Can anyone deny Novak Djokovic a record-extending 10th men's singles title at the Australian Open?
Only two other top-10 seeds remain at the quarter-final stage, with 2022 champion Rafael Nadal and Casper Ruud among those to suffer early exits.
Of those still standing in Melbourne, 21-time Grand Slam champion Djokovic is the only major winner.
Despite being hampered by a hamstring injury, he has lost only one set in his four matches so far as he looks to make up for lost time after missing last year's tournament.
The former world number one, who was deported after his visa was cancelled in 2022, has not lost a match at the Australian Open since 2018.
