Andy Murray will begin a challenging end to his season when he takes on Spain's David Ferrer at the ATP World Tour Finals on Monday.
The pair will meet in their opening round-robin match at London's O2 Arena at 14:00 GMT.
Switzerland's Stan Wawrinka and Rafael Nadal of Spain play in the day's other singles match at 20:00.
Murray could play five matches before going to Belgium for Britain's first Davis Cup final since 1978 next week.
He has an 11-6 record against Ferrer, having won their last four matches including a straight-sets victory in Paris earlier this month, but has made the semi-finals only twice in five appearances in London.
Number two ranking within sight
Murray, 28, will switch back to indoor hard courts after spending much of last week practising on clay at Queen's Club in preparation for the trip to Belgium.
The Briton has made no secret of the fact that the chance to win the Davis Cup is his priority, but a good run in London could also lead to him ending the year as world number two for the first time.
"It's been the most consistent year of my career," said Murray, who has won 68 matches and four titles in 2015.
"The Davis Cup has been great, I've won a couple of Masters Series titles, my clay-court season was the best it's ever been.
"I didn't manage to win a grand slam, that's always a bit disappointing, but I've played very consistently through all the tournaments this year and that's something I wanted to do."
Murray, who won the US Open in 2012 and Wimbledon in 2013, reached the Australian Open final this year and the semi-finals at Wimbledon and the French Open.
Positives came from Federer drubbing
Murray's last competitive appearance at the O2 Arena was a 6-0 6-1 drubbing by Roger Federer that ended the Scot's hopes in the group stage last year.
It matched the worst result of his professional career, but a year on Murray has put the experience behind him.
"I don't feel like I have to prove anything to anybody," Murray said. "It was obviously a tough way for me to finish the year but I gained something positive from it.
"I went away and worked extremely hard on my game, and came back and have had the most consistent year of my life, so I don't feel like that match affected me in a negative way at all."
On Sunday, world number one Novak Djokovic began his bid for a record fourth successive end-of-season title with victory over Japan's Kei Nishikori, while Federer beat Tomas Berdych in his opening group match.
