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.
Gutiérrez raced in Formula 1 with Sauber in 2013/14, and returned to a full-time seat with newcomers Haas after spending 2015 as Ferrari’s test and reserve driver.

"But I don't really blame them – I don't blame anybody – because I was the one to be too confident.”
Gutiérrez added that he has not completely abandoned hope of remaining involved with Formula 1.
"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.
I got to the point in F1 where I didn't have that in the short-term so that's why I decided to switch
