Vettel not thinking about title

Sebastian Vettel says there is still a long way to go in the championship and that he is focusing on doing a "normal job" in Singapore.

Vettel holds a 112-point lead over his nearest rival Fernando Alonso with six races remaining, meaning he can wrap up the title this weekend if he wins and Alonso is lower than third, with neither Jenson Button nor Mark Webber second. However, Vettel insists he won't be focusing on the permutations and will just look to do the best job possible at the Marina Bay circuit.

"So far we haven't won anything," Vettel told reporters in Singapore. "We are in a good position but still have some way to go. We have to race and do our normal job, try to achieve our best. It is one of the most difficult tracks for cars and drivers; it is a long way to the chequered flag.

"Obviously a lot of people talk about it (the championship), but certain things have to happen. It reminds me of the situation we faced in Abu Dhabi last year, where people came up every two/three minutes giving another option, what is possible out of 1,467 options. This could be one, that is not the objective or target this weekend - the target is to optimise our performance."

Vettel said he was not going to lose sight of the overall aim, despite the potential to win the title so soon, and as a result was not feeling any extra pressure.

"Generally our target going into this season was to defend the title. We are in a very good position and there is no reason the target should change. It doesn't matter when, it matters that it happens.

"I think there is always pressure on me and us because we want to achieve our best every single weekend, and achieve our maximum. If there is a possibility or a chance to win we want to go for it. I don't feel any extra pressure trying to win the championship here or win it in one particular place. We just have to remind ourselves what the target was going into the season, it was not to win the championship in Singapore, it was to win the championship itself."
