How does Andy Murray keep managing to leave us all stunned? He's a 35-year-old with a metal hip, for goodness sake.
Even Murray looked like he could not quite believe what he had done, puffing out his cheeks after a thrilling five-set victory over Italian 13th seed Matteo Berrettini at the Australian Open on Tuesday.
He spent almost five hours on court, saving match point at 5-4 in the deciding set before winning the tie-break 10-6.
Some of Murray's fellow players were glued to screens watching the British three-time Grand Slam champion put in a vintage performance that legendary sports stars and mesmerised fans on social media could find only two words for: Andy Murray.
