Guenther Steiner has hailed the impact Kevin Magnussen has had on Mick Schumacher's development since the Dane was recalled to Haas this season.
Magnussen replaced Nikita Mazepin ahead of the second F1 pre-season test in Bahrain 15 months after he and Romain Grosjean were released as Haas opted for an all-rookie line-up for 2021.
The Dane's return, coupled with a significant upturn in results courtesy of a much-improved car for this year, appears to have enhanced the mood within the garage.
Asked if Magnussen was acting as 'a teacher' to Schumacher, Steiner said: "Yeah, I would say so.
"As I always say, it is always good to have someone like him for Mick so he can take him as a reference.
"Even if Kevin is still young, he has done this for quite a long time now and he is very mature so he tries to help Mick out because he knows he is here to work for the team."
Magnussen "very fair" with Schumacher
Alongside Mazepin last year, Schumacher was unable to measure himself against a known talent.
Although Schumacher has yet to score a point compared to Magnussen's 15, Steiner believes the 23-year-old German has made noticeable progress which has been accelerated by Magnussen's arrival.
"It is a good position for Mick to be in to have somebody like Kevin who is very fair and gives him all the information," added Steiner.
"You can learn a lot yourself, but if you have got a teacher, it goes a lot quicker."
