With Sebastian Vettel heading to Suzuka for next weekend's Japanese Grand Prix where it's mathematically possible he could seal his fourth world championship with four races left to go in the 19-race season, the driver insists that the title is far from his mind and he's just enjoying each day - and each victory - as it comes.

"We're just focusing on continuing to take one step at a time and trying to get the best out of the car at every single race," he said after winning this weekend's Korean Grand Prix by a comfortable margin over the two lotus drivers of Kimi Raikkonen and Romain Grosjean.

But the fact remains that if he carried on his winning streak in the next race, and if Fernando Alonso fails to finish higher that ninth place in Japan, then the world championship will be done and dusted for 2013.

"I'm trying not to think about it to be honest, I'm trying to focus more on the present," he insisted. "There's still a chance for Fernando, I think, so we have to stay on top of our game.

"There are still a lot of points to get, even though it looks very good for us," he cautioned. "Even though it looks very good, it's still not over so we shouldn't feel too comfortable.

"I wouldn't write the championship off," he added. "Obviously there's still more points to get and we are currently in the lead. It's a very nice position and I am very happy, don't get me wrong, I wouldn't want to swap but anything can happen.

"The car is working... it's on the edge to be honest," he said. "More so than you would probably think from the outside. But it's obviously nice when you get the results like Singapore or this weekend."

Vettel is a big fan of Suzuka - both its history in the sport and the enthusiasm of the Japanese fans to turn out every year to support the event - and so clinching the title next weekend would be particularly sweet especially given that Vettel's victories this season have been plagued with booing from partisan crowds that has been uncomfortable for all concerned. No such worries about his reception next weekend however - assuming he's lucky enough to finish on the podium of course.

"Japan is one of the highlights in the year," he said. "I think it's the best track in the world, to be honest. The fans are crazy, completely crazy in a positive way so really looking forward to Japan. I think all of us who get massive support there, big fans of motorsport, passionate about F1 and I think they enjoy the whole weekend, so I'm very much looking forward to one of the highlights during the season."

An even bigger highlight if it comes with a title attached to it? "To be honest with you, I don't really care. I look forward to Japan because it's one of the nicest tracks of the whole season.

"Regarding the championship I think our target is to win the championship and not to win it in one place in particular," he continued to insist. "To be honest, I don't think it really matters. I think it's an exceptional situation anyway."

Right now it seems that the boy just wants to have fun and carry on enjoying what he's doing week-in and week-out on the track, where he's currently simply untouchable.

"I'm just loving what I do. The team is fantastic, I think we all have a good time and just enjoy the moment really," he said. "We're just having a good time. We enjoy the fact that the team is working very well."

And as far as Vettel is concerned, this more than all the aerodynamic intricacies and race strategies is the true reason for why Red Bull is riding so high at the moment. "If there's a secret, then it's that we are really enjoying what we are doing," he said.
