Will be interesting if this sort of stuff hurts PSG in the future with respect to signing to players. I understand why they do it. They pay obscene salaries and transfer fees and if you were tempted by above market salaries for teams outside a top 4 league, they'll hold you too. It just might lead to players thinking - "wow, that's a lot of money, but I also know when PSG puts out a 100MM fee and pays me 10MM/Y, I'm there until end of contract.
Juve is the opposite. Top team in top 4 league that low balls you, but says that if you want out you just need to ask lol.
