Support A 2011 survey has shown that CFR Cluj has the fourth-largest number of supporters in Romania. They have many fans in Cluj-Napoca, but also in some other parts of the country. Since the 2014 withdraw of important groups such as "Patriots" and "Commando Gruia", the fans have a single big group called "Peluza Vișinie", which consists of former members of older groups such as "Romaniacs", "Juvenes", "Gruppo Gara", "Valacchi", "Pride 1907", "Nostra Famiglia", and "1907".
