When it comes to Formula 1 drivers, Mercedes has rather an abundance of riches. Not only does it have a newly-minted four-time Formula 1 world champion in the shape of Lewis Hamilton, it also has Valtteri Bottas, currently closing in on second in the 2017 points standings, Esteban Ocon, getting better with each race at Force India, and Pascal Wehrlein, still Sauber's sole points scorer this year.
But Mercedes is about to have a driver problem - albeit a good one - thanks to the performances of another star on its books: up-and-coming Briton George Russell. He has just won the 2017 GP3 title and will make his grand prix weekend debut in Brazil on Friday.
Russell, 19 years old and from Kings Lynn, has scored four wins, three poles and set five fastest laps in GP3 so far in 2017, and he wrapped up the F1-supporting third-tier category with one round to spare at Jerez last month. The 2014 McLaren Autosport BRDC Award winner did so against highly-rated team-mate opposition in the form of Renault-backed Jack Aitken and Honda junior Nirei Fukuzumi at the ART Grand Prix squad.
