The former F1 driver also opened up on his son's upbringing, highlighting why he was so strict with him.
"I was hard for him, I was strict," he admitted. "But I think because of that, he is who he is, and I think he learned a lot from that, and he arrived here with a lot of confidence and he was not scared of anything. That's Max and that's what he needed."
Reflecting on a pivotal moment in Verstappen Jr's career, his father reminisced about the racer's debut for Red Bull, where he claimed his first F1 victory.
"That was something very special," he said. "He came to Red Bull for the first time and he won. It was so nerve-racking."
