World No1 Novak Djokovic won the 2014 crown after Roger Federer pulled out of the final match due to injury.
The ATP season finale in London features only the world’s best eight singles players and doubles teams.
Last year, Djokovic, Federer, Stan Wawrinka, Kei Nishikori, Tomas Berdych, Andy Murray, Marin Cilic and Milos Raonic contested the prestigious end-of-season singles prize.
Home favourite Murray is likely to feature again after the Scot valiantly agreed to play an exhibition match against Djokovic following the cancellation of last year’s final.
Rafael Nadal was absent after opting to undergo surgery to remove his appendix towards the end of the 2014 ATP season.
Despite the disappointment of not being able to play the 2014 final against Djokovic, Federer insisted that he was already looking forward to 2015 after last year’s tournament.
“I’m definitely looking forward to 2015,” said Federer last November after the ATP World Tour Finals.
“It’s been a great year for me this year. I played some wonderful tennis, very consistent [and] very physical as well.”
Tickets for the event are on sale on viagogo, the official premium ticketing partner and ticket exchange partner of the Barclays ATP World Tour Finals.
