With six races left in the 2018 Formula 1 season, Lewis Hamilton (Mercedes) looks close to clinching his fifth driver's championship.
If he were to win, the Briton, who leads the closest competitor Sebastian Vettel (Ferrari) by 40 points, would match Argentine driver Juan Manuel Fangio, who won five championships from 1951-1957.
Hamilton took the crown in 2008, 2014, 2015 and 2017.
When the season ends Nov. 25 with the Abu Dhabi Grand Prix, Hamilton hopes to have won a sixth championship, which would place him near legendary driver Michael Schumacher, seven-time world champion.
Schumacher's compatriot Vettel, also with four titles to his credit, is likewise seeking to go down in history as one of the world's greatest drivers.
The focus at Sunday's Russian Grand Prix in Sochi will once again be the Hamilton-Vettel - and therefore the Mercedes-Ferrari - duel.
With four wins in the last five races, the English driver seems confident of clinching his fifth championship.
Even though Hamilton has a "healthy advantage," Mercedes team director Toto Wolff said that "there is still a long way to go."
In the next two months, racing activities will move from Russia to Abu Dhabi, with several stops in Japan, the United States, Mexico and Brazil.
"We showed an excellent performance in Singapore and the victory was a fantastic reward for all the hard work that had gone into it," Wolff said this week.
"But it also reinforced another point: there are no easy wins this season," the team director added.
"We have to fight hard for every bit of performance in order to have a chance to fight for victories. This fight will continue in Russia," he said.
A Mercedes driver has won each of the four previous GP races in Russia: Hamilton (2014, 2015), Nico Rosberg (2016) and Valtteri Bottas (2017).
