Valtteri Bottas is determined to stake his championship claim once again at the Azerbaijan Grand Prix, having been knocked off the top of the standings by Mercedes team-mate Lewis Hamilton. Bottas is also out for vengeance on the Baku circuit, after a near-miss 12 months ago.
The Finn was cruising to a victory that would have put him top of the drivers' standings in Azerbaijan last year, only to run through a piece of debris three laps from the end, causing a puncture which ruined his race.
Bottas' season unravelled from there as he dropped out of title contention and had to play second fiddle to Hamilton.
However, having led the championship for the first time in his career after this year's races in Australia and Bahrain, Bottas has a taste for top spot.
"I'm just disappointed I didn't win [in China] because obviously when you start from pole there's only one goal for the race," Bottas said.
"I know myself, but it was all about the start, so that's why it was disappointing.
"It's a sport that is all about details and about learning those and seeing if anything can be better in the future.
"Sometimes there are things that you can't affect, maybe [China] was one of them, but we need to make sure if there's anything we can learn.
