Haas team principal Guenther Steiner is certain that the team have learned from the mistakes of a difficult 2019 season.
Steiner says that his Haas team have worked on their areas of weakness in the off season after a year plagued with issues keeping the Pirelli tyres within their slim working window.
"I take things on board, and we are not going to make mistakes like last season. I can say definitely yes to that," said Steiner. "We have worked on that, understood that. There can still be mistakes.
"If I said we hadn't learned our lesson, that we were stupid like last year, that wouldn't make me feel great.
"No, we've learned our lesson. We're humble and we will try again like two years ago. Let's speak about two years ago."
Two years ago, Haas finished fifth in the constructors' standings, their best end of year position in the sport. While driver Romain Grosjean was noncommittal in his assessment of the improvements made in his post-testing interview, but Steiner was more upbeat about the developments.

"They are making the right noises," added Steiner. "A driver is never happy. To think what happened last year, they were very happy with it, and then it ended up not good.
"So everybody is very cautious. We are very cautious in our predictions for this season. We don't want to be saying 'It's all good', and then we fall hard.
"So we are doing a diligent job, we will try to do our best and we will see where it takes us.
"That happens every year. It's just that last year the developments didn't work."
