ATP World Tour Finals: Daily schedule as Andy Murray reaches semi-finals
ATP World Tour Finals will see the sport's best tennis players descend on London once again in November - so here's everything you need to know about the line-up.
When is the tournament?
The 2016 World Tour Finals will run from Sunday November 13 to Sunday November 20.
Who will compete in the World Tour Finals?
The top 8 points scorers in the ATP Race to London automatically qualify for the finals.
Novak Djokovic, Andy Murray, Stan Wawrinka, Milos Raonic, Kei Nishikori and Gael Monfils all scored enough points over the season to guarantee a spot in the tournament.
Marin Cilic completed the line-up by reaching the quarter-finals of the Paris Masters with a win over David Goffin.
Roger Federer is 12th in the table and took the rest of the season off after a knee injury suffered at Wimbledon, meaning he will miss the finals.
Nadal will also miss the competition after he was forced to pull out with a wrist injury.
The tournament will also feature the eight best men's doubles teams in the world.
Tennis ace Djokovic seeks to rediscover pleasure of playing
France's Pierre-Hugues Herbert and Nicolas Mahut currently top the rankings and will be among the favourites to lift the title.
Andy Murray's brother Jamie Murray will take part having won both the Australian and US Open doubles with Brazil's Bruno Soares.
Bob and Mike Bryan will also be a major attraction for tennis fans. The American twins are third in the points race and have 16 men's doubles Grand Slam titles as well as having won the World Tour Finals four times.
