Novak Djokovic extended his massive lead at the top of the ATP world rankings, which were released on Monday, following his fourth straight victory at the season-ending World Tour Finals in London.
The Serb’s straight sets win over Roger Federer in Sunday’s final pushed his advantage over world number two Andy Murray to almost 8,000 points.
British number one, Murray, who is gearing up for this week’s Davis Cup final against Belgium, is guaranteed to finish the year number two for the first time, which should give him the second seeding at January’s Australian Open.
Beaten finalist, Federer, and Swiss compatriot, Stan Wawrinka, are third and fourth respectively – while Rafael Nadal completes the top five.
Meanwhile, Federer has warned Djokovic he will find it hard to replicate his incredible 2015 campaign.
Federer was Djokovic’s last victim of the year as the Serb romped to a 6-3, 6-4 victory in the final of the ATP Tour Finals on Sunday.
It was the 28-year-old’s 11th title of a golden year that saw him win 82 of his 88 matches, reach all four Grand Slam finals and win Wimbledon, the Australian Open and the US Open.
“It’s hard to play at this pace all the time. You are talking about narrow margins, a break point here and there can change the whole outcome,” Federer said.
“You can’t always be on the winning side. Margins are very small at the top.
“That is why this year of Novak’s is amazing. I’ve been there, Rafa (Nadal) has been there. We both know how hard it is to back it up year after year.
“It’s not the first good year for Novak. Certainly he’s going into next year with massive confidence. He’s playing great.
“It’s going to be hard for him to have a bad year, but you can’t just repeat a year like this.
“It takes a lot of effort. You’ve got to be in shape physically with no injuries whatsoever. Mentally you have to be at your peak at all times. It’s not as easy as it seems sometimes.”
