Buemi - Malaysia will be tough fo Toro Rosso

F1's only 2009 rookie Sebastien Buemi has admitted he does not really expect to break out of the bottom-five qualifiers when the action resumes in Malaysia this weekend.

On his Melbourne debut, the 20-year-old Swiss out-qualified the more experienced Sebastien Bourdais, and stayed in front of his French team-mate in the race to score points.

But having qualified 16thh in Australia, Buemi told the Le Matin newspaper that he is expecting another difficult weekend for round two.

"I know that the Malaysian Grand Prix is not going to suit our team, it is a very different circuit to Melbourne," said Buemi after jogging the Sepang layout twice to acclimatise to the heat and humidity.

"We are waiting to get some new parts for the car and will have to see what effect they have. The goal is to get through to Q2, to be in the top 15, but the competition is very tough," he added.
