Felipe Massa has said that he is not convinced that privatisation is the answer as Interlagos looks to safeguard the future of the Brazilian Grand Prix.

While Nico Rosberg has a chance to seal the 2016 title at Interlagos this weekend, the future of the race in Sao Paulo is in doubt, after Bernie Ecclestone and the FIA published the 2017 calendar with an asterisk for Brazil.

Recent reports have suggested the brand new mayor of Sao Paulo, Joao Doria, wants to privatise the Interlagos track, which has hosted F1 since 1990.

"I'd like to talk to the mayor," said Massa, who will contest his last home race in Sao Paulo, his native city, this weekend before retiring.

"I want to hear his ideas before responding about something I don't know about. If the privatisation happens for the good of the circuit, I am completely in favour," he told Brazilian journalists in a pre-weekend dinner.

"If the privatisation is for something else, as happened to the track in Rio de Janeiro, then I am not in favour."

Massa, 35, also admitted that he is worried about the future of Brazilian drivers in F1, with only Felipe Nasr left to carry the banner beyond 2016.

Yet there is a chance there will be no Brazilians on the grid at all next year.

"I hope that does not happen but there is a possibility," said Massa, "because Felipe has not signed a contract."

The 2016 championship concludes on November 27 with the Abu Dhabi Grand Prix.
