Agents for Charles De Ketelaere are upset with Club Brugge over talks with AC Milan.
Milan are pushing to sign the Belgium attacker this summer as a priority.
However, Club Brugge's asking price is proving too steep for the Rossonero's new owners.
Milan Reports is stating a member of De Ketelaere's management team says Club Brugge have set an “unrealistic amount" as a price-tag.
De Ketelaere, for his part, would like a move to the Rossoneri as he believes that the environment of the Serie A champions would be the best for his development.
Leeds United have also bid for the youngster - an offer which is superior to Milan's.
