Tennis stars Novak Djokovic and Carlos Alcaraz will face off in a thrilling quarter-final showdown at Melbourne Park.

Unstoppable ten-time champion Novak Djokovic set up a sensational Australian Open quarter-final clash with Carlos Alcaraz after beating Czech Jiri Lehka.

The 37-year-old Serbian beat the 24th seed 6-3, 6-4, 7-6 (7/4) on Sunday at Rod Laver Arena in pursuit of a record 25th Grand Slam Champion.

It takes him into the Melbourne Park quarter-finals for the 15th time, a record he now shares with Roger Federer and ahead of Rafael Nadal and John Newcomb.

The win also extended his own record for Grand Slam quarter-final appearances to 61, three ahead of the Swiss great.

His reward is Tuesday’s showdown with third seed Carlos Alcaraz, who at 21 is already a four-time Grand Slam winner but has never advanced beyond the Australian Open quarterfinals.

The Spaniard initiated the match after Englishman Jack Draper retired after losing 7-5, 6-1 in the last 16.

“In the quarterfinals, I’m going to treat the game like I did in the previous games against him and let’s see,” Djokovic’s Alcaraz said.

“When we saw him play, he seemed young again, so … it’s unbelievable. He’s in really good shape.”

But Alcaraz added: “I’m ready and I know what I have to do in the quarter-finals.”

Djokovic and Alcaraz have met seven times, with the Serbian leading 4-3, including the last meeting in the Paris Olympic final.

They have met three times in Grand Slam tournaments, twice in Wimbledon deciders, with the Spaniard winning both times.

But they have never played at Melbourne Park, where Djokovic has had his greatest success.

Lehka won the qualifiers for the Brisbane International, where Djokovic lost in the quarter-finals, but he was never taken seriously on the big stage.

Djokovic quickly put pressure on his serve and broke after the Czech double faulted in the eighth game of the first set.

Another break of Lehka’s first serve set the tone for the second set, with Djokovic dominating from the baseline.

The young Czech changed his tactics in the third set, pushing Djokovic more towards the net while increasing the intensity of his serve.

The game went into a tie-break and the Serbian sealed the victory with some stunning shots.

Alcaraz was in the lead against Draper when the Englishman withdrew on a sweltering afternoon with “really sore spots in multiple areas”.

No. 15 seed Draper needed five sets to win his first three matches in Melbourne, coming from behind in all matches to stay in the match before eventually catching up.

“It’s not the way I wanted to win. But obviously, I’m happy to play in the quarterfinals again in Australia,” Alcaraz said.

“Physically, I feel good. So, going into the second week of a Grand Slam, it’s important to feel good physically because the competition is tougher now.”
