Rafael Nadal will bid to cap off a fine season at the ATP Finals in London but will face a stern challenge from Roger Federer with six other players hoping to surprise the odds.
Nadal, the year-end world No 1, has won six titles this season, including the French Open and US Open, and despite reaching the season finale for a 13th successive year, has never won the title.
Federer, the Spaniard's biggest challenge to the title in London, heads to The O2 with a season-best seven titles and targeting a seventh year-end title.
Eight different countries are represented in the eight-man singles field for the second successive year and you can watch every single game, set and match live on Sky Sports, as well as stay across all the action and reaction on our digital platforms. Here's how…
