Esteban Gutiérrez has admitted he was “too confident” that he would remain in Formula 1 with Haas this year, before he ultimately lost his seat to Kevin Magnussen.

"I never close doors," he said. "Never, never. I really love Formula 1.
"I always want to see a way that I can grow, that there is commitment both from the team and the driver and let's say, a path I can really make steps forward.
