Sebastian Vettel isn't giving up on winning the F1 drivers' title this year, even though he lost more ground to Brawn Grand's Prix Jenson Button and Rubens Barrichello on Sunday at Monza.

Vettel struggled during the Italian Grand Prix and in the end was fortunate to get a single point, one of a number of runners to benefit on the final lap when Lewis Hamilton crashed out whilst running in third.

Despite finishing eighth though, the German now lies 26 points behind Button, and with only four races left and a maximum 40 points up for grabs, he may have a mathematical chance of overhauling the Englishman, but realistically it is not looking very promising. Indeed this is even more so when you factor in the fact he has very few engines left.

However, Vettel is trying to stay positive and is hopeful that his Red Bull RB5 will be more competitive in Singapore in two weeks time.

"I think we had a good start and a good first lap, but then I was struggling to stay with the cars in front. The biggest issue today was the first five to ten laps when I was struggling with low grip, I was sliding a lot and lost a lot of time. Overall, we didn't have the speed and perhaps this wasn't the best track for our car," Vettel pondered.

"For the next race we will put more downforce in again and maybe we'll be better, we will see. The Championship isn't over - our target is to do our best, we're here to win races and the Championship, so we have to focus on that, all the rest is out of our hands."

Red Bull Racing team boss, Christian Horner, meanwhile wasn't at all happy and with Brawn GP extending its lead in the constructors' championship to 40.5 points it isn't looking much better on that front either.

"We were lucky to pick up one point following Hamilton's accident," Horner added. "Unfortunately we just weren't quick enough today - it's been our worst performance of the year at a track which has exposed some of our weaknesses. Hopefully the remaining circuits will come back more in our favour."

"What a disappointing result," added Fabrice Lom, Renault's principal track support engineer with RBR. "To get only one point and have a retirement [with Mark Webber in the sister car] is very bad for us.

"Brawn scored a one-two finish, so congratulations to them - but our result is hard to swallow. It's going to be very difficult in both titles for us, but we won't give up - we still have four races in which we can fight."
