The Technical Committee of Referees (CTA), under the Royal Spanish Football Federation (RFEF), issued a statement strongly condemning the online abuse and threats directed at Montero and his family following the match.
It read: "The professional referees wish to express our absolute rejection of the attacks and threats that our colleague José Luis Munuera Montero is receiving through social media, which affect him personally as well as his family environment.
"These attacks add to the hate and verbal violence with which we have to perform our professional work every weekend and which in the grassroots categories often turns into, even more regrettably, physical violence in many more cases."
