Much has changed for Andy Murray since he last played Roberto Bautista Agut at the Australian Open - and much has stayed the same.
Since then he has gained a metal hip, but as he battled to take a five-set victory against Thanasi Kokkinakis in the early hours of Thursday, it was clear his desperate will to win is unchanged.
The 35-year-old, who also needed five sets to beat Matteo Berrettini in the first round, finished playing at 04:00 Melbourne time and was back at Melbourne Park eight hours later to begin his fourth-round preparations.
Now ranked 66th in the world, Murray will face 24th seed Bautista Agut for an Australian Open quarter-final place few would have dared to predict back in 2019.
