Felipe Massa says that Williams would be making a mistake in letting him go, with discussion over their drivers next year well underway.
Both Robert Kubica and Paul di Resta are being assessed, although Massa has been assured that he's still very much in contention.
But that doesn't seem quite good enough for the Brazilian, who firmly believes that Williams will suffer if they let him go.
"It's frustrating that the team is trying to go for a direction that can really be much worse than keeping the same," said Massa, as per Eurosport.
"If you see Lance [Stroll] is growing a lot, so to be honest I'm really doing a great job with my driving.
"I think the team has a direction that can just be positive to keep the way it is. If the team changes something, they can pay more than it costs to keep me! The team knows 100% what I am able to do."
Paddy Lowe, the chief technical officer, has confirmed to Massa that they're considering keeping him around, and while the driver trusts him, he worries that Lowe may not be making the decision.
"I really like Paddy, and Paddy knows what is better for the team. Maybe it's not 100% his decision, and they have to make a decision related to some other stuff.
"Unfortunately money is part of this game, unfortunately not in the right way, for the professional drivers, for the professional teams.
"That's why I think if Williams keep the direction they have now, they are behaving like a professional and top team. If not, they're thinking about different things."
Massa also believes his current position of 11th isn't a genuine one, with unfortunate incidents holding him back this season.
He added: "Where I am in the classification in the championship now is not because of my mistakes, it is because of things that happened in three races, that I lost maybe 30 points," he said, "The qualifying I'm just doing what I'm expected to do, and I'm really happy with my qualifying the whole season.
"If I had the right points that I'm supposed to have, I would have been maybe fighting very close to the Force India guys."
"I feel I am taking the best out of the car. I feel really comfortable driving this car. The car from this year for my driving style is a very good connection."
"The car from maybe the last three years, without the grip, just going sideways with the terrible tyres, is not a great pleasure, and maybe for my driving style I cannot give the best for different issues. Now I can, and maybe when you feel you are giving the best that you can give, then you are more motivated.
"So I still believe I can give, that's why I want to carry on."
