The Brazilian's future remains in doubt, after Marcus Ericsson was confirmed at the team and Nasr's backing sponsor Banco do Brasil pulled out from Sauber.
"I feel like I did everything I could to deserve a place," Nasr said.
"I have been able to deliver the results that I think Formula 1 is looking for. When the opportunity came I was there to take it, there to take points for the team.
Felipe Nasr out-scored Marcus Ericsson in their two years together, and Nasr's two points at Brazil this year meant they finished ahead of Manor.
"In my first year I scored 27 points for the team, which put us ahead of McLaren last year. This year even with all the difficulties we faced, every time I had an opportunity in the race to take it we came very close to [scoring points], and in Brazil, we did it.
"Just putting in a balance over two years, I was there to deliver what the teams are looking for. So obviously I would be pretty disappointed if we're not here next year."
