The horse row has escalated into a full-scale attack on not only the manager but the United board, who have refused to give in to their demands for answers to how the club is run. The whole row has become so bitter that the Irish pair have hired corporate detectives Kroll to look into every aspect of Sir Alex Ferguson's personal and professional life, after he took out a legal action claiming he is half-owner of the stud rights to the horse, which could amount to more than £200million.
