Valtteri Bottas recorded the fastest time of testing yesterday in Barcelona. Bottas, embarking on his debut season with Mercedes after taking over from retired world champion Nico Rosberg, bettered his previous best time from last week by nearly four-tenths of a second as Mercedes reasserted their dominance at the top of the timesheets.

"We're definitely making good progress as a team and I'm feeling more and more comfortable in the car every time I go out on track," said Bottas.
He continued, "There's still plenty of work to do so we need to maximise the next two days of testing.
"Fastest laps don't matter in testing. What matters is where you are when you get to Melbourne (season-opener on March 26)."
