Alan Curbishley is taking his £1 million compo case against West Ham to a tribunal.
The Sunday Mirror says Curbishley is claiming constructive dismissal after quitting Upton Park in September over disagreements about the club's transfer policy.
Both Curbishley and West Ham have agreed that the dispute should be settled outside the courtroom.
And the former Charlton boss has posted a £5,000 bond with the Premier League so that an independent tribunal can be set up to hear his claim.
