Assuming it’s true, I will say the side effect of the financial regs meaning you buy players who in all likelihood will never play for you is wholly unsatisfying.
Sadly, the way things stand, its pretty clear to me that making profits from player sales/trading is one of the "financial levers" we're going to have to use to help our financials.
Citeh and Chelsea have been doing this for years.
It wouldn't surprise me if (irrespective of PSR machinations,) NWSE have given Monchi & Co a player trading profit to be earned from buying and selling young players.
A sad indictment of the modern game
