Lewis Hamilton says there is "still a long way to go" in the Formula 1 title race despite moving to the brink of triumph with victory in Russia.
He needs to beat Ferrari's Sebastian Vettel by nine points and his Mercedes team-mate Nico Rosberg by two in the US on 25 October to seal a third title.
Hamilton dominated in Russia following Rosberg's retirement early on with a throttle problem, the German having converted pole position into a lead on the first lap.
Rosberg's retirement meant he slipped back to third place in the championship, seven points behind Vettel. But he refused to concede his chances were over.
