The Finn is on a one-year contract with Mercedes, and is up against a monumental adversary in the person of Lewis Hamilton, but Lauda is providing as much guidance as possible to the Silver Arrows new recruit.
"Valtteri Bottas is pushing hard to be ready for the 2017 season," the Austrian F1 legend told Swiss newpaper Blick.
The triple-world champion says that year-to-date, he has been impressed with the Finn's general attitude and approach while settling in with his new team.
"I'm always on the phone with Bottas. He wants to know everything, which is motivating me as well. He is getting full support from all of us."
On the subject of Mercedes' 2017 car, Lauda has seen the broad lines of the team's W08 challenger, and expressed his enthusiasm with the shape of things to come, believing that everyone will be happy with what they see when the car is unveiled on February 23.
"The fans will surely like what they see," he concluded.
