Andy Murray admits his maiden grand slam triumph at the US Open will ensure that he heads into the ATP World Tour Finals with a more relaxed mindset.
Having claimed gold at the Olympics earlier in the summer, the Scot broke his major duck in New York two months ago with a thrilling victory over Novak Djokovic.
Murray has been drawn in Group A with the Serb for next week's showpiece at the O2 Arena, along with Tomas Berdych and Jo-Wilfried Tsonga.
Berdych will be first up for the British number one on Monday afternoon, but he insists there will be less pressure on his shoulders this time around because of his exploits at Flushing Meadows.
"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," stated Murray.
"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."
Of his encounter with Berdych, who he beat in the semi-finals at the US Open, he added: "I knew my first match was going to be against Berdych or (Juan Martin) Del Potro. Obviously there are differences in their games but they're both big guys, bit hitters, flat hitters of the ball and can generate power and winning shots from all parts of the court.
"You need to try to use some variety. Against all the guys here you're going to have to play a top-quality match to win."
Reunited with Lendl
Del Potro was drawn in Group B with defending champion Roger Federer, who will lose the number one ranking to Djokovic on Monday, fourth seed David Ferrer and eighth seed Janko Tipsarevic.
Murray's group looks significantly tougher but he played down the differences, saying: "Indoors Roger has been the best player over the last couple of years.
"Juan won two tournaments indoors just before Paris. If everyone plays their best tennis, I don't think one group will necessarily be tougher than the other."
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: "I always enjoy having him around. He's been a great asset to me and all the guys I work with.
"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."
