So here's a look at five of Serena WIlliams' best matches at the Australian Open.

While Serena Williams was an established star in 2010, Victoria Azarenka was just rising up the ranks. The Belarusian finished the 2009 season ranked inside the top 10 and had won the biggest title of her career by defeating Williams in the 2009 Miami Open final.

At the 2010 Australian Open, the pair met for the third consecutive year. Williams triumphed in 2008 and 2009, and while she would go on to win in 2010 as well, Azarenka put up an impressive fight this time around.

Williams was down a set and trailing 0-4 in the second before staging a remarkable fightback. Azarenka's explosive game had the American on the ropes, but Williams' fighting spirit shone through as she rallied to win 4-6, 7-6(4), 6-2.

#4 - Serena Williams vs Maria Sharapova, 2007 Australian Open final

Serena Williams started the 2007 season ranked No. 95, with injuries plaguing much of her 2006 campaign. Going into the Australian Open that year, she wasn't among the favorites despite her past accomplishments.

But Williams made her way to the final, where she was to face Maria Sharapova. The last time the two met in a Grand Slam final was at Wimbledon in 2004, when the Russian emerged victorious to win her maiden Grand Slam title.

Sharapova was expected to win given her excellent form, but a dominant performance from Williams saw her claim a third Australian Open title. The American was dialed in right from the start, committing just 11 unforced errors to win 6-1, 6-2.

While many had written an obituary about her career, Williams made a statement with her commanding performance and silenced her detractors.

Facing Kim Clijsters for a spot in the final, the American was thoroughly tested. She lost the first set 6-4 but fought her way back into the match to win the next one 6-3. The Belgian raced to a 5-1 lead in the deciding set and held two match points while on serve.

But just when it seemed like all was lost, Williams exerted her will and clawed her way back into the match. The American won six straight games to take the match 4-6, 6-3, 7-5 and reach her fourth consecutive Grand Slam final.

After splitting the first two sets, the deciding one was a tense affair and the two fierce competitors gave it their all. Sharapova got the decisive break and was serving for the match at 5-4. The Russian even had three match points, but was unable to close the match out.
