Venus Williams along the way. Twelve months later, the Chinese star is the player in form having won the Medibank International last week, beating Kim Clijsters in the final.
Clijsters afterwards said that Li definitely has the game to be a Grand Slam champion and with the Australian Open more open than ever, she has a great chance if her form holds over the next week.
She's yet to drop a set so far, destroying Barbora Zahlavova Strycova 6-2, 6-1 in the last round. Azarenka has looked equally imposing and no one has come close to taking a set off her so far.
Azarenka's potential has been talked about for a while but she has yet to really deliver in the majors. Quarter-final showings in Melbourne, Paris and London are as good as it's got so far.
Li leads 2-1 on the head-to-head but Azarenka won their only match last year, 6-3, 6-3 in Montreal.
