Jul.23 (GMM) Sebastien Buemi has admitted he is hoping to be selected to make his formula one debut with Toro Rosso in 2009.

The 19-year-old Swiss, a GP2 racer and F1 test driver for Red Bull, said after testing at Jerez on Tuesday that he sees Sebastian Vettel's graduation to the senior team next year as his chance to move out of the summit of the energy drink's junior development programme.

"For me my main objective is to try and finish well in the GP2 season this year, but then the objective is really to be in the Toro Rosso next season," he told the F1 website of British broadcaster ITV.

Buemi, seventh in the GP2 standings, was fifth quickest of the nine drivers in action at the Spanish F1 test on Tuesday.

He is well-placed to achieve Red Bull's support for the STR seat; reportedly the cream of the company's junior programme in the eyes of racing advisor Helmut Marko, and racing for Red Bull team boss Christian Horner's GP2 team Arden.

"If Red Bull is making a junior team then it is just not for fun," Buemi confirmed.

"They want to develop drivers and then when they get one who is not too bad they will put him in F1."
