Despite a degree of mystery surrounding Lewis Hamilton's sudden slump in form at the Russian Grand Prix, Valtteri Bottas says he understands the reasons why he had the edge over his Mercedes teammate in Sochi.
Bottas took the first win of his career in Russia after a breakthrough weekend in which he qualified nearly 0.5s quicker than Hamilton and finished the race over 36 seconds ahead of the 44 Mercedes. Ahead of this weekend's Spanish Grand Prix, the team admitted there was no quick fix for Hamilton's issues while Bottas is confident his upturn in form was not just related to his historically strong form in Russia.
