It was reported in the CT that we get 10% of any profit Bournemouth get if they sell him. Hopefully there were other payment clauses added, but I doubt it.
I think it would be better for City if Bournemouth miss out on promotion and Wilson gets sold on to a Premier club. As others suggest, I doubt the team would see a penny, just like when he was sold last summer.
The undisclosed fee thing is total rubbish all fans are nosey and want to see how much we paid or sold them for, when you look on deadline day nearly all are undisclosed.
Would be great to think something has been built into this deal but as Waggott was involved I doubt it.
