I'm not really sure what I think of this, there are two sides to it. If everyone has a release clause then the holding club is powerless, and the big money clubs can just take whoever they want. Seems to me that's almost how it is already, but that would complete their dominance.
I think it stops the silly money and gives the club a fair price for their player if they want to leave, it's not like we would have a low amount in for the likes of Coutinho. So the player gets to move the club get money to reinvest. I think it's better than the crazy that was this Summer.
You did overspend big time, so did a few other clubs.
