The lowdown on Valtteri Bottas
Lee McKenzie's view
"Valtteri Bottas is another typical Finnish driver - he doesn't give much away and is not big on emotion.
"When he and Kimi get alongside each other it normally ends with one crashing off as neither of them will give up.
"Valterri is a really talented driver managed by Toto Wolff and Mika Hakkinen and this season he may just have the car to match his talents as he joins Mercedes as a replacement for Nico Rosberg.
"He trains super-hard, I once saw him running in Abu Dhabi in the midday baking sun.
"On a personal note, he got married last season to his girlfriend Emilia, who is also an Olympic swimmer for Finland."
F1’s latest flying Finn is cool, calm, collected, fearlessly competitive and ultra fast. He may need all of those qualities as he steps up to Mercedes in 2017.
A product of Williams’ driver development programme, Bottas won the 2011 GP3 title before signing as Williams’ reserve driver for 2012.
He served dutifully, impressing enough in his limited practice runs to snatch Bruno Senna’s race seat for the following season.
Bottas’ maiden year in F1 was tough, with Williams suffering a miserable campaign, but he kept the faith, scoring his first points late in the season.
With Mercedes power, the Williams team was resurgent in 2014 and Bottas capitalised on the speed of his mount, scoring six podium finishes and generally outclassing his more experienced opponent.
He climbed the podium twice in 2015, and earned Williams only podium last season in Canada. Now he has set his sights on more, targeting his first grand prix win with the Silver Arrows.
