David O'Leary has asked FIFA to intervene in a contract dispute with his former club Al Ahli.
Irishman O'Leary was sacked as manager by the United Arab Emirates outfit in April last year but has yet to receive the compensation he believes he is due for the two remaining years of his three-year deal.
O'Leary has decided to take his case to the world game's governing body via the Football Association.
Graham Noakes, head of Professional Game at the FA, confirmed: "Following application from Mr O'Leary's advisors, the FA has referred this matter to FIFA which has the authority to intervene in disputes of this kind.''
Richard Bevan, chief executive of the League Managers Association (LMA), said: "David O'Leary has been left with no option but to place his contractual dispute with Al Ahli before the Players' Status Committee/Dispute Resolution Chamber of FIFA.
"The LMA is committed to protecting, and, where necessary, enforcing the legal rights of its members, and to ensuring that clubs honour their contractual obligations in the all too frequent event of a manager's dismissal.
"Our commitment to this goal is the same whether our member works at home or abroad.''
