Novak Djokovic v Lorenzo Musetti live: Australian Open live score updates with history on the line in quarter-final

Wow! Djokovic finds the outside of the line and Musetti goes wide on the angled volley, but Djokovic concedes the point as he admits the ball brushed the outside of his racket!

That’s extraordinary sportsmanship, at a big moment, because it would have been 40-15 to Djokovic. Instead, he is taken into deuce, and then set point as Djokovic nets!

Musetti floats a backhand slice long and Djokovic is offered some encouragement ahead of a crucial 30-30 point.

After a let, Musetti responds with an ace out wide – clutch. Musetti will be grateful to see another error from Djokovic, the forehand sprayed wide.

You know Djokovic is struggling when he is putting relatively simple drop shots into the net under no pressure.

He does, though, hold serve by landing a forehand winner and ace, keeping Musetti in sight.

Stunning, again, from Musetti, with a chipped drop shot finding the line and the spin taking it away from the chasing Djokovic.

But in this game things can all change in a moment and Djokovic gets a look at break point as Musetti balloons his forehand long!

Djokovic looked to be in control of the point in a 17-shot rally, but Djokovic lands his forehand into the net.

Musetti keeps his cool to control a series of overheads. Djokovic nets after being stretched out wide.

This has been exhibition stuff from Musetti, who is keeping the single-backhander alive with a beautiful winner down the line. Djokovic holds.

Musetti holds and Djokovic is now looking to be in some trouble. He makes another error on the forehand, blasting wide, before Musetti seals it with an ace.

Djokovic strikes the top of the net and doesn’t get the bounce as he is dragged into deuce.

And the errors just keep piling up! Two more from Djokovic, including a forehand long on break point, and Musetti breaks ahead once more.

That’s five unforced errors in the second set for Djokovic already, 23 overall!

What’s the Italian for complete opposite? After a golden game of winners, Musetti is broken to love with a string of errors. Djokovic puts the pressure on behind the return and breaks straight back.

Musetti comes flying out of the blocks with back-to-back-to-back winners! The first is a forehand return down the line, then Musetti produces a stunning crosscourt forehand, that dips behind Djokovic!

Musetti then makes it three in a row with a flying forehand, bringing three break points.

And Musetti takes it with a lob! Djokovic is stranded at the net and the Italian finds the touch.

That’s a stunning game from the 23-year-old. Magical. He moves a set and a break up.

A sign of nerves from Musetti as he nudges a volley wide from the net on the opening point?

Perhaps, but Musetti doesn’t show then as the Italian finds two big serves. Djokovic goes long on the return and Musetti has two set points.

And Musetti takes it with a scorching forehand down the line, striking it on the rise! Sublime.
