Novak Djokovic remains the man to beat on the ATP Tour - but ready to take the baton from him in the coming years is Carlos Alcaraz, arguably the most exciting talent in world tennis right now.
Still in the infancy of his career, Alcaraz has rapidly risen up the ranks since his ATP debut in 2020, having won his maiden Wimbledon title last year.
Alcaraz won his first Grand Slam titles at the US Open back in 2022, having eased past Sebastian Baez, Federico Coria and Jenson Brooksby in the first three rounds without dropping a set.
After wins over Jannik Sinner and Frances Tiafoe, he set up an eye-catching final with Casper Ruud, defeating the Norwegian to become the youngest number one in the history of the ATP rankings.
And last year, Alcaraz followed up with his second major at Wimbledon, coming out on top at the All England Club after a five-set epic with Djokovic in the final.
With titles picked up on the hard, clay and grass courts, Alcaraz has shown himself to be an immensely versatile player in the last few years and starts 2024 with 12 ATP titles to his name.
That haul has featured four Masters 1000 triumphs, coming in Miami, Indian Wells and twice in Madrid.
Alcaraz's first title win on the ATP Tour came in the form of the Croatia Open in July 2021 and his most recent final appearance was at last season's Cincinnati Masters when he lost to Djokovic.
He also claimed his fourth ATP 500 title at Queen's last June as part of the build-up to his Wimbledon triumph.
Heading into the season's first Grand Slam, the Australian Open, Alcaraz is in second spot in the ATP rankings, just above Daniil Medvedev and below Djokovic.
However, the Murcia-born ace moved up to world number one after his US Open success in 2022, finishing that season top of the rankings.
Although this is only Alcaraz's fourth year on the ATP tour, he has already racked up just over $27million in prize money, putting him 15th in the all-time earnings standings.
Born 5th May 2003, Alcaraz is still only 20 years old with the best years of his career surely ahead of him.
Alcaraz now resides in Villena in the Valencian Community of Spain but was born in El Palmar in Murcia, Spain.
After having to withdraw from the Grand Slam last season due to a hamstring injury, Alcaraz is in line to feature in Melbourne this time around.
The Spaniard will be eager to improve on his best previous performance at the Australian Open which was a run to the third round in 2022.
