Roger Federer and Novak Djokovic are the favourites to win the ATP Finals.
The two tennis stars have won the competition 11 times between them, with Djokovic just win one behind Federer.
The Serbian is hoping to win his fifth tournament in four months after returning to the top of the world rankings.
And Federer believes Djokovic is the favourite to take home the final piece of silverware of the season.
“Dominating the field is not something that comes very easy,” Federer said.
“I think only Novak can say ‘if I play as well as I have the last few months, maybe I can also win the World Tour Finals’.
“The best of three set matches indoors, the margins are slimmer. It can slip fast.
“I hope I don’t go on vacation with three losses, put it that way.”
Meanwhile, Kevin Anderson reckons the remaining players behind Federer and Djokovic all have a fighting chance of progressing to the semi-finals
“We knew we was going to be in a group with Federer or [Novak] Djokovic so it was going to be tough either way,” Anderson said.
“Everybody has a chance of beating everybody at this level.
“Besides the guys who have won this tournament many times, things are pretty even.”
