True but it's an odd conversation to have at all with anyone IF you've the slightest doubt about YOUR situation. MoldeFK leaked the conversation to cause maximum amount of alarm bells ringing I would think, so that everyone would know the consequences of OGS leaving - it would mean others leaving too.
As Jarpie correctly said this is either a case of emotional blackmail...... ... or a facesaver all round that actually AVFC hadn't/weren't going to offer him the job anyhow..
Of course the other explanation could be that big wads of dosh changed hands.
What I've read about Rökke, I wouldn't be surprised if he went "I'll make things very difficult for Molde, the staff and the players if you leave - they will be utterly screwed".
