With the line-up confirmed and the draw completed, the ATP World Tour Finals are soon to get underway at the Pala Alpitour in Turin.
Play begins in Italy on Sunday afternoon in Italy as the seven contenders try to dethrone Novak Djokovic.
As the world's best eight male players prepare to battle it out in Italy, here is a look at each player competing in the event.
There is no better place to start than with defending champion Novak Djokovic, who is looking to claim a record seventh ATP World Tour final title this month.
The world number one spot also beckons for the Serbian, who has won the Cincinnati Masters, the US Open and the Paris Masters since late August.
He takes the top seed at the event and is in the Green Group along with Jannik Sinner, Stefanos Tsitsipas and Holger Rune.
Djokovic's closest competitor, at least as far as the outright odds are concerned, is Spaniard Carlos Alcaraz.
It has been another strong year from the 20-year-old, who was runner-up at the French Open and winner at Wimbledon and he is preparing for his debut at the ATP World Tour finals.
He has won 63 of his 73 matches on the ATP Tour this year and is the tournament's second seed.
Fourth seed Jannik Sinner will also be looking to make an impact in Turin and he will be hoping to make the most of a home crowd.
Sinner claimed the Vienna Open last month and this will be his debut in the tournament as a direct qualifier with the Italian having played as an alternate in 2021.
It has been a patchy but overall positive campaign from Daniil Medvedev, who has claimed five titles on the ATP Tour in 2023.
Runs to the finals of the US Open, ATP Beijing and Vienna Open recently mean he should head to Turin in a positive mood.
And Medvedev may feel as though he has a point to prove after losing all three of his matches at the event in 2022.
Having only qualified for the event earlier this month, Tsitsipas is an outsider at the ATP World Tour Finals in Turin and crashed out in the group stage of the tournament last year.
The Greek ace did, however, make the semi-finals of the Vienna Open and Paris Masters and will be hoping to build on those performances in Italy.
Andrey Rublev was a surprise package at the ATP World Tour Finals last year, finishing above Tsitsipas and Medvedev in the Red Group to reach the knockout stage.
He was beaten in the end by Casper Ruud but could go well again after matching or bettering his best performances at the Australian Open, Wimbledon and the US Open this year.
Experienced German Alexander Zverev has had an up-and-down season, posting 53 wins and 26 defeats on the ATP Tour and claiming two titles in the process.
Making this event is an achievement in itself and it would be a surprise to see Zverev go deep in Turin.
Holger Rune can be a tricky opponent, having nicked a set off Djokovic in the Paris Masters quarter-finals earlier this month, the eighth seed opens against the Serbian in Turin.
He too faces an uphill battle at the ATP World Tour Finals and has just one title to his name in 2023.
