It will be a more relaxed Andy Murray who takes to the court at the O2 Arena on Monday as the Scot prepares to compete on home soil for the first time since winning the US Open.
Murray finally broke his grand slam duck in New York two months ago and is one of the favourites to end his season with silverware at the Barclays ATP World Tour Finals.
"There's always pressure at all of the major tournaments you play but I feel a little bit more relaxed coming in this year than I have in previous years because I managed to win the US Open," Murray said.
"But the only thing I can guarantee is that I'll give 110% on the court, fight as hard as I can until the end of all the matches and see where that gets me. Hopefully it'll get me a few wins."
The draw put Murray in Group A along with top seed Novak Djokovic, Czech Tomas Berdych and last year's finalist Jo-Wilfried Tsonga, and it is Berdych who will be the world number three's first opponent on Monday afternoon.
Berdych was the man Murray defeated in the semi-finals at Flushing Meadows in horrendously windy conditions before ending a four-match losing streak in grand slam finals with a five-set victory over Djokovic.
Murray has been reunited with coach Ivan Lendl this week for the first time since that momentous night in New York.
Lendl only travels with his charge for certain tournaments and stayed at home in the US while the Scot played in Tokyo, Shanghai and Paris.
Murray, who is making his fifth appearance at the Tour Finals, said: "He's been very easy to work with and helped me and everyone at the big events this year and he's helped me come back from some tough losses and finish the year in the slams very well. I hope we can have a good tournament."
The tournament features the best eight players from the season, although Rafael Nadal is continuing his recovery from a knee injury, handing Tipsarevic an automatic place. The only different face from last year is Juan Martin Del Potro, who is back in the field for the first time since his US Open-winning season in 2009, when he reached the final of the inaugural O2 tournament.
