Vettel says pressure is still on despite having wrapped up the title

The German clinched his second title in a row at Suzuka last weekend, while Red Bull looks set to secure the constructors' crown this weekend in Korea.

Vettel insists, however, that the team will not change its approach, and will be aiming to do the best possible job in all the remaining races.

"We love racing and the moment you come to a race thinking it doesn't matter where you finish is moment you stay at home," said Vettel. "The championship was the ultimate target. Reaching that before the end of the season is not the usual but nevertheless we come here with pressure.

"Even if people don't put pressure on us as usual, we put pressure on ourselves because we love racing. We will enjoy racing as usual but we will make sure that we do the best we can and we will not be happy knowing we can do better.

"The approach will remain the same. It was a tough venue for me last year. I was in good shape until 10 laps from the end, so obviously there is still something to be done. I've never been on podium here."

Vettel, who endured a difficult race in Japan as he struggled with the degradation of the softer tyres, says the team has been working to find some answers to the issue, and is hopeful things will be better in Korea.

"It is true that in other races we always had the luxury to go a lap longer or two but had to pit for strategy reasons, whereas in Suzuka we were the ones pulling into pits first," he said. "We were there quite early, earlier than we expected or we wanted.

"We suffered more degradation than we thought, so we have a couple of ideas. On Sunday everything turns out to be a little bit different, and the race is long so you have to look after the car and not only the tyres as well.

"We understand to some extent why the tyre wear was more excessive than we thought, but we need to come here and confirm it. We have a good chance to understand more about tyres, as the tyre approach this weekend is very, very aggressive, so not sure how many stops we will see, surely more than two, maybe five, we do not know yet."
