Andy Murray is in the midst of a superb season and is now determined to dethrone Novak Djokovic as world number one.
Murray, who currently occupies second place on the rankings, triumphed at Wimbledon this year and won a gold medal at the Olympics in Rio de Janeiro. He has also won two ATP World Tour titles and reached the final of the Australian Open and Roland Garros.
With Djokovic having faltered in the second half of his season, Murray has a chance to close the gap between him and the Serb at the China Open in Beijing this week.
"I think obviously trying to reach number one is a goal," Murray said. "I think most of the players that are near the top of the game would like that.
"I've never been there and it's something I would like to do for the first time, which is maybe more of a motivation for me than some of the guys that have been there before.
"But I want to just try and finish this year strong from a personal point of view. It's been my best season to date, and I want to try to finish it as best as I can."
Murray arrived in China on Sunday morning and there was some concerns about whether he would feature in the tournament in Beijing due to a thigh injury he picked up while representing Great Britain in their Davis Cup semi-final loss to Argentina.
The 29-year-old, though, has no plans to pull out and will open his China Open campaign against Andreas Seppi on Tuesday.
Following the China Open, Murray also plans to compete in the Shanghai Rolex Masters next week.
"I obviously planned on playing here the whole year," he said. "I needed to take quite a few days off after the Davis Cup to try and let my injury heal and to rest.
"I needed a break anyway and I haven't been able to practice as much as usual coming into an event like this. But I feel healthy, my leg feels good.
"I only arrived here [yesterday]. I'll try and get some good practice in the next couple of days and hopefully have a good tournament.
"I think this week I need to be realistic with maybe how I'm going to play. I have very few days of practice coming in here and I'm not putting too much pressure on myself right now.
"I need to get a few good days of training in here, try and get used to the conditions. If I can get through my first match or so, I'll start to feel better, then re-evaluate my chances of going far in the event."
