German star Andrea Petkovic is tipping Serena Williams to quickly bounce back to her best ahead of next month's Australian Open after a disappointing finish to the year.
After a three-month absence, Williams will return to the WTA tour next week at the Brisbane International where she'll be seeded fourth behind Sam Stosur, Petkovic and Italy's Francesca Schiavone.
Despite US Open champion Stosur being keen to kick off the new year with a title at her home tournament and defending Australian Open champion Kim Clijsters looking to continue an unbeaten run in Brisbane, Petkovic believes Williams is the woman to beat.
The American sits outside the top 10 at No12 in the world rankings due to an injury-interrupted year which ended abruptly after Stosur upset her in the US Open final in September.
But the 10th-ranked Petkovic, who idolised Williams as a child, fully expects the 13-times grand slam winner to continue her habit of returning from a lengthy break in great form.
