I'm sorry you'll have to explain how this impacts transfer fees.
All I can see is the FIFA preventing deals happening based on whether or not tbh have a particular cert, which has been deemed illegal.
SorryThere already is a thread about this ruling:

And no, it doesn't.
You understand the consequences if a player has the right to terminate his contract, legally, at any time, yes? Same as you can do with your job.
Imagine if we're signing a player for 50 million and that ingrate doesn't like it in Manchester. Him being able to walk away destroys all squad planning.
Not sure how that ruling will be implemented into the current rules, but it has the potential to significantly change the transfer system as we know it.
