Novak Djokovic has already established himself as one of the greatest tennis players in history.
And the Serbian's record seventh ATP Finals success in Turin, leaving him one clear of Roger Federer, saw him underline those credentials even further.
That capped a historic November of 2023 for the Serbian superstar who became the first man to win 40 ATP Masters 1000 titles in the Paris Masters.
Rafael Nadal is next on the all-time list with 36.
Djokovic also ended 2023 on top of the world rankings, the eighth time he has been year-end number one with Pete Sampras next on six.
In September, his US Open 2023 win saw him match Margaret Court's Open era record of 24 Grand Slam singles titles. He also holds the record for most Slam final appearances with 36, two clear of Chris Evert's previous record.
Djokovic has now won a total of 98 ATP Tour events and is the only man to hold all four Slam singles titles at the same time since Rod Laver's 1969 calendar Grand Slam.
He is also unique in having a Career Golden Masters with victories in all nine ATP Masters tournaments that have been in operation during his career.
On 27 February 2023, Djokovic recorded his 378th week as men's singles world No. 1 to set the all-time record, man or woman, for weeks spent at the top of the tennis rankings.
And at Paris 2024, he beat Carlos Alcaraz to secure the only accolade which had eluded him until then - an Olympic gold medal.
