John Millman will be out to prove his giant-killing win over Roger Federer was no fluke as he prepares for his maiden Grand Slam quarter-final appearance.
World No.55 Millman laid to waste Federer's 40-from-40 record against non-top 50 opponents at Flushing Meadows with the jawdropping win on Tuesday (AEST).
All eyes will again be on the Brisbane-born 29-year-old as Millman attempts to add another scalp in the form of 13-time Grand Slam winner Novak Djokovic.
It won't be easy. If anything, it'll be harder. Federer was lethargic against Millman, while Djokovic is arguably the form player on tour at the moment.

Regardless, considering how Millman swept past the 20-time Slam winner, anything will be possible at Arthur Ashe Stadium when the match gets underway on Thursday morning (AEST).
Federer hadn't dropped a set, let alone a bead of sweat, en route to the Millman clash, but left the fourth round in dire straits and sweating like an overweight kid at gym class.
Djokovic, though, is building into momentum of the kind he used to go all the way at Wimbledon in July.
Back in London, the Serb's straight sets victories over Tennys Sandgren and Horacio Zeballos were followed by tougher assignments against Kyle Edmund, Karen Khachanov and Kei Nishikori.
However, it was the extraordinary five-set epic against Rafael Nadal in the semi-final that stirred Djokovic towards his fourth All England crown, which he grabbed with a cruisy win over Kevin Anderson in the final.
At Flushing Meadows, it has been much of the same - tough matches against Márton Fucsovics and Sandgren were punctuated by dominant wins over Richard Gasquet and João Sousa.

WHY MILLMAN'S DAD MISSED THE FEDERER MATCH: "I never saw any of it"
If Nadal, Juan Martin Del Potro and Kei Nishikori are feeling the burn after their exhausting quarter-final matches, then a cruisy win over Millman could set Djokovic up nicely for consecutive Grand Slam wins, and his first at Flushing Meadows since 2015.
However, a fearless Millman remained confident after his win over Federer, saying it would be a "disservice to who I am if I go out there and don't have that belief" against Djokovic.
"Again, it might sound a bit boring but I’ve got to control my side of the court," Millman said.
"I’ve got to be really tight with my unforced errors, take my chances and take it to him a little bit.
"Anything that drops short, I’ve got to try to take advantage of it.
"I’m under no illusions that I’m going to have to have one of my very best days to get the job done."
