Detlev Höhne, Chairman of the Supervisory Board of FSV Mainz 05, has criticised the ever-increasing influence of investors and companies on sporting competition in the Bundesliga. “Wolfsburg and Leverkusen – a minus in the end is simply compensated by the Group,” the official said in an interview with the “Bild”. Höhne sees such practices as a erosion of the so-called 50+1 rule, according to which a donor in Germany may not hold more than 49 percent of the shares of a football club.
