Sainz remains humble after Renault's highest place finish since return

Carlos Sainz says he still has a "a lot of work" to get the most out of Renault's 2018 F1 car, despite scoring the best result since the return of the works outfit in 2016.

Sainz finished fifth in Azerbaijan, beating the team's previous best of the current era of sixth. Despite outperforming teammate Nico Hulkenberg, the Spaniard insits he or the car have not yet reached their limit.

"I know there's still a lot of work to do," he said.

"Especially to extract the last two tenths of the car in qualifying, like Nico is doing.

"I feel in the race I am a lot closer, but you know, if I can still do P5 without having 100 percent confidence in the car, it just means that when I get that little 5-10 percent more confidence that I need on the car, I will just be on top of it."
