With just 70 days until the season start in Melbourne, Bottas has a lot of transitioning to do.
That is, if there's someone good enough to replace him.
Also, he doesn't care who replaces Rosberg.
Mercedes Petronas boss Toto Wolff says he had no knowledge of the recent F1 Champion's decision to retire.
Just days after his last race at Yas Marina, Formula One Champion Nico Rosberg has announced his retirement, effective immediately.
The 31 year old German decides to stay with Mercedes into 2018, without having to say a word.
