Four-time world champion Sebastian Vettel will have to earn his place at Ferrari next year, according to team boss Maurizio Arrivabene.
The German has yet to challenge for the World Drivers' Championship since he joined the team, following a successful run at Red Bull.
Vettel is currently fifth in the standings but he has been criticised in the last few days following his performance at the Malaysian Grand Prix.
He caused a collision at the first corner and received a three-place grid penalty for this weekend, meaning his fourth-place finish in qualifying sees him start in seventh.
Despite showing some signs of potential, Arrivabene has admitted that the 29-year-old must earn a new contract in 2017.
He told the BBC: "Sebastian has a contract. We work together this year and next year. Then during next year we'll see.
"Each of us has goals. So it is only right that anyone, no matter who it is, earns their place and their salary."
