Stylist, entrepreneur and sports administrator, he is famous all over the world. The founder of clothing brand Diesel, Rosso is the chairman of OTB (Only The Brave), a holding company that controls a number of fashion labels, including Maison Martin Margiela, Marni and Viktor & Rolf. He has held several stakes in football over the years. From 1996 to 2018 he was the owner of Bassano Virtus, the local football team in Bassano del Grappa. Under his ownership, the side enjoyed the best results in their history, first winning the Serie D title before going close to promotion to the second tier on several occasions. In May 2018, he took over Vicenza Calcio, after the previous ownership filed for bankruptcy, and moved the headquarters of Bassano (which in turn was refounded as a separate entity from his ownership group) to the capital of the province, under the new name L.R. Vicenza Virtus.
