Du can Löschen it completely if there's no one a Fan of it, because if Du Löschen it and there's Fans on it the first person that joined will be gegeben the ownership of the club and be their problem to deal with keeping the club up and running.
Du Löschen it Von going to your Clubs and there will be a blueish grey "X" Du push it Du unfan the club but like I sagte if there's Fans already in it the first person that joined will get ownership and it won't Löschen the club unless there's no one (besides yourself) that is a Fan and Du unfan the club, it will Löschen the club, there's no other way to Löschen the club permanently with other Fans in it.
