Another match fixing scandal could be about to rock European football.

According to reports, Spanish police have launched a match-fixing investigation relating to El Clasico, after an assistant referee in Spain said he's been pressured into making decisions that benefit Real Madrid in their game against Barcelona next month.

Spanish newspaper Cadena COPE have published a legal paper showing that investigation has begun. The report says that Jose Angel Jimenez Munoz de Morales, a member of Spain's Technical Committee of Referees, is the man allegedly responsible for passing down instructions on how the assistant referee should act.

According to Sportthe original phone call pressuring the officials to favour Real was made in September. Legal proceedings were launched on October 19th.

As the biggest game in world football, El Clasico officials always come under the greatest level of scrutiny – especially from partisan Spanish press. Real face Barca at the Santiago Bernabeu on November 21st.
