You have to read more into it than just transfers. Investing in the training ground, stadium, in the area around, and Newcastle in general, does not affect PSR.
Being the Saudis, with a near limitless pool of money they could have done MUCH more, and they should have, if they were just a tad serious about making us a real force in Europe / Worldwide.
It would have helped us a HELL of a lot, if they didn’t offer stupidly high fees for other clubs players in the EPL. They should not have done that at all.
