As Williams narrows its driver choice for 2017, Felipe Massa says he has received support from people within the team who "understand racing".
The Grove-based outfit is considering the Brazilian for a fifth season but is also evaluation other options which include Paul di Resta and Robert Kubica.
Massa, who retired at the end of last season before changing his mind when Valtteri Bottas moved to Mercedes, wants a decision on his future by his home race in Brazil and claims that Williams' engineering staff would like to see the 36-year-old race on.
"To be honest, we are discussing with the team, and the team knows 100 percent my points to stay another year," Massa said.
"I was always a professional driver, and I stay and I will finish as a professional driver, like I started my career. And that's the most important thing for me. The team knows what I can give to the team.
"I would say definitely I have all the people that understand about motor racing on my side inside the team – engineers and everything. That's what counts for me.
"Then you have some other decisions which are not depending on the talent of the driver, or what you can give to the team on the driving point of view. This is not up to me to say anything."
Massa acknowledged that the final decision resides with the team's top brass and not those who work on the factory floor.
"The people in the management, they have their own way to decide, which hopefully is in the right direction as a top team, a good team."
"I know what I give, I'm totally motivated to carry on another year. I'm staying if the team really wants to have me as a professional side, like I've always been in my career.
"That's the most important thing for me. And I'm quite relaxed. If I stay here next year, I'm sure I will do the best I can to give the best to the team, like I did a lot.
"But if not I'm relaxed to find the different way of my life as well. For sure I will not wait until December.
"I don't put a timeline, but I hope it will be in the next weeks. I don't want to arrive maybe in the last two races not knowing about my future. We'll wait and see what's going to be the decision, and I hope it will be soon."
