Not only that, it means decent players like Herrera can ask for £300k a week, because there's a flop contributing nothing on more. It also means we're stuck with said flop, because unless he is subsidized no one will have him.
Should be a lesson, but we did it again, giving our goalkeeper £375k, despite keepers in better form making less than half of that, and having two other very good keepers ourselves. It's not like our backs were against the wall.
Pogba, being our star outfield player, probably feels he deserves to be the club's highest earner. If he's not offered that he may feel unappreciated ( Not saying that is his issue, but probably plays a part) .
A disorganized wage structure is a recipe for discontent, and is bound to affect team performance.
