ABU DHABI, UAE - Seven months into the job and Ferrari team bos Marco Mattiacci is apparently about to lose it.Germany's Sport Bild on Saturday (Nov 22) cited "well-informed sources" in claiming the 43-year-old Roman is to be replaced by Marlboro Europe brand manager Maurizio Arrivabene.Mattiacci only took over from Stefano Domenicali in April 2014. He said on Friday (Nov 21) that what had struck him most about Formula 1 since switching from heading Ferrari's North American road car arm was "the intensity, the complexity, the incredible amount of talented people that are in F1".GLOBAL PLATFORMMattiacci said: "How amazing is this sport, a global platform, the visibility that specifically in my case I don't like for myself, but which is a consequence of the job."The level of competition, (the) aggression is really high, so a lot to learn, but at the same time I think I brought an understanding of people, choosing the right people and from here how to create an organisation for the future."Mattiacci has overseen the replacement of the departing Fernando Alonso with Sebastian Vettel but, according to Sport Bild, the Italian is about to vacate his post."Supposedly," said correspondents Ralf Bach and Bianca Garloff, "Sergio Marchionne was not satisfied with the Roman's work."Mattiacci's successor, Arrivabene, is no stranger to F1, having overseen Marlboro's sponsorship of the Ferrari team and reportedly already close to Bernie Ecclestone.
