Toro Rosso's current drivers are still unsure if they will be racing beyond the 2011 season.
Team owner Red Bull's driver manager Dr Helmut Marko is famous for the pressure he puts on contracted drivers.
And hanging over Jaime Alguersuari and Sebastien Buemi's heads at present are the advancing careers of Marko's latest favourites Daniel Ricciardo and Jean-Eric Vergne.
"We have not talked about the future or next year's contract," Spaniard Alguersuari told the EFE news agency at the weekend.
"It is very important that the whole team is focused on the rest of this year," he added, referring to Toro Rosso's push to beat Sauber to seventh in the constructors' world championship.
According to veteran Blick correspondent Roger Benoit, Swiss Buemi is in exactly the same situation with "five penalty shots" yet to kick in Japan, Korea, India, Abu Dhabi and Brazil.
"I know it's going to get harder and harder up to the finale in Sao Paulo but I can live with the pressure, and my morale is intact," the 22-year-old, who trails his teammate Alguersuari by 3 points, said.
He confirmed that Toro Rosso is pushing hard to beat Sauber.
We have a different car now; front and rear, everything has changed
"We have a different car now; front and rear, everything has changed," said Buemi before his flight to Tokyo.
Australian Ricciardo, meanwhile, is currently at HRT but tipped to move to Toro Rosso in 2012.
But "All this is rumour," he insisted to the Press Trust of India at the weekend.
