HIGHLIGHTS: See all the action from the opening practice session for the Russian GP

Formula 1 returns to Russia this weekend for round 15 of the season, with the title battle between Lewis Hamilton and Max Verstappen still finely poised – just five points separating the two contenders.

The drivers got their first taste of the track on Friday morning with the first practice session, and it was Sochi specialist Valtteri Bottas – who has two wins here – who went quickest ahead of his Mercedes team mate Hamilton.

Verstappen – who is carrying a three place grid penalty at this race after the stewards judged him to be "predominantly to blame" for his collision with Hamilton at Monza – was third fastest ahead of Ferrari's Charles Leclerc.
