The 19-year-old from Monaco is currently dominating the Formula 2 series, and thanks to his ties to Ferrari is being linked with a move into F1 next year.
Some reports say a Haas or Sauber drive could be on the cards, but Leclerc said in Hungary that he is “calm” in the face of the speculation.
“In my career I have always taken it step by step, so now I am trying to win the Formula 2 title and then I would like to go to F1,” he told Italy’s Corriere della Sera newspaper.
Asked if, as a F1 team boss, he would sign him up for 2018, Leclerc answered: “I would, because I feel ready.
“Would I be willing to wait another year? I would prefer no, because if I win the F2 championship I cannot defend the title, so waiting would not help me.”
The Sauber rumours have taken a big step forward in recent days, with the Swiss team cancelling its 2018 Honda deal and signing up with Ferrari instead.
Leclerc said: “The big dream is to wear red and I hope that one day it will become reality. But I also think of everything, as long as it is F1.”
