Sebastian Vettel has admitted that it's too soon to say whether teammate Charles Leclerc is the best that the German has ever driven with. The 32-year-old made his debut in the sport in 2007 and has driven with several high calibre names in his time.
Vettel is locked in an interesting battle with the 22-year-old who currently holds a nine-point advantage going into the final four races of the season.
"I do not think it's fair, it's still a little too early. Certainly, but obviously, he is still a little too young. But it is very fast and I do not think anyone doubts it, "Vettel told Motorsport.
"In the end, you can not really compare, because you would need to put Mark, Kimi, Daniel and Vitantonio in the same car at the same time for it to be correct."
The battle between the two will commence this weekend as racing moves to Mexico.
