On Thursday a Premier League Tribunal began to consider the circumstances that led to Martin O'Neill's abrupt departure from the manager's job at Aston Villa. O'Neill has refused to shed any light on why he left Villa last August.
The tribunal follows the failure of a mediation process to resolve his dispute with the club late last year.
The Premier League Managers' Arbitration tribunal is only the third involving a manager in recent years.
This hearing, chaired by a QC, is designed to avoid the expense and time of going to the High Court.
It will be up to the panel chairman to decide how much of the evidence, submissions of the parties, and the panel's findings are made public.
The tribunal could sit for at least a week and there is no deadline for a ruling to be announced.
