The nature of this dispute is totally outside their expertise, and given the threats of litigation flying around their sources have probably clammed up about it.I think the reason why the likes of Ornstein, John Percy and Matt Law are quiet is because no one knows where things are truthfully.
My best guess as to what happened is that Gibbs-White had expressed a desire to move this summer, the club were exploring it, but they preferred the Elanga deal, and once that was finalized they told Gibbs-White he wouldn't be allowed to move, which then induced the disclosure of the release clause that kicked off this whole imbroglio.
If we assume away the release clause (which I guess is the reality we live in now) they're in okay shape to have him run one more year off his deal.
