I worry that she doesn't have a great deal of top flight experience in men's football. I read that she is in the pool of referees for Ligue 1 this coming season, so she will get that experience in time, and so maybe next year's Super Cup may have been a better appointment. Bibiana Steinhaus, having done a full season in the Bundesliga, may have been a better choice for this particular match.
That said, I think it's great that women are getting opportunities in men's football - and I really hope it goes well for Stephanie and her team.
