Anderlecht have been fined for naming Vincent Kompany as head coach without him having the proper qualifications.
Belgium requires all head coaches of top-flight clubs to hold a UEFA Pro licence.
Kompany was named as player-manager in May without having earned the qualification.
The Belgian giants have now been fined 5,000 over the incident.
"The club violated the regulations for a long time and despite that it being against the rules did not hesitate to publicly unveil a coach without a diploma," the associations licensing committee said in a statement.
