Sebastian Vettel is fighting with Lewis Hamilton to become the first driver of the current generation to achieve five World Championships.
Vettel has claimed that winning the title in the Ferrari, as his childhood idol Michael Schumacher did, would be the “ultimate satisfaction”.
The German said: “After you’ve won a little bit it becomes a bit special to win against the best.
“Now I am searching for the ultimate satisfaction to win with Ferrari, which is the greatest team in history.
“That’s my ultimate target now - win for Ferrari and win against the best, which arguably Lewis is one of them.
“It’s a long season. If it’s one race that’s a different story, but there are lots of races.
“Based on winter testing, I would say we are in good shape and could be in better shape but it’s always like that.
“Certainly, if it didn't happen then you would start to realise, but now I don’t see the point of thinking ‘what if?’”
If either Lewis or Sebastian win this year's title, they will go level with Juan Manuel Fangio’s record of five titles, only surpassed by Schumacher.
Vettel said: “I think nowadays the times are different, they are very different times to what Fangio achieved.
“Every era has its own challenges, certainty they were different back then. It’s not in my mind now.”
