Red Bull Racing's Sebastian Vettel has insisted there are no guarantees he will be able to win again this weekend in Abu Dhabi.

Vettel has dominated the second half of the season, winning every single race, en-route to securing his fourth F1 drivers' title - and helping Red Bull again claim the Constructors' - in India last time out.

Despite that run though, the German was keen to stress that he will need to work hard to make it seven wins on the trot on Sunday at the Yas Marina Circuit, even if he did concede he has a 'strong package'.

"I'm not getting in the car and thinking that there's a guarantee that we will do well," he said ahead of the 17th round in the 2013 F1 World Championship.

"Maybe that's a little bit the impression that you get from the outside. Obviously since the summer break we've won all the races but we come here and there's absolutely no guarantee that we will do well. We have to give it everything we have.

"Yes, we have a strong package so I think we have reason to be confident. [But] I need the team, I think the team needs Mark [Webber - my team-mate] and myself to push the car to the limit and to get some good results. There's no guarantee for what we've been doing the last couple of races to make it last."

Vettel also added that while both titles are now in the bag, there is still a lot to be gained in the final three grands prix, namely three possible victories.

"I don't think we approach this weekend as if there's nothing to gain. We love what we're doing. We enjoy the challenge and that's why there's no question as to why we are here and what we have to do. We want to race, race the others as hard as possible.

"If we have a chance, we want to win," he concluded.
