Finally we have the dream match-up all tennis fans have been waiting for - Justine Henin v Serena Williams in a Grand Slam singles final.
It seems incredible that the two finest players of the decade just completed have never met before on the ultimate stage despite having collected a staggering 18 major titles between them.
And when Henin retired from the sport in May 2008 it appeared as though the ultimate clash of contrasting styles would never eventuate for tennis fans.
But now after Henin's amazing comeback, the first major final of the new decade - the 2010 Australian Open - will be played between the muscular, powerful American and the petite and graceful Henin.
And just as Muhammad Ali and Joe Frazier were the ultimate match-up in boxing because of their contrasting styles - the boxer versus the brawler - the same equally applies for Williams and Henin when it comes to tennis.
It has often been said that tennis is boxing without the gloves given the individual nature of both sports in which the aim of both is to blast the opponent into submission as soon as possible.
And in so many ways a Henin-Williams match-up is the tennis equivalent of the legendary trio of Ali-Frazier fights which captivated sports fans the world over in the 1970's.
For Ali substitute Henin - minus the bragging of course - and for Frazier substitute Williams.
Henin, like Ali, might lack the knockout punch to be able to blast bigger opponents out of the contest but with her one-handed backhand and graceful on-court movement is so ascetically pleasing on the eye just as the self-proclaimed "Greatest" was in his prime.
Williams on the other hand might lack subtlety in her game like Frazier but again just like 'Smokin Joe', Williams is all power and all heart and simply doesn't know when to quit.
While the pair has never met in a Grand Slam decider, they have met on 13 occasions with Williams holding a narrow 7-6 advantage with their last clash being a straight sets win for Williams in Miami in 2008.
But just as the 'Thrilla in Manila' was the ultimate decider when it came to Ali and Frazier's three epic showdowns in the 70's - so too will Saturday night's Australian Open final go a long way towards splitting the two greatest female tennis players of the 21st century so far.
With 11 major titles Williams stands ahead of Henin and unlike the little Belgian has won all four Grand Slam titles with Henin still yet to conquer Wimbledon.
But six of Williams' Grand Slam titles have come in finals against her sister Venus, which have been underwhelming in the eyes of so many tennis fans and have lacked the passion and contest you would expect of major finals.
Henin, in contrast, has had no such luxury and all of seven of her Grand Slam wins have come in what could be described politely as more genuine finals although that is not to suggest in any way that the all-Williams finals have not been matches in which both sisters have been trying their utmost to win.
Four of Henin's majors have also been at the toughest slam of them all - the gruelling French Open - which Williams has only claimed once.
However Williams has by far the more dominant record at Melbourne Park
