It would be nice to know. But do you think the club (any club) would make public their contract dealings and offerings to staff?
And as a general rule, I reckon the club (any club) would be trying to tie down their better players to longer deals constantly. It wouldn’t make a lot of sense to just let a major asset walk out the door for nothing, if it would be remotely possible to sell them for a few mill, even with an outlay of a bit more wages.
And a lot of stick can be thrown at PS for various reasons, but “silly with money” is not one of them.
