As I said previously, but seemed to be in the minority, I just couldn't envisage anyone agreeing to something like that. If they wanted potential future income, they would just add a bit on to the club selling price to reflect the team value as an asset.
Exactly, the value of KLP as a player would be included in the value of the club and the sale price as would any asset. Putting daft clauses in would be preposterous and wide open to loopholes and abuse like sending him on loan for 2 years.
