That’s the point I’m making.
If it was simply a case of getting a percentage of the original transfer fee then teams would sell players for next to nothing with incredibly simple fees making up the actual bulk of the transfer.
Why would Coventry sell Gyokeres for £20m and give us 20% when...
I admire your confidence about something you are entirely wrong about.
If the sell-on clause stopped the second Coventry sold the player then why wouldn't they have sold him for a fiver + £xm when he makes 1 appearance?
Sometimes a modicum of common sense goes a long way.
You don’t see how a club having to give a percentage of the transfer fee to somebody else might make them ask for more money?
That’s certainly an opinion.
