Maybe because in 🇩🇪&🇮🇹(I' m 🇮🇹) for many many years singing anthem was a tabou..it meant u were fascist/nazi In 1999 🇮🇹 President asked players and people to sing it And it became A TRUE ANTHEM OF BATTLE...VERY IMPORTANT, 4 EXAMPLE last year when we won European championship and in 2006 world ch..ship In 🇩🇪 this tabou goes on Even 77 years after nazi/fascism has been won
