Last Sunday night was as close to sporting royalty Australians can get.
The chance to watch two of modern sport's most dominant and likeable personalities, if only from the comfort of the loungeroom, duke it out over five sets at Melbourne Park for maybe the last time, was something truly special.
Just like Roger Federer said, it was probably one occasion when we all would have been happy to see the final result finish in a draw.
The Swiss maestro and Rafael Nadal are that special. Two athletes who will leave a lasting legacy.
Five days on, there is an event so far removed from what transpired at Rod Laver Arena that it will barely be a blip of the global sporting radar - even if the promoters have seen fit to bring in the voice synonymous with boxing around the world, Michael "let's get ready to rumble" Buffer.
Still, Anthony Mundine vs. Danny Green II will be compulsive viewing in Australia. Why? F.O.M.O - or the "Fear of Missing Out".
The acronym probably hadn't even been coined by some smashed-avocado eating millennial when Mundine and Green first stepped into the ring more than 10 years ago.
That night in Sydney, and around the country, fans tuned in with the hope of seeing either a Mundine victory or the former NRL star lying flat on his back in the centre of the ring. It turned out to be the former.
For while Danny Green isn't short on fans himself - he clearly won the 'Applause-O-Metre' at Thursday's weigh-in at Adelaide Oval - there will again be many Australians who will tune in for nothing more than the hope that Mundine will be knocked out.
Proudly Indigenous, Mundine has polarised opinion like few other people in Australia. The former St George Illawarra five-eighth has never sugar-coated his thoughts on racism nor the plight of his people. His comments after the September 11 attacks in New York City in 2001 generated a massive public outcry.
While the general public would usually have little interest in a fight of this nature, rusted-on boxing fans are more often than not in the same boat nowadays given the majority of high-profile bouts today.
Even the much-anticipated showdown between Floyd Mayweather Jnr and Manny Pacquiao was a disappointment. Sure Mayweather fought a skilful fight, dancing around the ring, frustrating his Filipino opponent with sharp footwork and counter jabs.
But there was a lack of physicality the pugilistic arts should provide. It's one of the reasons behind the huge surge in popularity of the UFC and Mixed Martial Arts; fight fans want to see brutality and the only place they seem to get it nowadays is inside the Octagon.
Friday night's fight might well prove a throwback to boxing's golden years. But even if it doesn't, fans will have tuned in either because they want to see Mundine achieve the "clarity" he seeks with a second win over Green in a heavier weight class or because they want to see Green flatten "The Man" with a right hook.
Some will hate themselves for the decision, longing for the misspent hour or so and $20 blown on a few beers. Few will savour the rounds as they did the sets in Melbourne last Sunday.
But that unshakeable thought that something "big" might happen, whatever camp you sit it, means there will be huge interest in the culmination of a massive week for Australian sport.
So while you can thank Federer and Nadal, Mundine v Green II should rate more than just a minor mention, too.
