John McEnroe Group
Andy Murray - Unperturbed by playing in a golden era alongside some of tennis’ all-time greats, Murray has taken the momentous step from No. 2 to No.1 in the world after a stunning year. He has reached three of the four Grand Slam finals, winning a second Wimbledon title along the way, and defended his Olympic gold medal. He will go into the tournament on an 18-match winning streak, although he has played more matches than any of the other seven players this season and has never won the ATP World Tour Finals.
Stan Wawrinka - Ranked third in the world, Wawrinka has won just as many Grand Slams in his career as Murray, having lifted his third major title at the US Open in September. He is nowhere near as consistent as Murray or Djokovic, but is a player for the big occasion and on his day is arguably better than anyone.
Kei Nishikori - Nishikori is fifth in the rankings following another impressive year, when he beat Murray on his way to the US Open semi-finals and bagged Olympic bronze. The Japanese 26-year-old is an exceptional shot-maker who is well suited to indoor courts, but his serve could be vulnerable in a tough group.
Marin Cilic - Seventh in the world and a hugely powerful player, Cilic claimed his biggest title of 2016 when he beat Murray in the final of the Cincinnati Masters. He has steadily got better throughout the year and is a dark horse to go all the way, although he may also have one eye on Croatia’s upcoming Davis Cup final against Argentina.
Ivan Lendl Group
Novak Djokovic - The dominant force in men’s tennis for the past few years, there was no sign that Djokovic would surrender his No.1 ranking when he won the French Open in June to complete the full set of Grand Slam titles. However, he has suffered a series of early exits over the past few months and has had one or two injury issues. He will need to go through the tournament unbeaten to reclaim top spot, but can take confidence from winning the event for the past four years.
Milos Raonic - The Canadian world No.4 reached the Wimbledon final and has been consistent all the way through 2016. He has the biggest serve of anyone in the tournament and will be a particular threat if the courts play quickly, otherwise it is hard to see him making the final.
Gael Monfils - One of the most entertaining players on the circuit for years, Monfils has finally pushed on in 2016 to qualify for the World Tour Finals for the first time at the age of 30. Now ranked sixth in the world, the flamboyant Frenchman’s match with Raonic will be key to his hopes of getting to the last four.
Dominic Thiem - Ninth in the world, Thiem will take his place in London due to the absence of the injured Rafael Nadal. The Austrian was exceptional for the first half of the season, winning titles on clay, grass and hard courts, but his crammed schedule has caught up with him in the last few months and he looks too fatigued to mount a serious challenge.
Murray is the man in form and favourite to win, but the draw has been far kinder to rival Djokovic. The Serbian is not only in the seemingly more-straightforward group, but he would also have a day’s rest before the semi-finals on Saturday 19th November, with Murray’s John McEnroe group not being concluded until the Friday evening. Djokovic also has a far greater record at the World Tour Finals than anyone else; he is a five-time champion, while none of the other seven competitors have even made a final.
Apart from Wawrinka, it is hard to see beyond a dream final showdown between Murray and Djokovic. They have not played each other since the French Open, but if they meet here the No.1 ranking could be on the line, and there's very tempting price boost on Murray to beat Djokovic in the final at 4/1.
