Jenson Button says he is not allowing himself to dream the title will be his in less than two weeks' time, and admits he is just focusing on each race individually.
"No. Because that is a dream. It is not reality. It could happen, but I have to take every race as it comes," Button told reporters in Singapore about possibility of wrapping up the title in next week's Japanese Grand Prix.
The Briton admitted, however, that he could finally sense the title was coming towards him.
"Yeah. For sure," he said. "The Red Bulls – Sebastian (Vettel) is 26 points behind, which is a lot. But, as Lewis Hamilton pointed out a few races ago – he had 17 points with two races to go and didn't win it in 2007.
"There is so much that can happen. But we have to stay positive and take each race as it comes. I am really excited about the challenge of the next four races.
"The next three are all circuits I enjoy, and then there is Abu Dhabi, which is a new challenge and I am looking forward to because I like driving new circuits."
Button is 14 points ahead of teammate Rubens Barrichello with four races to go, the Brazilian having reduced the gap in every grand prix since Hungary. But Brawn driver Button reckons his mid-season slump is now behind him and he is expecting to perform strongly.
"Yeah. The car has been working well for a few races. Valencia with Rubens winning wasn't a great race for me for whatever reason, but the car was working well there.
"Spa, the car was working OK but not great – even if we were in the race we would have finished fifth or sixth, which would not have been that special. Then at Monza, the car was working well – so it is good the car works well on low-downforce circuits and works on high-downforce circuits. We have our new update here, which should give us a bit more.
"Our pace should be good. I don't think it will move us forward, because there is a lot of team with upgrades – McLaren, Force India, BMW and Renault – but hopefully it will keep us in the game and near the front."
