Red Bull signed the youngster mid-way through his first season of car racing, announcing him as a Formula One driver for 2015 less than a week later.
He was only 17 when he made his Formula One début in Australia last year, and many questioned whether he was ready for F1.
"We were right to sign him and put him into Formula One at an age where everybody called us mad," Marko told the official F1 website. "And that he has proved ever since that he is something special."
Little over a season later, he'd gained promotion to Red Bull racing and won his first race.
"Yes, he’s shown on many occasions that he is light years away from your common Formula One driver by winning his first race sitting in a Red Bull. Yes, the two Mercedes drivers took each other out so this win probably fell in our laps, but Brazil showed that he is not only above average but that he will be a great one."
