Team boss Franz Tost let the cat out of the bag when we spoke on Friday, albeit in the context of a slightly negative remark about his drivers.
The gist of it was that Toro Rosso has essentially had a good season and had scored some points, but there had been too many mistakes from the young drivers. When they both come back next year, Tost explained, Buemi and Alguersuari will be expected to deliver, drive fast and not crash.
