"For me, that someone like Prost says that about me, you can imagine how that makes me feel. He is one of the most important people in formula one -- for me, he was on the same level as Ayrton Senna.
"Three or four years ago I would not have imagined someone saying something like that about me, so it means I have to keep doing things just as I have done," Sainz is quoted by the Spanish press.

Sainz Jr agrees: "I'll talk about 2018 when I'm finished 2017. Right now, without having done the first race, to think this is the year for me to make the leap is to take energy from one place and put it somewhere else.
"All my energy is on Melbourne, then China, then Bahrain. Race by race, and then we'll see where we will be," he added.
