The Spaniard became the youngest man to complete the career Grand Slam when he beat 24-time major winner Novak Djokovic 2-6 6-2 6-3 7-5 in the Australian Open final this month.

Novak Djokovic said it had been "a great ride" and "God knows what happens tomorrow" after losing Sunday's Australian Open final to Carlos Alcaraz.

Carlos Alcaraz said having Rafael Nadal watching in the crowd helped drive him to a maiden Australian Open title on Sunday and made the win "even more special".

Alcaraz has immense respect for Nadal and Djokovic, but the world number one's hero growing up was Roger Federer.

Carlos Alcaraz swept past Novak Djokovic to win his first Australian Open on Sunday and become the youngest man to complete a career Grand Slam, denying the Serbian great an unprecedented 25th major.

Carlos Alcaraz said he did not think he had cramp initially when he took a medical timeout that left Alexander Zverev fuming in their marathon Australian Open semi-final on Friday.

Novak Djokovic called it one of his best performances in a decade after outlasting Jannik Sinner early Saturday in a five-set marathon to set up an Australian Open final against Carlos Alcaraz.

Carlos Alcaraz battled past Alexander Zverev and through cramp Friday in five gruelling sets to reach his first Australian Open final and move within a match of becoming the youngest man to complete a career Grand Slam.

Novak Djokovic says two-time defending champion Jannik Sinner is the "absolute favourite" in their Australian Open semi-final on Friday but vowed to bring his "A-game" and pull off an upset.

Record-shattering Novak Djokovic said he was "hanging in there" after becoming the first player to win 400 Grand Slam matches Saturday on his way into the last 16 at the Australian Open.

He will become the youngest man to win all four majors should he push on and make his breakthrough.

Six-time Grand Slam winner Carlos Alcaraz was put through his paces by German journeyman Yannick Hanfmann on Wednesday before swatting him aside to book his place in the Australian Open third round.

Novak Djokovic embarked on his latest quest to win a record 25th Grand Slam by easing to an ominous straight-sets victory Monday at the Australian Open.

Carlos Alcaraz kicked off his latest bid for a career Grand Slam by dismantling unseeded Australian Adam Walton 6-3 7-6(2) 6-2 in the first round of the Australian Open on Sunday, as the world number one showcased the power and precision befitting a player chasing history.

Novak Djokovic said Saturday he likes his chances at the Australian Open despite "missing a bit of juice" in the legs, declaring he can still beat anyone on his day.

Carlos Alcaraz beat great rival Jannik Sinner in a light-hearted sell-out exhibition match in South Korea on Saturday ahead of the Australian Open.

World number three Alexander Zverev admitted on Saturday that he has "a lot of catching up to do" to challenge Carlos Alcaraz and Jannik Sinner.

The world number seven is yet to beat either player and admits he has to find new weapons to challenge the Spaniard and Italian who have shared the last eight Grand Slam titles.

With six Grand Slam titles under his belt to Sinner's four, Alcaraz will look to eclipse Nadal and become the youngest man to complete the set of all majors when he heads Down Under in the New Year.

Men's tennis world number one Carlos Alcaraz announced on Wednesday he is splitting from his coach Juan Carlos Ferrero after seven hugely successful years together with assistant coach Samuel Lopez taking over.
