After winning what was the match of the tournament so far, Novak Djokovic heaped praise on his opponent Carlos Alcaraz.

"First I want to say i give my utmost respect and admiration for Carlos Alcaraz," he said.

"What a terrific guy and even better competitor. I am sure we are going to see a lot of him and more than perhaps I would like," he added while laughing.

Djokovic, like many of us watching at home, wanted this match to be the final.

"I just wish this match today was the final."

"One of the most epic matches I have played on this court and on any court really."

Looking ahead, Djokovic was cagey with his injury saying he doesn't want to give too much away to semifinal opponent Alexander Zverev.

But he did admit he may have pulled out if he lost the second set.

"The medication started working, I had to take another dose, I had to.

"If I lost the second set I am not sure if i would have continued playing."

Despite an impressive performance on the pitch, Djokovic was not impressed with his kids being awake at 1am.

"I am surprised my kids are still here.

"I love you and thank you for supporting me but it's 1am, when are you going to sleep tonight?"

Novak Djokovic has defeated Carlos Alcaraz in what will likely go down as an Australian Open quarterfinal classic.

The 10-time champion once again showed his skills and tennis-wisdom to overcome Alcaraz in four sets.

After dropping the first set, Djokovic turned things around to win the next three-in-a-row.

The scorecard read 4-6, 6-4, 6-3, 6-4.

Both players are exhausted after that.

And both players just put on a show for tennis fans around the world.

Alcaraz showed exemplary skill throughout, often times hitting some stunning winners.

However the experienced Djokovic proved once more that he is one of the best to ever do it.

He moves on to the semifinals, and it will be his 50th grand slam semi.

Some stat. Some player.

The first chance for game, set, match is upon us.

Novak Djokovic finds himself 5-4 up here in the fourth set and is now serving for the match.

Carlos Alcaraz had a chance to break back there but Novak Djokovic kept his cool to save two break points.

Up 15-40, Alcaraz was in control but Djokovic showed nerves of steel to put himself within touching distance now.

He is up 5-3. The finish line is in sight.

Every single point is tense and almost always ends in a ridiculously well-placed winner, whomever hits it is the only variable.

This is tennis deserved of a grand slam final, aren't we lucky to get it in a quarterfinal?

Carlos Alcaraz has just saved a break point in incredible fashion.

He and Djokovic played a 33-point rally in which he forced an error to save the break.

He then held his serve to keep him in this match.

Both players were exhausted after that game and fair enough too, they are putting on a show for us!

Djokovic now leads 4-3 and has the finish line in sight.

But the 3rd seed Spaniard is doing all he can here to claw back some footing in this potentially deciding fourth set.

On the winners he does hit he is pleading with the crowd to get behind him.

The crowd is erupting here.

Novak Djokovic has been running Carlos Alcaraz around the court in the last game.

He gestured to the crowd to cheer louder.

The veteran has shown his experience and quality to stay in front here in the fourth.

Alcaraz, in truth, looks exhausted, but it must be said he is still producing quality shots and incredible tennis. 

The problem is Djokovic is doing one better.

In case you were wondering just how infuriated Carlos Alcaraz is at the moment.

Djokovic leads 2-0 in the fourth set here.

 Novak Djokovic is absolutely tuned in here.

He has broken Carlos Alcaraz in the first game of the fourth set.

The Spaniard is frustrated. He must be thinking how is Djokovic doing this.

It also looks like he is starting to cramp in the right leg.
