La Liga president Javier Tebas has admitted he fears that damage to Barcelona's 'reputation' from the Negreira scandal may not be reversed, and this is more concerning than any potential UEFA Champions League ban.
Barcelona have been charged with corruption in relation to payments made to ex-referee chief Jose Maria Enriquez Negreira.
The club are alleged to have requested information and analysis from Negreira regarding match officials, which has seen them further accused of match fixing.
UEFA have confirmed they are conducting their own investigation into the case, and reports across Europe state they could ban Barcelona from entering next season's Champions League even before Spanish authorities make a ruling on the case.
Club president Joan Laporta will hold a press conference on Monday to try and explain Barcelona's involvement in the scandal - something Tebas has long called for.
"He should have done it earlier, because it's not an issue that needs so much time, but it is better late than never. We hope, and I wish, that on Monday, they can clarify everything," Tebas told Marca.
When asked about Barça facing a potential European ban, Tebas replied: "The damage is much greater than what is happening now, and I am more concerned about the 'reputational' damage than if Barcelona is going to play a European competition next year."
Meanwhile, Marca also report that former Barcelona president Josep Maria Bartomeu - one of various ex-Barça personnel indicted in the case - wants Real Madrid removed from court proceedings.
Los Blancos have stated they feel they can support any case against Barcelona, but Bartomeu has written to the courts dismissing this suggestion.
