At the very least this breaks a number of PL rules I would imagine.
But yes, I doubt the club are bobothered.
Putting aside the contractual situations, which are for the clubs and employees to sort internally if they want to, what PL rules does it break? Being 'fair towards others'? There would also have to be a complaint for the PL to look at anything, presumably.
And how did the papers get a hold of it.
