Pascal Wehrlein has said that his chances of staying in Formula 1 next year are now "quite good".
The Mercedes-backed German previously seemed resigned to losing his place at Sauber, as the Swiss team ramps up its relationship with Ferrari.
"There is still nothing new," Wehrlein told reporters in Malaysia. "But I think there will be a decision in the next few weeks. This year we will not have to wait as long as last year."
When asked if he is now more positive than a few weeks ago about his prospects for 2018, he answered: "I think the chances are quite good. But during the season I try to only think about the coming races.
"Of course I will always be informed when there are new developments. Toto [Wolff] tells me of any important phone calls and of course I always talk with Fred [Vasseur].
"I'm assuming I'll be in Formula 1 next year."
