Guenther Steiner says he is not worried about Sauber's renewed partnership with Ferrari as he does not believe it will have any negative impact on Haas.
The American outfit has enjoyed a successful technical collaboration with the Scuderia since it entered Formula One at the start of 2016, securing an impressive eighth place finish in the constructors' standings in its debut campaign. 2017 has proven to be an even stronger season so far for Haas, with the team occupying seventh in the championship, having already matched the points total it achieved throughout the entirety of last year.
Sauber, like Haas, has been backed by Ferrari power, though the team has struggled this season with a one-year-old Ferrari power unit.
