Lewis Hamilton could wrap up the F1 Drivers' Championship this weekend if he wins the US Grand Prix and Sebastian Vettel finishes 6th or lower.
The three-time world champion - who was beaten to the title by Nico Rosberg last year - has opened up a 59-point lead on his nearest challenger.
Hamilton's relationship with Rosberg was in tatters by the end of their time together at Mercedes.
Valterri Bottas replaced the German driver and has formed a much more amicable working relationship with the British driver.
The 28-year-old Finn - who has suffered a downturn in form since the August break - is 3rd in the current F1 standings and lies only 13 points behind Vettel.
Despite being outshone by his Mercedes teammate, Bottas still believes he has what it takes to fight Hamilton for glory in the future.
“Of course I believe in myself and I believe learning from all the defeats, learning from the races, that I have been off the pace compared to him [Hamilton],” said Bottas.
“By working hard, by taking every point I can take to improve and work with myself and the team, I believe it is possible. I believe in my abilities, I believe in myself. And the future is still ahead of me, so I am sure.”
The major difference between Bottas and Hamilton
Speaking ahead of the US Gran Pix, Bottas acknowledged why the more "adaptive" Hamilton has out-performed him this season.
"I’ve noticed we have a bit of a different driving style,” Bottas continued. “At some moments the car has been tricky and he has been better at dealing with it.
“I think also with my natural driving style I have been in places struggling a bit more with the car, so he has bee able to adapt to different situations.
“He is a very adaptive driver, a natural driver and he has got plenty of experience with the team so that also helps. He has so many races under his belt in F1.
“He has been in tricky situations before and dealing with so many different setup issues at different tracks, which helps. I always thought he was good driver, so it just confirmed it this year, so no big surprises.”
