UEFA-appointed inspectors have concluded that FC Barcelona should be prohibited from playing in the Champions League for one season due to their involvement in the 'Caso Negreira' referee payments scandal. The inspectors, Jean Samuel Leuba and Mirjam Koller Trunz, believe that Barca violated UEFA's laws and attempted to influence match outcomes. The final decision rests with UEFA president Aleksander Ceferin, who may wait for the Spanish court's ruling or act on the recommendations of the inspectors.
