Rublev’s match going to a fifth-set tiebreak means there has been a slight deley to Djokovic vs De Minaur, which is set to get underway at around 8:30am. Djokovic looking to extend his 24-match win-streak at the Australian Open but is looking forward to the test of facing a home player in Melbourne.

“It’s a big challenge of playing an Aussie guy here in front of his home crowd,” Djokovic said. “I’m sure that the atmosphere will be electric, and he’s going to have a lot of support, and he’s going to be pumped to try to win the match.

“But I’ve had experiences before. I played Lleyton Hewitt here. I played some big Aussie players, so I know how that feels. I know what to expect, so to say, in terms of atmosphere, the match itself.

“The fact that I never faced him is also challenging for both me and him. I think we don’t know much about each other’s games, but still we know each other pretty well because he’s been around for quite a few years. I’ve watched him play numerous times. I know how he plays.”

Rublev is asked about his quarter-final: “No one wants to play Novak,” he says, seemingly forgetting that the Serbian is facing an Australian Alex De Minaur in the next match. “I forgot, sorry!”

What an extraordinary finale to Andrey Rublev vs Holger Rune! It went to a match tiebreak, with the 19-year-old Rune storming to a 5-0 lead in the race to 10 points. But Rublev stormed back, winning nine of the next 11 points to bring up two match points. From there, Rune saved both - the second with a stunning backhand winner.

But Rublev responded again - the Russian was a break down with Rune serving for the match, too - and set up another match point. He got a massive slice of luck with a dead net-cord on match point, but that was a brilliant contest.

“It’s not a rollercoaster, it’s like putting a gun to your head,” jokes Rublev. “Rollercoasters are easier. Never in my life have I won a match like this.”

Rublev faces the winner of Djokovic vs De Minaur.

Novak Djokovic speaking about his hamstring injury, following his straight-sets win over Grigor Dimitrov: “It kind of always starts well in last few matches, including this one, and then some movement happens and then it gets worse. Pills kick in, some hot cream and stuff. That works for a little bit, then it doesn’t, then works again.

“It’s really a roller coaster, honestly. It requires a lot of energy that is being spent from my side mentally and physically, as well, to deal with the match with my opponent and also with not ideal physical state.

“But it is what it is. It’s kind of a circumstances that you have to accept. I’m just very grateful that I’m actually able to play. The way it looked just before the tournament started, I thought that it wouldn’t be possible. I’m still here and still holding on.”

Novak Djokovic vs Alex De Minaur is the headline match on the Rod Laver Arena and will take place from 8am GMT, following the contest between Andrey Rublev and Alex De Minaur.

Poland’s Magda Linette reached her first Grand Slam quarter-final with a 7-6(3) 6-4 upset of fourth seed Caroline Garcia in just under two hours at Rod Laver Arena.
