Real Madrid and Sevilla have been awarded just 6,000 tickets each for the 2014 European Super Cup, which will take place at the end of August.
With Los Blancos winning the Champions League last season and Sevilla claiming the Europa League, the Spanish pair will meet in the Super Cup at the Cardiff City Stadium.
However, according to AS, it is understood that both clubs are annoyed with UEFA's decision to award just 6,000 tickets apiece.
The same report has claimed that 12,000 will go to the general public, while another 6,000 will be handed to special guests.
