Guenther Steiner has insisted there will come a time where Haas rookies Mick Schumacher and Nikita Mazepin "realise how little they knew" when they started in F1.
Schumacher and Mazepin have grown into their debut campaigns having moved up from F2 over the winter, with the Russian initially struggling to make an impact with error-strewn races leaving him firmly at the back.
After strong showings in Monaco and Azerbaijan, Haas jumped Williams for ninth in the championship and with such progression already, Steiner expects his drivers to realise the amount they have learned so far.
"There is always room for improvement, as you know with all of us," said Steiner.
"They are improving and as I always said from the beginning of the year, at some stage, they will actually realise how little they knew in F1 when they started in Bahrain this year.
"I don't know when that is coming but there is normally a moment when you get to it where you are learning when you are young because for sure, in Bahrain, they thought they know it all and then races later they think wow, how little did I know."
Haas rookies disadvantaged by lack of experienced team-mate
Schumacher and Mazepin have had to work hard for every gain this year without an experienced team-mate to assist them with their development and the lack of representative data to study.
"There are surprises that mean the more you learn in the races because you just realise how different it is," Steiner added.
"They have made good progress, there is always room to improve and they have still got a bit of a way to go.
"Both have got a little bit of a disadvantage that they have nobody to... no experience to judge against and it makes their learning tougher but you learn more."
