George Russell

Team: Williams
Age: 20 (21 on debut)
Experience: Rookie
Race Number: #63
Formula 2's 2018 winner beat out the likes of Esteban Ocon and Sergey Sirotkin for this seat. George Russell fully deserves his great reputation. Russell has shown excellent speed and consistency in his victorious campaign, beating both Norris and Albon to the title.
He's currently a Mercedes youngster and his style is reminiscing of the last Brit to drive for Williams. Jenson Button - the 2009 World Champion - was smooth and consistent from an early age and impressed during his rookie year.
JB was demoted to Benetton for 2001, but expect to only see this young man going further up. He's got the backing of the best team in the sport and has already shown that he's quick in modern F1 cars, setting the unofficial lap record at the Hungaroring in testing. He'll need to do well to beat his teammate, though.
