Valtteri Bottas has played down suggestions his job description is fundamentally changing for 2017.
Ever since debuting for Williams in 2013, the Finn has had a more experienced teammate, most recently the Ferrari veteran Felipe Massa.
But Massa is being replaced by teenager Lance Stroll for 2017; the second-youngest rookie in F1 history.
Some think Bottas will necessarily be the Williams ’team leader’, but the 27-year-old insisted: "My job doesn’t change in any way.
"My job is to get the most I can out of the car and the team," he is quoted by Turun Sanomat newspaper.
"Outside the car, then of course I am ready to help Lance if it is needed. But Lance is a young and skilful driver who will definitely learn quickly," Bottas added.
