Toro Rosso will not select from outside of Red Bull's own talent pool for its 2012 driver lineup, team boss Franz Tost has confirmed.
It is believed Sebastien Buemi, Jaime Alguersuari, and young Red Bull hopefuls Daniel Ricciardo and Jean-Eric Vergne, are all in the running for the Faenza based team's two race seats next year.
"It is 100 per cent certain that next year we will have two Red Bull drivers," Austrian Tost told the Sportwoche publication.
"That is the meaning and the purpose of why Red Bull bought the team," he added.
"Our job is to allow young drivers from the Red Bull pool to enter Formula One in training for (the move to) Red Bull Racing," said Tost.
Since the Minardi takeover in 2006, however, the only driver to successfully move from Toro Rosso to the premier team is Sebastian Vettel.
"The reasons for that are simple," said Tost. "First, he is more talented than the others.
"He is also more disciplined, brings more passion for the sport, is more innovative, open and more flexible in accepting suggestions to make himself better. And that's why he's the world champion," he added.
In Formula One you have to live Formula One
"In their development too many drivers get to Formula One and think 'Now I have made it'. Actually, the hard work has only just begun. Everything before is kindergarten.
"In Formula One you have to live Formula One, 100 per cent, yet only a few do that completely," said Tost.
