Ramon believes an influx of shareholder fans provides a "great opportunity" and can create a more financially stable and healthy environment for football teams.
"Across Europe, a movement is developing that aims to promote the influence of fans at football clubs," he told CNN.
On November 7, Supporters Direct Europe, the association of European football fans, presented a list of demands to the European Parliament in Brussels, including greater involvement for supporters in their clubs and financial fair play.
"The social role of football is of great importance," said Ivo Belet, a member of European Parliament involved with the movement.
"This is the reason supporters should have a say in the management of their clubs."
Uncertain future for Oviedo
Although the future of Real Oviedo remains far from certain, Diaz says he would expect nothing less of the club he has followed since he was a boy.
"It is quite a poetic situation -- a club on the verge of extinction -- and I think in the last minutes everything will be solved. In injury time, we will come out fighting and gain victory."
Diaz thinks Real Oviedo will play until the end of this season, even if the club does not meet its November 17 deadline -- when the team faces a tough trip away to the reserve side of second-placed La Liga club Atletico Madrid.
"It's the same of story for the fans, we will suffer to the very end."
