Sebastien Buemi admitted he was left with mixed emotions following the Brazilian Grand Prix despite scoring points for the first time since the Chinese Grand Prix back in April.

The Toro Rosso driver was in impressive form during the weekend at Interlagos and came close to setting his first quickest time in an F1 session in Friday practice before losing out to the Renault of Fernando Alonso in FP2.

Qualifying saw the Swiss driver impress as he picked up his best grid slot to date with the sixth quickest time while he then brought his car home seventh to give Toro Rosso its first point since an eighth place for the now departed Sebastien Bourdais in Monaco.

Despite that, Buemi admitted he was disappointed not to have scored more than two points after struggling for pace on race day and said he was looking to try and build on the result in the season finale in Abu Dhabi.

"It was a very difficult race for me, as I had to push hard every lap, but in the end to come away with points for the first time since China is a good result, for me and for the team, who did a good job today," he said. "My start was difficult, as I was sandwiched between Kubica and Rosberg at the first corner, so they got past me, which was a shame. However, we did not have a particularly strong race pace, so we must look at the data to try and understand why.

"I have mixed feelings because after our performance on Friday I had hoped to finish in the top five, so although the points are nice, it's not as good as I expected. Now we can look forward to Abu Dhabi where we must try and build on this result and keep moving forward."
