Sebastien Buemi insists he's not at all concerned about rumours that Daniel Ricciardo could take his Toro Rosso race-seat next season.
With Red Bull advisor Helmut Marko revealing Ricciardo is the most likely replacement for Mark Webber when he steps down, the team is keen to give the 22-year-old experience in lower ranked teams.
Already they have signed a deal with HRT that saw Ricciardo made his F1 debut at the British GP as Narain Karthikeyan's replacement.
Rumours, though, claim after his spate with HRT, Ricciardo is set to move to Toro Rosso next season.
And although it is not yet known if he will replace Buemi or his team-mate Jaime Alguersuari, the Swiss driver is confident he does not need to look elsewhere as he has a deal with Red Bull.
"I have a contract with Red Bull until 2013, so it's not my decision to make contact with other teams," Buemi told Spanish daily AS.
