Kevin Magnussen is remaining cool despite a career-best season, which included a ninth place in the standings and 56 points.
The Haas driver didn’t achieve a podium but he was one of the best of the rest but the Dane was not satisfied with this.
"I do not rate such a season," he said to Motosport-Total.com.
"I won nothing - in my first year, after all, I got a podium, which is much more important than the result this season."
"It's the best team I've been in Formula 1 so far.
"With my experience, it's even more fun to start in Formula One."
Despite remaining modest about his achievements Magnussen did reveal finishing fifth would be disappointing in 2019 after challenging for fourth this year.
"That would be a disappointment because we fought for fourth place all year round.
"But we still have room for improvement and can continue to improve," said Magnussen.
"We do not set a firm goal, it's difficult to predict what's going to happen next season, and we want to continue to grow and leverage the experience we've gained."
