A 2021 Ferrari race seat for Mick Schumacher would be "too early" for the F1 legend's son.
That is the claim of team boss Mattia Binotto, even though 20-year-old Schumacher has already tested a 2019 Ferrari and is a member of Maranello's driver academy.
Schumacher, whose father is seven-time world champion and former Ferrari driver Michael Schumacher, will also contest his second season of Formula 2 next year.
He finished twelfth overall in 2019.
"Will he be a good candidate for Ferrari?" Binotto said at an end-of-season meeting with journalists.
"It's really too early to say that.
"For 2021 it will be important to have drivers with experience, because the cars will be completely new.
"But I am pretty sure that he is a good candidate for Formula 1," he added.
Binotto said 2020 will be an important year for Schumacher in 2020, announcing: "We expect a lot from him next year."
