Djokovic and Muller are in the locker room and the spectators have disappeared. I suppose we could keep live texting throughout the afternoon, just for a laugh, but it wouldn't be particularly funny.

If you missed any of the news and chit-chat from today's play, you can read our well-crafted round-up. There's also plenty on Murray versus Kyrgios, should you want to do some revision on the big match. Bye for now, but join us tomorrow for live text coverage of Murray's quarter-final with Kyrgios.

Here's some head-to-head chat to keep you occupied for about 20 seconds: Sixth seed Murray has met home favourite Kyrgios once on tour, with the Briton winning in straight sets in Toronto last summer.

The pair also locked horns at the International Premier Tennis League (IPTL) exhibition in India two months ago, which Murray won.

As BBC Sport's Piers Newbery says in his preview, 19-year-old Kyrgios is the first Australian man for 10 years to reach the last eight of the Aussie Open and hopes to become the first for 39 years to win the title.

Will the pro-Kyrgios crowd ruffle Murray's feathers? "Obviously the crowd will be right behind him, understandably so," says Murray.

"They're going to watch him play a lot of matches like this over the next 10, 15 years probably, and that's just something that I'll have to deal with in my way."

Dreamy quarter-final line-ups in store for us this week, with the pick of the bunch perhaps Andy Murray's clash with Nick Kyrgios. The pair will meet in the night session match on Rod Laver Arena at 08:15 GMT on Tuesday.

When was the last time Djokovic lost a Grand Slam quarter-final? It was at the French Open in 2009 when, as fourth seed, he lost to Philipp Kohlschreiver in the third round.

Djokovic is through to his 23rd consecutive Grand Slam quarter-final and he will next face Canada's Milos Raonic.

"He's one of the three, four guys of the future generation," says Djokovic of his next opponent. "If you serve as well as he does it gives you a lot of advantage over your opponents so I guess I'm going to have to return well."

"I want to wish happy Australia Day to everybody," says Djokovic, who now has the crowd in the palm of his hands. "He deserves a lot of respect and I was fortunate to serve very well in important moments in the third set and not allow him to capitalise in important moments.

"It's never easy playing against somebody who takes away the time from you. He comes to the net, he slices. He's a great player overall. He was a quality in his serve. I did feel uncomfortable at times, I was slipping a lot."

Djokovic finding his grove, collects three match points, and there's no comeback for Muller from here. The 31-year-old with a tired-looking shot into the net and Djokovic celebrates by closing his eyes and raising his arms in the air.

Djokovic swinging with confidence on the return, drilling a forehand beyond Muller for a 0-30 lead. At 15-30, Djokovic pounces on a feeble Muller backhand volley and Djokovic's reply - a crackerjack of a volley - earns the four-time champion two break points.

Meltdown alert. Djokovic with an angry monologue as his backhand down the line drifts wide. Muller unruffled and, once more, sees off the danger - a series of overheads eventually getting the better of Djokovic. Deuce.

The Serb absorbing the Muller shots until he unleashes a stonking forehand winner. Break point numero three. Dreamy from Djokovic, securing the break with a muscly crosscourt forehand and the Serb is nearly home and hosed.

Muller reins his opponent in from 30-0 to 30-30, but Djokovic produces a well-timed ace to sneak ahead, and there's no drama to write about. Yet.

From 0-30 to 30-30... Muller getting sucked into a baseline slug-fest... Djokovic pulling his opponent from tramline to tramline and Muller folds like a deckchair in the wind. Break point Djokovic. On the next point, it's the rubber-legged Djokovic, grunting and groaning with every strike, who is forced on the backfoot and Muller comes out on top with a well-worked forehand into the corner. Momentum now with Muller, and a volley brings an end to an intriguing game.

Immense power from Djokovic on the overhead as he starts the game with confidence, but there's been a dip in the Serb's form in the last few games. He coughs up a double fault to give Muller a 15-30 lead, though a thunderclap of an ace brings a stop to any thoughts of David overcoming Goliath. At ease. It was a minor blip, another ace, another hold.

Will wasting four break points in the previous game play on Muller's mind? Nah, no, never. It's the underdog who is currently playing the better tennis and he holds to 30 with little fuss.

At 15-30 Djokovic could be in trouble. The Serb slips slightly on the baseline, which is the cue Muller needs to laser a forehand down the line. Two break points but it all goes awry for Muller as Djokovic forces the game to deuce. A third break point comes his way, though. A shake of the head from Djokovic before the Serb hits a forehand freely and without fear, which kisses the baseline. Oof that was close. Deuce.

Fourth break point. Djokovic's mind has gone for a walk. The pair trade blows from the baseline... Muller's attempts the drop shot but fails to negotiate the barrier. A tap of the temple from Muller. Both players will need to see a shrink at the changeover. Djokovic with the speed of a panther as he scoots from the baseline to the net... he stoops to his shoelaces... cat-like reflexes near the tape to produce an irretrievable volley. Djokovic lives on!

Djokovic happy to fetch and retrieve all day long. At 40-0 Muller seems untroubled, but Djokovic nicks two points - the last a stunning backhand volley from a zany angle. Applause from coach Boris Becker. But Muller is not a man who can be easily bullied and responds with a peach of an ace.

Pressure increasing on Muller with Djokovic quickly rattling through his service games, holding to love once more.

How can Muller battle back from two sets down against the world's best player, a man who has 48 titles and is playing on his favourite court? He probably can't, but he is refusing to surrender meekly.

Muller gifts Djokovic a break point with an iffy volley, but keeps faith with that shot on the next point and it's a backhand volley which gets him out of trouble, putting Djokovic on the defensive and forcing the Serb to net. Danger averted and Djokovic playing catch-up again.

A doff of the hat in Djokovic's direction as he is serving well, with 70% of his first serves hitting the target. The Serb ends a convincing hold with an ace, turning the attention, and the pressure, back on his opponent.

The softest of touches at the net from Muller as he places a backhand volley beyond Djokovic. The 31-year-old will have to come back from the brink if he is to beat Djokovic, but Muller displaying plenty of life at the beginning of this third set, no need for CPR just yet as he holds to love.

Heavy-duty hitting from Djokovic forces Muller into a cul de sac, leaving him with little option but to net on the opening point. The world number 42 then challenges the next point. It looks like an ace to the naked eye and HawkEye shows Djokovic's serve was indeed in by 0.00000mm. Fine margins. Another easy point for the Serb and he has three set point. It isn't quite a procession as Muller hammers a forehand down the line. But the game comes to a predictable conclusion and the Serb growls.
