Andy Murray has set his sights on victory at the ATP World Tour Finals to complete a stunning year after celebrating becoming world number one by beating John Isner in the Paris Masters final.
The Briton battled to a 6-3 6-7 (4-7) 6-4 triumph in France on Sunday to secure his first Paris title and immediately turned his focus to the season-ending tournament in London.
"I'm not so much thinking about the year-end number one," he told Sky Sports.
"I just want to play well at the O2. I feel like some of the years I haven't always played my best tennis and haven't done myself justice.
"It's not always a guarantee against the best players in the world, but I don't want to finish the year on a bad note, having not played well there."
Reflecting on his hard-fought win over Isner, which came a day after the two-time Olympic champion rose to the summit of the rankings ahead of Novak Djokovic following Milos Raonic's semi-final withdrawal, Murray added: "It was an unbelievably hard match.
"I had very few opportunities, it was tough to lose the tie-break in the second set, but John served unbelievably well and came out with great volleys as well.
"I was lucky he missed a few serves in the last game and I managed to hit a few passing shots, but it was a great way to win the match.
"I had a few chances and he served great on the first couple of break points I got.
"In the last game he just missed a few serves, it felt like he served amazing, maybe in the low 70s or early 80s [percentage] and I wasn't getting many opportunities.
"In the last game I did and I was able to capitalise."
