Steve Jones presents highlights of the Russian Grand Prix - the fourth race of the 2016 season. It is the third time Formula 1 has visited the Sochi circuit on the Black Sea coast and it has been a happy hunting ground for Mercedes' driver Lewis Hamilton who will be hoping to make it three wins out of three. But it is teammate Nico Rosberg who is smashing it in 2016: he's won all three races this season, and the last six in total. In Shanghai, following a gearbox change penalty and a mechanical failure in qualifying, Lewis fought from the back of the grid to seventh, limiting the points-damage. But he needs to keep out of trouble and start challenging Nico if he is to keep his championship hopes alive. Will the fact that he is the only driver ever to have won at the Sochi Autodrom give him confidence? And can Ferrari and Red Bull continue to challenge Mercedes' supremacy?
