The good news for Bottas is that Mercedes seems to want to keep him.
"I'm really satisfied with Valtteri," boss Toto Wolff told the Finnish broadcaster C More at Silverstone.
Asked about Bottas and Mercedes for 2018, he added: "I think looking at his performance, it really is a no brainer.
"But it's not just about next year but also the years after. We have to put all the puzzle pieces together.
"After the race in Budapest I will think about it some more on the beach," Wolff smiled.
Wolff's reference to the years after 2018 is an indication that Mercedes could make a move for Sebastian Vettel, Daniel Ricciardo, Fernando Alonso or another top driver for 2019 and beyond.
As for Bottas in 2018, Wolff said: "I think yes, we are 90 per cent ready."
