What a difference a year makes.
In 2018, Valtteri Bottas left Melbourne after the opening race of the season on the back foot.
He had a big crash in qualifying, started well down the grid, and just about managed to salvage a few points with eighth place. His team-mate Lewis Hamilton took pole by more than half a second and only lost the win due to a Mercedes strategy error.
Fast forward 12 months, and Bottas has sent a convincing message of intent for the remaining 20 grands prix with a resounding victory.
