The Ferrari president, Luca di Montezemolo, has warned Felipe Massa he will need to improve next year if he is to remain with the Scuderia.
The driver heads into the season's final race in Brazil this weekend trailing team-mate Fernando Alonso by 137 points and without a podium finish.
Di Montezemolo said: "Let's hope he can finish with a good result in Brazil. He'll have to prove himself next season."Reuse content
