If we sell him and Real Madrid can't afford the fee, can we ask for a cut of their income derived from his image/commercial rights? Would that be against any FIFA rule?
That way, they can't say they don't have the money. And they can't argue he's not worth the amount, since we are literally asking for a percentage of what he's worth. And if they refuse, it gives Zidane an excuse to throw a fit about the hierarchy placing commercial interest above football.
The last one doesn't benefit us in any way. It's just something I wouldn't mind seeing happen.
