The race for the silverware is over - now it's a dash for the cash at the Masters Cup in Shanghai.
Nadal is out of contention so can Federer make it three in a row?
It's been a long, hard season in the tennis world. But the race for Grand Slams is now over - and the scrap for the big bucks can commence.
There is $4.45million (£2.8m) to be shared out in Shanghai with the best part of £850,000 on offer to a champion who remains undefeated. And with Rafael Nadal taking a breather, the competition is there to be won.
Skysports.com gives a rundown of this year's hopefuls.
Roger Federer
The world No.2 has long been chalking his name on the all-time great lists of tennis - and could add a new one to his collection if he wins in Shanghai. It would make him one of three to have won the season-ender on five occasions with Ivan Lendl and Pete Sampras - and only Lendl has won three back-to-back.
An average season by his standards has seen him claim just the one major title - the US Open, where he beat Andy Murray in the final - but he'll be keen to set the record straight, especially with arch-nemesis Rafael Nadal out of the running.
The good news for him is that Nikolai Davydenko, Jo-Wilfried Tsonga and Juan Martin del Potro have all never beaten him. The bad news is they are all in the other round robin group, which could make his bid for the undefeated champion bonus a touch harder.
Novak Djokovic
Serbia's favourite tennis son started the season like lightning; winning the Australian Open on his debut attempt and then picking up Masters Series titles at Indian Wells and Rome.
But the world No.3 tailed off after that, as he finished runner up at Queen's, Cincinnati and Bangkok; although he did claim a bronze medal at the Beijing Olympics.
Now 21, he'll face Davydenko, Tsonga and del Potro in the group stage, and he'll be hoping to do better than last year where he failed to win a single match.
Andy Murray
What a year this has been for the British No.1. A first grand slam singles final, five titles - two back-to-back - and a career-high ranking of fourth in the world.
The 21-year-old enters his first Masters Cup in the form of his life with 25 wins from his last 28 matches, he has also beaten all but two of his Masters Cup rivals this year: Tsonga and Andy Roddick.
Murray is the first Brit to reach the end of season event since Tim Henman did in 2004 - and if he wins, it'll be the first triumph for the country since Greg Rusedski won the Grand Slam Cup in 1999.
Nikolai Davydenko
Davydenko is a seasoned campaigner at this end of year soiree having qualified for the fourth straight time this year.
The Russian finished the ranking period fifth in the world despite failing to get past the fourth round of any of the grand slams. That was mainly due to a Masters Series win at Miami with minor titles gathered at Poertschach and Warsaw.
Davydenko's trouble hasn't been confined to on-court matters either, having spent the year under investigation by the ATP after betting accusations were made following a 2007 match against Martin Vasallo Arguello.
He was finally cleared in September and no doubt breathed a second sigh of relief when the draw for the Masters Cup kept him away from Federer. His record against the reigning champ is played 12, lost 12.
Andy Roddick
The undeniable highlight of the world No.6's season to date was beating first Nadal then Djokovic to win the Dubai Open back in March.
But after that, there's not been much for the 26-year-old to write home about. He had to pull out of the French Open with a sore shoulder, then steered clear of the Olympics to focus on the upcoming US Open, where he made the quarter-finals.
The A-Rod has reached the semi-finals of the Masters Cup three times - but might find it tough this year alongside Federer, Murray and Gilles Simon.
Jo-Wilfried Tsonga
When Tsonga beat Murray in the first round of the Australian Open, the British public were horrified.
But the shock eased when he made the final of the tournament, and just kept on improving. He finished the year ranked number seven in the world having started as number 38, and beat David Nalbandian in a winner takes all final in Paris to earn qualification for Shanghai.
The young Frenchman has hit form at the right time, winning a first tour title at the end of September then following up with Paris to break into the top 10 for the first time. He could prove a tricky customer.
Juan Martin del Potro
If Tsonga's rise has been impressive, Martin del Potro's has been nothing short of meteoric.
The 20-year-old Argentinian went from 81st in the world in April to eighth in November, winning four tournaments in a row and helping his country to the Davis Cup final.
His inclusion in Shanghai marks a mini coup in beating countryman Nalbandian to qualification.
Gilles Simon
Could this be the luckiest man in tennis? Quite possibly if he can put some results together.
The Frenchman was called up last week to replace the injured Nadal, instantly doubling his stand-by fee to a participating fee - and with $100,000 up for grabs with each round robin match victory, he may be able to further cash in on Nadal's injury.
He's picked up three titles this season but has twice been beaten by Murray, most recently in the Madrid final, so that's one match he won't be looking forward to.
Missing... Rafael Nadal
The world number one has had a dream like season - winning the French Open again, and then doubling up and beating grass court genius Federer in the Wimbledon final.
Add to that a hat-trick of Masters Series titles, two other grand slam semi-finals and the small matter of Olympic gold in Beijing, and you can see why he's been feeling the strain. He pulled out of the season finale last week citing fatigue.
