Bortoleto gets advice from ex-Sauber driver Bottas: 'It won't be easy'

When rumours around the second seat at Sauber (soon-to-become Audi) were brought up, two names were usually considered to be in the running: Gabriel Bortoleto and Valtteri Bottas. In the end, the young Brazilian was chosen by Swiss team, and he will replace the Finn next season. Bottas was asked about what advice would he give for the next Sauber driver.
