Sebastien Buemi's place at Toro Rosso appears safe for now.
After teammate Jaime Alguersuari put in a string of good results, reports suggested Swiss Buemi, 22, is now most in danger of losing his full-time seat to Daniel Ricciardo in 2012.
But Blick newspaper quotes Red Bull's driver manager Dr Helmut Marko as saying: "Buemi is definitely better than his current results."
The Swiss publication also quoted Buemi as expressing confidence in himself.
"I have confidence with the car, I'm fast -- but luck is sometimes just not with you. Eventually it will come back to me," he said.
Meanwhile, Buemi has celebrated with his grandfather Georges Gachnang, who has restored the Cooper Monaco in which he contested Le Mans in 1960.
"Without his passion, I would not have become a racing driver," he said.
