Justin Rose believes he is capable of climbing to the top of golf's world rankings, but acknowledges he will need to put together a "very special run".
The 35-year-old Englisman is fifth in the standings at present, behind Bubba Watson and the elite trio of Jordan Spieth, Jason Day and Rory McIlroy, who have each held top spot in 2015.
However, as he heads into the European Tour's season-ending DP World Tour Championship still in contention for Race to Dubai glory, Rose is confident he has what it takes to push further up the rankings.
"I feel like it's a realistic goal, the way I'm playing, the consistency in which I'm playing, I feel like if I get a hot run and suddenly get on a run where I win a couple of majors and a couple of other tournaments, I'm right there to be world number one," said the 2013 US Open champion.
"You see Jason Day and Jordan and Rory have been trading it around this year. Obviously those are guys I play golf with a lot and you see their games and you sometimes feel there's no reason why I can't play to that level as well.
"The world number one, I'm still a long way away from it, it needs a very special run but I believe it's possible."
Rose boasts 14 top-15 finishes this year and has not been outside the top seven in his last four events.
He added: "A player, like Jack Nicklaus for example, has always said that his bad is better than everyone else's bad. He was able to manage his game and that created a lot of winning opportunities for him.
"I feel like my consistency has got a lot better and that's what I'm most pleased about, I would say, that my overall level, my mean average, has gone up this year.
"Your good is always good but I would say my average has gotten better. So that's pleasing.
"There are always areas you can work on. I would say chipping would probably be an area I'd like to improve or just to develop a little more confidence in. That's something I can do over the off-season."
