2018 F1 Season

Taken from PlanetF1:

“Valtteri knows exactly where he needs to be next year,” said Wolff via Motorsport.com.
“He needs to have all the bad luck gone and perform on a level with Lewis.
“That is what is needed for the 2020 year. He knows very well that, and he has that in him.”

No pressure at all, just need to perform on the same level as the 5 time world champion and the best driver on the grid. If Bottas has a slow start to the year I wouldn't be surprised if that seat is given to Ocon rather quickly, even mid season.

Edit: Bottas' main sponsor, Wihuri, stopped sponsoring Bottas and said it was because of disappointing results. Wihuri played a big part on getting him to that Mercedes seat. You can see the countdown has started unless Bottas is really good starting the next season.
